Save a session After you are done with your work, you can save the file the session using the File - Save session menu item while the multitrack view is activated. Please note that this will not give you a file that you can afterwards play in Winamp of any other music player.
It will be a format specific to Adobe Audition. Note: If you have recorded a sound, that sound cannot be saved in the session file and it does not exist on your computer, so you must save it separately. Adobe Audition will offer to save it as a separate sound file, in a compressed file format wma.
If you need high quality for the recorded sound, you should switch to wav format. Basic audio editing 1. The Undo feature. This is one of the most important features to know about. Note that these backups are discarded once you close the program.
Making a selection. To select a section of a file in edit mode you want to work on, you use the mouse as you would for selecting text in a word processor: you click at the position you want to start your selection and drag the mouse, while keeping the left button pressed, to the position you want to end the selection; at that point you release the mouse button.
Record If you need to record something and you are in multiview mode, you need to decide on a track you will record on. Skip to the next paragraph if you are in edit mode. You most likely want to select an empty track. Once you decided on the track you want, click on it, and arm it for recording. You can start recording by then clicking on the record button in the bottom section where the controls are. To stop the recording, click on the record button in the bottom section again.
If you can record from multiple devices, you can select the one you want to record from by clicking the button below the arming button you need to be in multiview mode. Just arm the track and press record. It will just work. Deleting part of the whole content of a track Select the part you want to delete by clicking on it. Then press Del key.
Moving a sound along the timeline within the track, or to a new track Click the part you want to move, and drag it to where you want to put it. Splitting a sound Select the track with the sound you want to split. Notice a vertical yellow cursor that goes through flirtfm. Drag that cursor by clicking and dragging the top yellow triangle of the cursor to the point you want the sound to be split. Use the Edit - Split menu item. General notes: Red color is generally used for recording.
A recorded sound looks red in the track. Green is used for existing sounds. Click the first track. Right-click and select Insert-Audio; select the file you want to process. After loading it may take a few seconds double click on the sound. A speaker works like a microphone in reverse, taking the voltage signals from an audio recording and vibrating to recreate the pressure wave.
Digital audio: zeroes and ones 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-todigital 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 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 theoriginalanalogwaveform.
A B Two sample rates A. 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. See Nyquist frequency on page 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.
Here are the most common sample rates for digital audio:. When a sound wave is sampled, each sample is assigned the amplitude value closest to the original wave s amplitude. Higher bit depth provides more possible amplitude values, producing greater dynamic range, a lower noise floor, and higher fidelity: Bit depth Quality level Amplitude values Dynamic range 8-bit Telephony db bit CD 65, db bit DVD 16,, db bit Best 4,,, db db db 96 db 48 db 0 db 8-bit bit bit bit Higher bit depths provide greater dynamic range.
Audio file contents and size 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. 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. In Multitrack View, you layer multiple audio files, mixing them together to create sophisticated musical compositions and video soundtracks.
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. 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. See Editing audio files on page Open or create a file Open an existing audio file that you want to modify.
Alternatively, create a blank file that you ll record or paste audio into. See Opening audio files in Edit View on page To create a sonic collage, combine pasted audio from multiple files. Then, select noise or other audio you want to process with effects. See Selecting audio on page In the rack, you can edit and reorder effects until you achieve the perfect results.

The edits and effects you apply aren t permanent; if a mix doesn t sound good next week, or even next year, simply change mix settings. See About multitrack sessions on page When you create a new session, you specify the sample rate for audio clips the session will contain. See Opening and adding to sessions in Multitrack View on page To build a particularly flexible session, insert audio loops you can choose from over on the Adobe Audition Loopology DVD.
See Insert an audio file into a session on page 47 and Record audio clips in Multitrack View on page Inserting from the Files panel. 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.
See Arranging clips on page and Editing clips on page Arranging and editing clips in the Main panel Apply effects 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. See Applying effects in Multitrack View on page Applying effects in the Effects Rack. 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.
See Track routing and EQ controls on page and Automating track settings on page Routing and mixing tracks in the Mixer Export Export your finished mix to a file, which you can automatically insert in Edit View for mastering or CD View for archiving and distributing.

Menu bar C. Toolbar D. Shortcut bar E. Main panel F. Various other panels G. Status bar G. 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. Likewise, if an edited waveform contains recent changes that you dislike, use the Undo command to revert to previous states destructive edits aren t applied until you save a file.
For more information about Edit View, see Editing audio files on page 65; for more information about Multitrack View, see Mixing multitrack sessions.
In Multitrack View, double-click an audio clip to open it in 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.

The panel displays this information in the current time format, such as Decimal or Bars And Beats. See To change the time display format on page Monitoring time during recording and playback on page 54 Dock, group, or float panels on page 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. YoucanusefloatingwindowstocreateaworkspacemorelikethoseinpreviousversionsofAdobeapplications,orto place panels on multiple monitors.

Individual panel For a video about the Adobe workspace, see Dock, group, or float panels 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 a panel places it adjacent to the existing group, resizing all groups to accommodate the new panel. Groupingapanelstacksit with other panels. A B C Dragging panel A onto grouping zone B to group it with existing panels C Dock or group panels 1 If the panel you want to dock or group is not visible, choose it from the Window menu.
Drag group gripper to move entire group The application docks or groups the panel, according to the type of drop zone. Undock a panel in a floating window 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.
Select the panel you want to undock if it s not visible, choose it from the Window menu , and then do one of the following: Choose Undock Panel or Undock Frame from the panel menu. Undock Frame undocks the panel group. When you release the mouse button, the panel or group appears in a new floating window. Drag the panel or group outside the application window.
If the application window is maximized, drag the panel to the Windows task bar. Resize panel groups 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. If you drag the divider between the bottom two groups, they are resized, but the topmost group doesn t change. Do not press Shift. Press the tilde key again to return the panel to its original size.
The pointer becomes a double-arrow. To resize in both directions at once, position the pointer at the intersection between three or more panel groups. The pointer becomes a four-way arrow.

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. Port Order If the selected device includes more than one port, click the Move Up or Move Down button to change the order of the ports for that device.
Full Duplex Select this to enable Adobe Audition to record an audio track while another one plays back, if the sound card is capable of doing so. Start Input First This determines the order in which Adobe Audition starts the sound card playback in and record out ports in a multitrack environment. Musical Instrument Digital Interface MIDI is a standard for communicating performance information from one piece of software or hardware to another. To close the Preferences dialog box without changing any options, click Cancel.
When you click OK, most changes take effect immediately. If a change requires you to quit and restart Adobe Audition, you are prompted to do so. For example, you need to quit and restart Adobe Audition when you set up a different temporary folder. In the Preferences dialog box, click the General tab to access the following options:. Force Spacebar To Always Trigger Play Plays a file when the spacebar is pressed, regardless of which dockable window has focus.
Auto-scrolling takes effect only when you zoom in on a portion of a waveform and play past the viewed portion. To extend a selection, Shift-left-click. To see the pop-up menu, Ctrl-right-click. Mouse Wheel Zoom Factor Determines zoom behavior when you turn the mouse wheel on Intellipoint-compatible pointing devices.
Edit View Selections Determines the amount of waveform data that is automatically selected if nothing is already highlighted when you apply an effect. Double-clicking always selects the current view. Triple-clicking always selects the entire waveform. Automatically selects the inserted audio after a paste operation.
Deselect this option to of the inserted audio instead. Deselect this option to quickly append multiple segments of pasted audio. To enable the non-default curve, hold down Ctrl when dragging on-clip fade icons in the Main panel. In the Preferences dialog box, click the System tab to configure how Adobe Audition interacts with your system:.
Cache Size Determines the amount of memory that Adobe Audition reserves for processing data. Recommended cache sizes range from 8 to 32 MB 32 MB is the default. Because undo requires extra disk space for temporary files and extra processing time, you may want to turn this feature off. Lower this number to free up more memory but lose more actions. Temporary Folders Lets you change the location of folders for temporary files, which Adobe Audition creates when you edit audio.
All temporary files begin with AUD and have a. Adobe Audition normally deletes temporary files when it exits. For the options below, click the Browse button to navigate to a new folder location. Ideally, it should be on your fastest hard drive. For best results, specify a different physical hard drive than the primary temp folder. Auto-Save For Recovery Backs up files more frequently than needed for basic crash recovery.
In Adobe Audition, basic crash recovery is on at all times. This option expands that feature, saving backups more frequently. Because this preference can affect performance, select it only if you experience frequent power failures or system crashes. In general, leave this option selected. Usually, after you finish with an Adobe Audition session, these clipboard files are no longer needed and just take up space.
Force Complete Flush Before Saving Disables the quick save feature, which lets Adobe Audition quickly save files that contain only minor modifications. If you select this option, Adobe Audition saves an internal backup copy of entire files, considerably increasing the save time for large files. Select this option only if you have trouble saving back to the same filename or you have a problem with the Adobe Audition quick save feature.
To delete invalid characters without replacing them, leave this box blank. Specify a different option only if you commonly open WAV files in a more unusual format. If you typically open files in one format, this option helps you narrow the displayed list of files.
You can override the default format in the Open dialog box. If you typically save files in one format, this option makes the saving process more efficient. You can override the default format in the Save As dialog box.
In the Preferences dialog box, click the Colors tab to change the Adobe Audition color scheme:. Waveform Lists all elements to which you can assign custom colors. To change the color of an element, select it from the list and click the Change Color button below the Example display. To choose one, select it from the pop-up menu. Save As Saves the currently selected color scheme as a preset. Delete Deletes the currently selected color scheme preset.
Example Displays the currently selected color scheme preset or customized color scheme. Change Color Opens the Color Picker, in which you can select a new color for the element selected under Waveform.
The current color is shown in the color swatch to the left of the Change Color button. Selection Lets you adjust the appearance of a selected range.
Preview your changes in the Example area. Deselect this option if you want to set transparency for selected ranges instead of reversing the colors. This option is not available when Invert is selected. UI Brightness Drag the slider, click the arrows at either end of the brightness scale, or type in a percentage to change the overall brightness of the work area. Tint Colors all panels and dialog boxes with a tint you specify.
In the Preferences dialog box, click the Display tab to adjust the Spectral and Waveform Display modes:. Windowing Function Determines which method Adobe Audition uses to segment the spectral data before displaying it. Blackmann or Blackmann-Harris are usually good choices. Resolution Specifies the number of vertical bands used in drawing frequencies.
The larger this number, the longer it takes for Adobe Audition to render the spectral display. Performance varies according to the speed of your computer. This makes the display more accurate along the timeline left and right , but less accurate along the frequency scale up and down.
Marker and range entries listed in the Marker List appear in the waveform as vertical dotted lines overlaying the audio, connecting the arrows from the top to the bottom of the display.
Show Grid Lines Displays grid lines in the waveform display. The grid lines mark off time on the horizontal x-axis and amplitude on the vertical y-axis. Show Center Lines Displays center lines in the waveform display.
Show Boundary Lines Displays boundary lines in the waveform display. The value in the Display Lines At option specifies the amplitude at which the boundary lines appear. Peak Files Specifies options for peak. Peak files make file opening almost instantaneous by greatly reducing the time it takes to draw the waveform especially with larger files.
Larger values reduce the RAM requirement for large files at the expense of slightly slower drawing at some zoom levels. You can safely delete peak files or deselect this option; however, without peak cache files, larger audio files reopen more slowly.
In the Preferences dialog box, click the Data tab to control how Adobe Audition handles audio data:. All subsequent operations occur in the bit realm.
Interpret Bit PCM. Adobe Audition does most processing using arithmetic greater than bit, with the results converted back to bit when complete. During this conversion, dithering provides a higher dynamic range and cleaner results, with fewer distortions and negative artifacts. With this option enabled, you can approximate bit performance with bit data, because dithering increases dynamic range by about 10 dB.
If this option is disabled, audio data is truncated to bit during reconversion, and more subtle information is lost. The drawback of dithering is that each operation adds a small amount of noise at the quietest volume levels.
Use Symmetric Dithering Enables symmetric dithering. If it is not selected, a DC offset of one-half sample is added each time data is dithered. Symmetric dithering has just as many samples added above zero as below zero. By contrast, nonsymmetric dithering just toggles between 0 and 1.
Sometimes in a final dither, this may be desired to reduce the bit range of the dither. However, both methods produce identical audible results in every respect.
Smooth Delete And Cut Boundaries Over Smooths cut and delete operations at the splicing point, preventing audible clicks at these locations. Applies only the boundaries over the number of milliseconds specified in the edit box. Smooth All Edit Boundaries By Crossfading Automatically applies a crossfade to the starting and ending boundaries of the selection.
This option smooths any abrupt transitions at these end points, thus preventing audible clicks when. You can enter a value in milliseconds in the crossfade time box to specify the crossfade duration. Auto-Convert Settings For Paste When pasting different sample formats, Adobe Audition uses these settings when auto-converting the clipboard to the current sample format.
Higher values retain more high frequencies while still preventing the aliasing of higher frequencies to lower ones. A lower setting results in shorter processing time but also in the roll-off of certain high frequencies, leading to muffled-sounding audio.
Usually values between 80 and are fully satisfactory for most conversion needs. The default value is The prefilter removes all frequencies above the Nyquist limit, thus keeping them from generating alias frequencies at the low end of the spectrum. In general, select this option for best results. A lower setting results in shorter processing time but also rolls off certain high frequencies, leading to muffled-sounding audio. Values between and address most conversion needs.
Use a higher Upsampling Quality Level value whenever you downsample from a high sample rate to a low rate. For upsampling, a lower value produces quality almost identical to a higher value. Downsampling, at even the lowest values, generally doesn't introduce any undesired noisy artifacts.
Instead, the sound might be slightly muffled because of increased high-end filtering. The postfilter removes all frequencies above the Nyquist limit, thus keeping them from generating false frequencies at the low end of the spectrum. The default value of 1 bit enables dithering, while a value of 0 disables dithering. For semidithering, choose a value of 0.
With dithering, you can approximate bit performance with bit data, because dynamic range increases by about 10 dB. This allows signals as quiet as — dB. Allow For Partially Processed Data After Canceling Effect Determines what happens after you click the Cancel button while in the middle of applying an effect to a waveform. When selected, Adobe Audition leaves the effect applied to all data processed up until the point you clicked Cancel.
When deselected, Adobe Audition automatically removes the effect on already processed data when you click Cancel. In the Preferences dialog box, click the Multitrack tab to optimize recording, playback, and mix down:. Defaults Specifies recording and panning settings for multitrack sessions.
Or select Equal-Power Sinusoidal to pan left and right channels with equal power, so that a hard pan left has the same loudness as both channels together. Note: Because Equal-Power Sinusoidal panning can make one channel louder than the original waveform, audible clipping can occur in bit sessions.
To avoid this, work in the bit realm. Audio Mix Down Contains options governing the resolution and dithering of multitrack sessions. Regardless of the session format bit or bit , you can bounce audio at either bit or bit quality with this option. The default is bit. Automation Optimizations Contains options that determine how automated mix parameters are recorded.
You can set values from 0. Enter an interval between 1 and milliseconds in the Minimum Time field. Auto Zero-Cross Edits Automatically adjusts the beginning and end points of all Cut, Copy, and Paste operations to the nearest place where the waveform crosses the center line zero amplitude point.
This often results in an audible pop or click at that point. By default, Adobe Audition uses a paging method of scrolling in Multitrack View instead of the smooth scrolling technique used in Edit View.
This saves on system resources. When you reopen the session, Adobe Audition uses the temporary file instead of refreezing the tracks. Crossfade Time Determines the crossfade duration for overlapping clips. Some Windows systems provide uneven timestamps, causing imprecise synchronization. Lower settings and lower result in faster transport response but may prevent Adobe Audition from establishing synchronization.
Settings of to are sufficient on most systems. This value accounts for discrepancies introduced by sound card buffers. The default value is 10 samples.
A setting of up to 2. The default value is one-quarter. The default value is samples. You can use external controllers, such as the Mackie Control, when recording and mixing in Adobe Audition. These devices let you edit audio tracks using real knobs and automated faders, instead of your mouse and computer keyboard. With an external controller, you can automate settings for several tracks at once.
In the Preferences dialog box, click the External Controllers tab to access the following options:. External Control Device Specifies the controller you want to use. Volume Increment Sets the minimum volume change for the data-entry knob on the controller. Configure Accesses additional options provided by the controller software.
Refer to your controller documentation for more information. When you edit a file, Adobe Audition copies the audio data into a temporary file for internal use.
This process allows for quicker editing, better handling of large files, and the ability to undo changes. When specifying folders for temporary files, you should use hard disks with plenty of free space.
You can use this dialog box to delete temporary files and clear undo items. Use the status bar to monitor the amount of free disk space. Open waveforms B. Undo items for the selected waveform C. Location of primary and secondary temporary folders. The Undo History list displays the actions that are currently being retained on your system and the amount of hard drive space each instance consumes.
Select an item and click Clear Undo s. All items at the selected level and below are removed. This option is useful only if the dialog box automatically appeared because you ran out of storage space. If Adobe Audition crashes, there may be a temp file audxxxx. If an open Windows PCM. Flushing copies audio data from the file to a temporary folder. This happens automatically if you alter the entire audio file. Sample Rate Determines the range of frequencies that can be reproduced. Channels Determines if the waveform is mono or stereo.
This option works well for a voice-only recording.
