21 Chapter 4: Importing, recording, and playing audio Creating and opening files Note: Some features in the Windows version of Adobe Audition 3.0 are not available in CS5.5. Examples include some file formats and effects, CD burning, MIDI, the metronome, clip grouping and time stretching, and control surface support. For a complete list, see Adobe Audition 3.0 features replaced or not implemented in CS5.5. Create a new, blank audio file New, blank audio files are perfect for recording new audio or combining pasted audio. 1 Choose File > New > Audio File. To quickly create a file from selected audio in an open file, choose Edit > Copy To New. (See "Copy or cut audio data" on page 42.) 2 Enter a filename, and set the following options: Sample Rate 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" on page 5.) Channels Determines if the waveform is mono, stereo, 5.1 surround. For voice-only recordings, the mono option is a good choice that results in quicker processing and smaller files. Bit Depth Determines the amplitude range of the file. The 32-bit level provides maximum processing flexibility in Adobe Audition. For compatibility with common applications, however, convert to a lower bit depth when editing is complete. (See "Understanding bit depth" on page 6 and "Change the bit depth of a file" on page 54.) 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). 1 Choose File > New > Multitrack Session. 2 Enter a filename and location, and set the following options: Sample Rate 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" on page 5.) Note: 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. Last updated 2/16/2012

playing audio
Creating and opening files
Note:
Some features in the Windows version of Adobe Audition 3.0 are not available in CS5.5. Examples include some
file formats and effects, CD burning, MIDI, the metronome, clip grouping and time stretching, and control surface
support. For a complete list, see

Create a new, blank audio file
New, blank audio files are perfect for recording new audio or combining pasted audio.
1
Choose File
> New > Audio File.
To quickly create a file from selected audio in an open file, choose Edit
> Copy To New. (See “
Copy or cut audio data
”
on page
42.)
2
Enter a filename, and set the following options:
Sample Rate
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
” on page
5.)
Channels
Determines if the waveform is mono, stereo, 5.1 surround.
For voice-only recordings, the mono option is a good choice that results in quicker processing and smaller files.
Bit Depth
Determines the amplitude range of the file. The 32-bit level provides maximum processing flexibility in
Adobe Audition. For compatibility with common applications, however, convert to a lower bit depth when editing is
complete. (See “
Understanding bit depth
” on page
6 and “
Change the bit depth of a file
” on page
54.)
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).

Sample Rate
Determines the frequency range of the session. To reproduce a given frequency, the sample rate must be
at least twice that frequency. (See “

Note:
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.
