Adobe audition 3.0 manual

The higher the frequency, the higher the musical pitch. Phase Measured in degrees, indicates the position of a waveform in a cycle. Wavelength Measured in units such as inches or centimeters, is the distance between two points with the same degree of phase.

As frequency increases, wavelength decreases. Wavelength B. Degree of phase C. Amplitude D. One second. When two or more sound waves meet, they add to and subtract from each other. If their peaks and troughs are perfectly in phase, they reinforce each other, resulting in a waveform that has higher amplitude than either individual waveform.

If the peaks and troughs of two waveforms are perfectly out of phase , they cancel each other out, resulting in no waveform at all. In most cases, however, waves are out of phase in varying amounts, resulting in a combined waveform that is more complex than individual waveforms.

A complex waveform that represents music, voice, noise, and other sounds, for example, combines the waveforms from each sound together. Because of its unique physical structure, a single instrument can create extremely complex waves. A microphone converts the pressure waves of sound into voltage changes in a wire: high pressure becomes positive voltage, and low pressure becomes negative voltage. When these voltage changes travel down a microphone wire, they can be recorded onto tape as changes in magnetic strength or onto vinyl records as changes in groove size.

A speaker works like a microphone in reverse, taking the voltage signals from an audio recording and vibrating to recreate the pressure wave. Unlike analog storage media such as magnetic tape or vinyl records, computers store audio information digitally as a series of zeroes and ones. In digital storage, the original waveform is broken up into individual snapshots called samples. This process is typically known as digitizing or sampling the audio, but it is sometimes called analog-to- digital conversion.

When you record from a microphone into a computer, for example, analog-to-digital converters transform the analog signal into digital samples that computers can store and process. Sample rate indicates the number of digital snapshots taken of an audio signal each second. This rate determines the frequency range of an audio file. The higher the sample rate, the closer the shape of the digital waveform is to that of the original analog waveform. Low sample rates limit the range of frequencies that can be recorded, which can result in a recording that poorly represents the original sound.

Low sample rate that distorts the original sound wave. High sample rate that perfectly reproduces the original sound wave. To reproduce a given frequency, the sample rate must be at least twice that frequency.

For example, CDs have a sample rate of 44, samples per second, so they can reproduce frequencies up to 22, Hz, which is beyond the limit of human hearing, 20, Hz. Just as sample rate determines frequency range, bit depth determines dynamic range. Higher bit depth provides more possible amplitude values, producing greater dynamic range, a lower noise floor, and higher fidelity:.

An audio file on your hard drive, such as a WAV file, consists of a small header indicating sample rate and bit depth, and then a long series of numbers, one for each sample. These files can be very large. For example, at 44, samples per second and 16 bits per sample, a file requires 86 KB per second—about 5 MB per minute. That figure doubles to 10 MB per minute for a stereo CD, which has two channels.

When you record audio in Adobe Audition, the sound card starts the recording process and specifies what sample rate and bit depth to use. Through Line In or Microphone In ports, the sound card receives analog audio and digitally samples it at the specified rate. Adobe Audition stores each sample in sequence until you stop recording. When you play a file in Adobe Audition, the process happens in reverse.

Adobe Audition sends a series of digital samples to the sound card. The card reconstructs the original waveform and sends it as an analog signal through Line Out ports to your speakers. To summarize, the process of digitizing audio starts with a pressure wave in the air. A microphone converts this pressure wave into voltage changes.

A sound card converts these voltage changes into digital samples. After analog sound becomes digital audio, Adobe Audition can record, edit, process, and mix it—the possibilities are limited only by your imagination. Adobe Audition provides three distinct views, each optimized for unique audio workflows:. With the integrated environment of Adobe Audition, you can move seamlessly between these views, simultaneously editing and mixing files to create polished, professional audio. This integrated environment extends to Adobe video applications, where you can easily incorporate Adobe Audition into comprehensive video-editing workflows.

Open file 2. Edit audio 3. Apply effects 4. Save changes. In Edit View, you edit, restore, and enhance individual audio files, such as voiceovers, old vinyl recordings, and more.

Any saved changes are permanent, making Edit View a great choice for mastering and finalizing files. Open an existing audio file that you want to modify. In the Main panel, trim or extend a file by deleting or generating audio.

To create a sonic collage, combine pasted audio from multiple files. Then, select noise or other audio you want to process with effects.

In the rack, you can edit and reorder effects until you achieve the perfect results. Save the polished, final file to disk, or automatically insert it in CD View or a multitrack session. In Multitrack View, you layer multiple audio files to create stereo or surround-sound mixes. When you create a new session, you specify the sample rate for audio clips the session will contain.

To build a particularly flexible session, insert audio loops—you can choose from over on the Adobe Audition Loopology DVD. In the Main panel, arrange and edit clips in the timeline. In Multitrack View, edits are impermanent for maximum flexibility. But if you want to permanently edit a clip, simply double-click it to enter Edit View.

Apply effects in the Effects Rack, where you can edit, group, and reorder effects on each track. At any future time, you can update or remove effects to address the needs of different audio projects. In the Mixer or Main panel, output audio tracks directly to the Master track for standard mixes.

As you build more complex mixes, combine related tracks in buses, and use sends to output individual tracks to multiple destinations. Then automate effect and mix settings over time, creating a dynamic, evolving mix that highlights different musical passages.

Export your finished mix to a file, which you can automatically insert in Edit View for mastering or CD View for archiving and distributing. However, all three views have similar basic components, such as view buttons, the Main panel, and the status bar. View buttons B.

Menu bar C. Toolbar D. Shortcut bar E. Main panel F. Various other panels G. Status bar. Adobe Audition provides different views for editing audio files and creating multitrack mixes.

To edit individual files, use Edit View. Edit View and Multitrack View use different editing methods, and each has unique advantages. Edit View uses a destructive method, which changes audio data, permanently altering saved files. Such permanent changes are preferable when converting sample rate and bit depth, mastering, or batch processing. Multitrack View uses a nondestructive method, which is impermanent and instantaneous, requiring more processing power, but increasing flexibility.

This flexibility is preferable when gradually building and reevaluating a multilayered musical composition or video soundtrack. You can combine destructive and nondestructive editing to suit the needs of a project. If a multitrack clip requires destructive editing, for example, simply double-click it to enter Edit View.

Alternatively, double-click a file in the Files panel. Or, select an audio clip in either the Files panel or the Main panel, and then click the Edit File button in the Files panel. Zooming adjusts the view of the timeline display in the Main panel. The ideal zoom level depends on your current task.

For example, you can zoom in to see details in an audio file or multitrack session, or you can zoom out to get an overview. Adobe Audition provides several ways to zoom. You can either click buttons in the Zoom panel, or drag scroll bars and rulers.

Click buttons in Zoom panel B. Drag scroll bars C. Right-click and drag rulers. When the pointer becomes a magnifying glass with arrows , drag left or right, or up or down. The magnifying glass icon appears, creating a selection that shows you the range that will fill the Main panel. The magnifying glass icon appears, creating a selection of the range that will fill the Main panel. To zoom with the mouse wheel, place the pointer over the appropriate scroll bar or ruler, and roll the wheel.

In Edit View, this zoom method also works when the pointer is over the waveform. You can set the percentage of this zoom on the General tab of the Preferences dialog box. At higher zoom levels, you may need to scroll to see different audio content in the Main panel.

To change the placement of a horizontal scroll bar, right-click it, and choose Above Display or Below Display. This sets the position of the scroll bar for only the current view Edit View or Multitrack View. Horizontal scroll bar B. Vertical scroll bar Multitrack View only C. Vertical ruler Edit View only D. Horizontal ruler. To scroll through tracks with the mouse wheel, place the pointer over the track display, and roll the wheel.

The panel displays this information in the current time format, such as Decimal or Bars And Beats. Adobe video and audio applications provide a consistent, customizable workspace. Although each application has its own set of panels such as Tools, Properties, Timeline, and so on , you move and group panels in the same way across products. The main window of a program is the application window.

Panels are organized in this window in an arrangement called a workspace. The default workspace contains groups of panels as well as panels that stand alone. You customize a workspace by arranging panels in the layout that best suits your working style.

You can create and save several custom workspaces for different tasks—for example, one for editing and one for previewing. You can drag panels to new locations, move panels into or out of a group, place panels alongside each other, and undock a panel so that it floats in a new window above the application window.

As you rearrange panels, the other panels resize automatically to fit the window. You can use floating windows to create a workspace more like those in previous versions of Adobe applications, or to place panels on multiple monitors.

Application window B. Grouped panels C. Individual panel. For a video about the Adobe workspace, see www. You can dock panels together, move panels into or out of a group, and undock a panel so that it floats in a new window above the application window. As you drag a panel, drop zones —areas onto which you can move the panel— become highlighted.

The drop zone you choose determines where the panel is inserted, and whether it docks or groups with other panels. Docking zones exist along the edges of a panel, group, or window. Docking a panel places it adjacent to the existing group, resizing all groups to accommodate the new panel. Grouping zones exist in the middle of a panel or group, and along the tab area of panels.

Grouping a panel stacks it with other panels. When you undock a panel in a floating window, you can add panels to the window or otherwise modify it, as you do the application window. You can use floating windows to make use of a secondary monitor, or to create a workspace like those in earlier versions of Adobe applications.

Undock Frame undocks the panel group. When you release the mouse button, the panel or group appears in a new floating window. If the application window is maximized, drag the panel to the Windows task bar. When you position the pointer over dividers between panel groups, resize icons appear. When you drag these icons, all groups that share the divider are resized.

For example, suppose your workspace contains three panel groups stacked vertically. Do not press Shift. Press the tilde key again to return the panel to its original size. The pointer becomes a double-arrow. The pointer becomes a four-way arrow. Original group with resize icon B. Resized groups. Even if a panel is open, it may be out of sight, beneath other panels. Choosing a panel from the Window menu opens it and brings it to the front.

When you close a panel group in the application window, the other groups resize to make use of the newly available space. When you close a floating window, the panels within it close, too. To increase the available screen space, use multiple monitors. When you work with multiple monitors, the application window appears on the main monitor, and you place floating windows on the second monitor.

Monitor configurations are stored in the workspace. The toolbar provides quick access to tools, the Workspace menu, and buttons that toggle between Edit, Multitrack, and CD View. Some tools are unique to each view. Likewise, some Edit View tools are available only in spectral displays. By default, the toolbar is docked immediately below the menu bar. However, you can undock the toolbar, converting it to the Tools panel, which you can manipulate like any other panel.

A check mark by the Tools command indicates that it is shown. Multitrack View toolbar. The shortcut bar displays buttons that provide quick access to commonly used functions. The shortcut bar appears in the upper part of the application window, below the menu bar and the default location of the toolbar.

To identify a button, place the pointer over the button until a tool tip appears. The status bar runs across the bottom of the Adobe Audition work area. You can show or hide the status bar and select which types of information appear there.

Data Under Cursor B. Sample Format C. File Size D. File Size Time E. Free Space F. Free Space Time G. Keyboard Modifiers H. Display Mode. A check mark indicates that the status bar is visible.

Data Under Cursor Shows information such as channel for stereo files , amplitude measured in decibels , and time hours:minutes:seconds:hundredths of seconds from the beginning of the audio file. This data changes dynamically when you move the pointer. For example, if you see R: — Sample Format Displays sample information about the currently opened waveform Edit View or session file Multitrack View. For example, a 44, kHz bit stereo file is displayed as — bit — stereo. File Size Represents how large the active audio file is, measured in kilobytes.

If you see K in the status bar, then the current waveform or session is kilobytes KB in size. File Size time Shows you the length measured in time of the current waveform or session.

For example, means the waveform or session is 1. CD or 80 min. Free Space time In Edit View and Multitrack View, displays the time remaining for recording, based upon the currently selected sample rate. This value is shown as minutes, seconds, and thousandths of seconds. For example, if Adobe Audition is set to record 8-bit mono audio at 11, kHz, the time remaining might read Change the recording options to bit stereo at 44, kHz, and the time remaining becomes For example, To return to the original setting, click Reset UI.

Each Adobe video and audio application includes several predefined workspaces that optimize the layout of panels for specific tasks. These workspaces optimize the arrangement of panels for specific tasks. You can customize any predefined workspace. Maximum Session Dual Monitor Arranges the Multitrack View work area for a two-monitor setup, displaying the Main panel and application window on one monitor and other panels on the second monitor, providing maximum view of the Main panel display.

Maximum Waveform Editing Dual Monitor Arranges the Edit View work area for a two-monitor setup, displaying the Main panel and application window on one monitor and other panels on the second monitor, providing maximum view of the Main panel display. As you customize a workspace, the application tracks your changes, storing the most recent layout. To store a specific layout more permanently, save a custom workspace.

Saved custom workspaces appear in the Workspace menu, where you can return to and reset them. Type a name for the workspace, and click OK. Note: If a project saved with a custom workspace is opened on another system, the application looks for a workspace with a matching name.

Note: You cannot delete the currently active workspace. You can use a wide range of hardware inputs and outputs with Adobe Audition. Sound card inputs let you bring in audio from sources such as microphones, tape decks, and digital effects units. Sound card outputs let you monitor audio through sources such as speakers and headphones. Sound card inputs connect to sources such as microphones and tape decks. Sound card outputs connect to speakers and headphones.

Some cards support both types of drivers. ASIO drivers are preferable because they provide better performance and lower latency. You can also monitor audio as you record it and instantly hear volume, pan, and effects changes during playback. The main advantage of DirectSound is that you can access one card from multiple applications simultaneously. In a multitrack session, you can override the defaults for a particular track.

The options available will be different than those described below. For more information, consult the documentation for the sound card. When a port is deselected, it is not available as a port option in the Audio Hardware Setup dialog box.

If you hear skips or dropouts in playback, you can adjust buffer size: Double-click the Buffer Size numerical entry for an input or output device, and type a new value. The default is 16 KB, but you can experiment with other sizes which range all the way to the highest buffer size the CD-ROM drive supports.

Start playing the loudest part of the CD. You set the start-time indicator to start playback or recording at a specific point in a waveform. Click the Pause button again to resume playback or recording. Pause Places the playback cursor at the beginning of the next marker. If there are Go To Beginning Or Previous Marker no markers, the playback cursor moves to the beginning of the waveform or session.

Enter the starting time and date in the appropriate text boxes, and set the desired time and date options. Page 62 Prior to recording in a session, you must save it so that Adobe Audition can store recorded clips in the session folder.

Page 63 Loop while recording in Multitrack View If you loop while recording, Adobe Audition saves a new clip for each take. This feature is ideal for difficult musical passages. Simply loop while recording until the performer produces the perfect take. Or combine the best parts of each take to create a new clip.

Page 64 For particularly important or difficult sections, you can punch in multiple takes, and then select or edit takes to create the best performance. Adobe Audition saves two seconds of audio on either side of a punch-in range, so you can seamlessly edit and crossfade takes. Note: You can't punch into a loop-enabled clip. Page Playing Audio Note: By default, the Main panel scrolls in sync with playback that extends beyond the visible section of a waveform.

In the General tab of the Preferences dialog box, you can customize auto-scrolling options or disable this feature. Click OK. Yellow peak indicators remain for 1. Page 69 You may need to adjust levels if recordings are too quiet causing unwanted noise , too loud leading to clipped, distorted sound , or inaudible when played in Adobe Audition. To get the best sounding results, you should record audio as loud as possible without clipping.

Try to keep the loudest peak somewhere between —2 dB and 0 dB when setting recording levels. Each shows you a different visual representation of sound waves. If you open a stereo file, the left channel appears at the top and the right channel appears at the bottom. If you open a mono file, its single channel fills the total height of the Main panel. For example, if you see a lot of inverse phase information in the Phase Analysis panel, you can use Spectral Phase Display to find out exactly where in time the out-of-phase audio is occurring.

To delete a color point, right-click it and choose Delete Color Point. Page 76 At the top of the Main panel, time displays show how much audio is visible for the top and tail. By default, Adobe Audition displays 10 seconds in both views. Page 78 By default, Adobe Audition plays all audio in the same time range as a spectral selection.

To hear only the selection, right-click the standard or circled Play button, and select Play Spectral Selection. Specify which channel you want to edit By default, Adobe Audition applies selections and edits to both channels of a stereo waveform.

However, you can easily select and edit just the left or right channel of a stereo waveform. Page 80 Though you can often identify beats by looking for peaks in a waveform, the Find Beats command makes the task much quicker. After you find beats with this command, Adobe Audition saves them as Beat Markers, making it easy to locate beats again. Page Copying, Cutting, Pasting, And Deleting Audio Copying, cutting, pasting, and deleting audio Choose a clipboard Adobe Audition gives you access to five internal clipboards for temporary data storage.

Each works similarly to the Windows clipboard, except that they can handle more data at a faster rate. Page 82 The Mix Paste command lets you mix audio data from the clipboard or a file with the current waveform. Page Visually Fading And Changing Amplitude Delete or trim audio data Adobe Audition provides two methods for deleting audio: The Delete Selection command lets you remove a range from a waveform, whereas the Trim command lets you remove unwanted audio from both sides of the selected audio.

If this fade sounds too abrupt, however, try one of the other options. A point refers to a specific time position within a waveform for instance, A range has both a start time and an end time for example, all of the waveform from Page 86 Marker types Adobe Audition provides five marker types. All five can be ranges as well as points. You can change marker types by clicking Edit Marker Info in the Markers panel and choosing a marker type from the Type menu. Alternatively, right-click the marker handle, and choose a marker type from the context menu.

In the For More Than text box, enter the duration in milliseconds of this maximum amplitude value. Page 90 Enter a longer duration to ignore short periods of undesired audio like clicks, static, or other noise.

However, if the value is too high above milliseconds , short words may be skipped. Scans the waveform or a selected range to have Adobe Audition automatically determine a good Find Levels starting point for signal levels.

Higher values can lead to an artificial sounding pause. Previews the silence to be removed. This option reports how much silence will be removed Scan For Silence Now and how many sections of silence were found. Page Generating Audio Specifies the length that is assigned to the pause character when it is used in the Dial String text box.

Pause Time Specifies which character Adobe Audition interprets as a pause. Page 94 Each color has its own characteristics. Generating noise is useful for creating soothing sounds like waterfalls perfect for use with the Binaural Auto-Panner function of Adobe Audition and for generating signals that can be used to check out the frequency response of a speaker, microphone, or other audio system component.

For example, you can apply DC Offset to correct an incoming signal that has suffered electrical pollution from a strong adjacent current. If you select a range, Adobe Audition analyzes the center point of the range. Page 99 In the Main panel, click a point, select a range, or start playback.

If you select a range, Adobe Audition analyzes only the center point. To analyze the overall frequency of a selected range, click Scan Selection in the Frequency Analysis panel. Page You can generate a step-by-step animation by clicking the Main panel and then holding down the Right Arrow key. As the cursor scrolls across the across the waveform, Adobe Audition displays the corresponding spectral infor- mation in the Frequency Analysis panel.

In Edit View, select an audio range. Page Specifies the number of milliseconds in each RMS window. To achieve the most accurate RMS values, use wide windows for audio with a wide dynamic range, and narrow windows for audio with a narrow dynamic range. Page Converting Sample Types Enter a sample rate in the text box, or choose a common sample rate from the list.

Note: Although you can work with any sample rate in Adobe Audition, your sound card may not be capable of playing all rates properly. To determine supported sample rates, consult the documentation for the card. Page Select a bit depth from the Resolution list, or enter a custom bit depth in the text box. When you select a lower bit depth, Adobe Audition provides dithering options to help reduce noise and distortion. Set the following options as desired, and click OK: Although dithering introduces a small amount of white noise, the result is far preferable to the increased distortion that you would otherwise hear at low signal levels.

Usually, Triangular p. These changes are stored in a temporary file on your hard drive. In both racks, you can insert, edit, and reorder up to 16 effects, optimize mix levels, and store favorite presets. Each track has its own Effects Rack, which is saved with the session. Dock the Effects Rack to quickly view and edit effect settings for multiple tracks. Page To modify an existing preset, apply it, adjust settings as desired, and then save a new preset with the same name.

Control effects settings with graphs Many Adobe Audition effects provide graphs where you can adjust parameters. By adding and moving control points on the graph, you can precisely tailor effect settings. When the pointer is over a control point, the pointer changes from an arrow to a hand. You can change the grouping of effects to best meet your needs.

To readapt a session for different projects, for example, simply reopen it and change effects to create new sonic textures. Be aware that enabling large numbers of plug-ins can cause Adobe Audition to start slowly. Select the plug-ins you want to access in Adobe Audition, and then click OK. Though you can select VST instru- ments here, they are unsupported for audio processing. Applies a logarithmic-style fade also known as a power fade. If you select this option, You can choose Compress, Flat, or Expand for up to six sections or stages, each with its own ratio and threshold setting.

For example, to create a compressor above dB, choose Compress, and then specify a ratio and a threshold of dB. Use the Envelope effect to make tones generated with Adobe Audition sound more realistic.

This effect is particularly useful for increasing perceived volume because you can amplify audio beyond the digital maximum, 0 dbFS, and you can lower areas that would otherwise be clipped. Frequency bands B. Crossover markers C. Bypassed band no processing applied D. Amplitude scale E. Possible values range from to 0 dB. The best Threshold sliders setting depends on audio content and musical style. To compress only extreme peaks and retain more dynamic range, try thresholds around 5 dB below the peak input level; If desired, you can apply that command to only one file.

Page Delay And Echo Effects When reverb or chorus might muddy the mix, both delays and echoes are a great way to add ambience to a track. To access familiar options from hardware delays, use the Echo effect in Adobe Audition. Page 35 milliseconds or more create discrete echoes, while those between milliseconds can create a simple chorus or flanging effect. Original and Delayed Inverts the delayed signal, causing the waves to cancel out periodically, instead of reinforcing the signal.

Page The number of echoes is adjustable up to , Keep in mind that the more echoes you include, the more time Adobe Audition needs to process the effect. Page The distance between the source and the walls affects which frequencies are enhanced and is crucial to the overall ambient effect.

If you enter a value that exceeds the dimensions of the room, Adobe Audition uses the greatest possible value based on the dimensions. It is then mixed into Delay Offset an earlier point in the delay line, which causes echoing. However, you can create interesting effects by entering positive values. Boosting a Low Cut Filter while reducing the feedback setting is identical to reducing a High Cut Filter and increasing the feedback setting.

Adjusts the amount of amplitude or attenuation the Dynamic EQ effect uses. A larger number low factor causes the filter settings to change roughly or in chunks from initial to final, while smaller numbers higher factor make the transition much smoother. Compensates for an overall volume level that is too soft or too loud after the EQ settings are adjusted. Master Gain The default value of 0 dB represents no master gain adjustment.

Set the cutoff frequency with High Shelf Cutoff and Level the second slider below the graph, and increase or decrease treble with the slider at the right of the graph. Use the High Shelf Cutoff to reduce hiss, amplifier noise, and the like. If this option is deselected, you can specify separate initial and final equalization settings, so that the selection can smoothly glide from the initial equalization setting to the final setting over the selected range. Click the Initial Settings and Final Settings tabs to specify initial and final settings.

Page Modulation Effects You can also use it to create some truly out-of-this-world special effects. Adobe Audition uses a direct-simulation method of achieving a chorus effect, making each voice or layer sound distinct from the original by slightly varying timing, intonation, and vibrato.

The Feedback setting lets you add extra detail to the result. High values cause the separate voices to start at different times—the higher the value, the farther apart the onset of each voice may be. It was originally achieved by sending an identical audio signal to two reel-to-reel tape recorders, and then pressing the flange of one reel to slow it down. First, use Spectral Frequency Display to visually identify and select ranges of noise or individual artifacts.

Values between 6 and 30 dB work well. To reduce bubbly Reduce Noise By background effects, enter lower values. Page Use Effect Presets Detection graph ruler x-axis and threshold level along the vertical ruler y-axis. Adobe Audition uses values on the curve to the right above dB or so when processing louder audio and values on the left when processing softer audio. Curves are color-coded to indicate detection and rejection. For example, if a quiet part still has a lot of clicks, lower the Min Threshold level a bit.

If a loud piece still has clicks, lower the Avg or Max Threshold level. Page A higher detection threshold might lead to fewer repairs and increase the quality while still removing all clicks. Determines the FFT size used to repair clicks, pops, and crackle.

Page FFT Size option in other situations might help with some types of clipping. Try a setting of 40 for normal clipped audio. In general, however, leave FFT Size unselected. In many cases, you can simply reset the graph to an even level and manipulate the Noise Floor Adjust slider. Fine-tunes the noise floor until the appropriate amount of hiss reduction and quality level is Noise Floor Adjust achieved. Extracts a noise profile from a selected range, indicating only background noise.

Adobe Audition Capture Profile gathers statistical information about the background noise so it can remove it from the remainder of the waveform. Page will likely cut out more noise, but also cut out more original signal. However, a low noise reduction level with more samples will also cut out more noise, but likely will not disrupt the intended signal.

However, you can Load From File apply noise profiles only to identical sample types. Page Reverb Effects This reflected sound is called reverberation, or reverb for short. With Adobe Audition, you can use reverb effects to simulate a variety of room environments.

Convolution- based reverbs use impulse files to simulate acoustic spaces. The results are incredibly realistic and life-like. If desired, you can then fine-tune the decay length and pre-delay.

The Reverb effect can create a wide range of high-quality results. It can reproduce acoustic or ambient environments such as a coat closet, a tiled bathroom shower, a concert hall, or a grand amphitheater. In general, the more reverb you add, the lower the volume of the original signal. Device Properties. Wave Out Tab. Wave In Tab. Device Order. About Images. About Blocks. About Session Files.

This means you can do anything from creating a totally new soundtrack, to sweetening the recording you already have, to reducing noise on the current soundtrack. Loops automatically match global session tempo and key to produce dynamic musical performances.

Thousands of royalty-free production music loops Adobe Audition includes thousands of original, performance-based loops in a wide range of musical genres that you can combine to create your own music beds, songs, soundtracks, and more. One key point is the way in which an audio program operates on a waveform. There are two kinds of computer-based audio editing: destructive and non-destructive. Adobe Audition employs both destructive and non-destructive editing methods. The use of real-time effects in Multitrack View is non-destructive as well.

This same model of delayed destructive editing also enables Adobe Audition to offer multiple levels of Undo. It does this for each edit you perform, enabling you to travel back through your edits to previous states of the waveform. Multiple Undo gives you tremendous freedom in working on waveforms without having to worry about destructiveness in the least. However, it also requires additional hard drive space to store these copies.

You can disable the Undo feature if your disk space runs too low. In the Edit View, Adobe Audition offers real-time preview for many of its effects. This means that you can monitor the processed signal before applying the effect to the waveform. Remember: the effect is actually applied to a copy of the waveform, and can be freely undone. The preview feature updates in real time, meaning that changes you make to effect parameters while in the dialog for that effect become audible immediately, while the audio is playing.

On slower systems, some effects may tend to break up or skip during preview. In multitrack the preview is not necessary, as effects are used non-destructively. Basically, every effect in the Multitrack View is in preview all the time. The mixing process involves combining the audio of all of the placed blocks into two or more channels for output.

When something is altered, Adobe Audition must immediately work that change into the mixed output, and it does so through background mixing. Background mixing occurs behind the scenes and is generally very fast. The faster your system — especially your CPU and hard drive s — the faster Adobe Audition can mix in the background. However, you need not wait for the meter to reach completion entirely before beginning playback. As stated above, Adobe Audition continuously mixes, and will continue to do so while playing, so you can safely begin playback when the Mix Gauge meter is about halfway up.

If that happens, just wait a few seconds — Adobe Audition will usually catch up very quickly, and you can begin playing again. Your audio might also start to break up if you are using real-time effects in multitrack view and your system cannot keep up with the processing. If this happens, try using the Lock feature on some of your effected tracks to mix the effects into the background mix and take some load off of your CPU.

Playback can be directed to a pair of outputs as in a single stereo sound card or to multiple outputs as in multiple stereo sound cards, or a single card with multiple outputs.

Adobe Audition produces a mix for each set of outputs used. The additional mixing required for multiple outputs demands more processing power and therefore tends to slow down the mixing process. This chapter is meant to be a brief introduction to the various navigation and functional controls of this deceptively simple — yet powerful — program. Whenever you see a simple function button, control, window, or waveform action, try right-clicking it.

While in Edit View, Adobe Audition can be thought of as being a single-waveform editor that can be used to record, edit, and process mono and stereo waveforms.

On the other hand, Multitrack View is where Adobe Audition allows you to record, play, and mix multiple tracks of audio in a virtual track recording studio. Real-time effects can be applied, relative track volume and stereo placement may be adjusted, and audio can be played back through single or multiple sound cards.

There are several ways to switch from Edit View to Multitrack View. Here are the most popular:. Several methods are provided to switch from Multitrack View to Edit View. These include:. How can you tell if a part of the Adobe Audition interface is indeed a dockable window? Move your mouse over a handle, and your mouse cursor looks like a plus sign with arrows at each end.

Some docked windows may be resized. If resizing is possible, the docked window will have a single, thicker horizontal or vertical bar, known as a resize control.

If your mouse moves over a resize control, your mouse cursor takes on the appearance of two lines with two arrows. Notice how the window becomes outlined when selected.
