Opening audio files in Edit View
Create a new, blank audio file
The File > New command creates blank audio files, which are perfect for recording new audio or combining pasted
audio.
1 In Edit View, choose File > New.

data” on page 76.)
2 In the New Waveform dialog box, set the following options, and click OK:
Sample Rate Determines the range of frequencies that can be reproduced. To reproduce a given frequency, the
sample rate must be at least twice that frequency. (See “Sample rate” on page 10.)
Channels Determines if the waveform is mono or stereo.
• Mono Creates a waveform with just one channel of audio information. This option works well for a voice-only
recording.
• Stereo Creates a two-channel waveform with separate right and left channels. This option is usually best for a
music recording. However, because stereo waveforms contain twice as much data, they consume twice the storage
space of mono waveforms.
Resolution Determinestherangeofamplitudelevelsthatcanbereproduced.The32-bitlevelisbestwhileyouwork
in Adobe Audition. You can convert down for output later, if necessary. (See “Change the bit depth of a file” on
page 99.)
Note: If you have an older sound card that can’t play 32-bit files properly, you can use a lower bit depth for playback,
without lowering the bit depth of a file. To check the capabilities of your sound card, choose Edit > Audio Hardware
Setup, select the sound card under Audio Driver, and click Control Panel. For information about the available options,
see your sound card documentation.
Open existing audio files
In Edit View, you can open audio from a variety of audio file formats, including MP3, WAV, and AIFF. You can also
open the audio portion of video files in AVI, MPEG, MOV, or WMV format.
