New, blank audio files are perfect for recording new audio or combining pasted audio.
Create a new, blank audio file
Determines the frequency range of the file. To reproduce a given frequency, the sample rate must be at least twice that frequency. (See Understanding sample rate.)
For voice-only recordings, the mono option is a good choice that results in quicker processing and smaller files.
Create a new multitrack session
Session (*.sesx) files contain no audio data themselves. Instead, they are small XML-based files that point to other audio files on the hard drive. A session file keeps track of which files are a part of the session, where they are inserted, which envelopes and effects are applied, and so on.
To examine settings in detail, SESX files can be opened in text editors or stored in version control systems (such as Perforce, which is popular in the gaming industry).
Specifies either a default template or one you've created. Session templates specify source files and settings such as Sample Rate and Bit Depth.
Determines the frequency range of the session. To reproduce a given frequency, the sample rate must be at least twice that frequency. (See Understanding sample rate.)
All files added to a session must share the sample rate. If you attempt to import files with different sample rates, Adobe Audition prompts you to resample them, which may lower audio quality. To change resampling quality, adjust the Sample Rate Conversion settings in the Data preferences.
Determines the amplitude range of the session, including recordings and files created with the Multitrack > Mixdown To New File command. (See Understanding bit depth.)
Choose a bit depth carefully, because it cannot be changed after you create a session. Ideally, you should work at the 32-bit level with fast systems. If your system performs slowly, try a lower bit depth.
Determines whether tracks are mixed down to a mono, stereo, or 5.1 Master track. (See Routing audio to buses, sends, and the Master track.)
Open existing audio files and multitrack mixes
The following file types open in the Multitrack Editor: Audition Session, Adobe Premiere Pro Sequence XML, Final Cut Pro XML Interchange, and OMF.
All other supported file types open in the Waveform Editor, including the audio portion of video files.
SES session files from Audition 3.0 and earlier are unsupported. If you have Audition 3.0, save sessions to XML format to open them in CS versions. Note, however, that older effects are excluded in CS6, effects and time-stretching are excluded in CS5.5.
If you open multiple files, Editor panel menu lets you choose which file to display
Append audio files to another (Audition CS6)
Append files with CD Track markers to quickly assemble audio and apply consistent processing.
If the selected files have a different sample rate, bit depth, or channel type than the open file, Audition converts the selected files to match the open file. For the best results, append files with the same sample type as the original file.
Import a file as raw data
If you can’t open a particular file, it may lack necessary header information that describes the sample type. To manually specify this information, import the file as raw data.
Should match the known rate of the file, if possible. For examples of common settings, see Understanding sample rate. Adobe Audition can import raw data with rates ranging from 1 to 10,000,000 Hz, but playback and recording are supported only between 6000 Hz and 192,000 Hz.
Specifies the data storage scheme for the file. If you are unsure what encoding the file uses, consult the supplier of the file, or the documentation for the application that created it. In many cases, trial and error might be necessary.
Specifies the numerical sequence for bytes of data. The Little-Endian method is common to WAV files, while the Big-Endian method is common to AIFF files. The Default Byte Order automatically applies the default for your system processor and is typically the best option.
Insert an audio file into a multitrack session
When you insert an audio file in the Multitrack Editor, the file becomes an audio clip on the selected track. If you insert several files at once, or a single file that’s longer than the space available on the selected track, Adobe Audition inserts new clips on the nearest empty tracks.
In CS6, drag ranges from the Markers panel to the Multitrack Editor to automatically convert them to clips.
Spot-insert a Broadcast Wave file into a session
When you insert a Broadcast Wave (BWF) file into a multitrack session, Adobe Audition can use the embedded timestamp to insert the file at a specific time. This is commonly called spot-inserting.
To view or edit the timestamp for a BWF clip, open the clip in the Waveform Editor, and then choose Window > Metadata. On the BWF tab, the timestamp value appears as the Time Reference.
