Creating a New Multichannel Audio File
You can create a new multichannel file and specify the number of channels and the
sample rate.
To open a new multichannel audio file:
1 Do one of the following:
 Choose File > New > Audio File (or press Command-Shift-N).
 Click New Audio File in the Toolbar.
2 Choose an option from the Channels pop-up menu:
 Mono
 Stereo
 Surround (5.1)
 Other
Note: If you choose Other, use the value slider to enter the number of channels for
the new audio file.
3 Enter a sample rate in the Sample Rate field or choose one from the pop-up menu.
4 Click OK.
Using Frequency Spectrum View
When you first open the File Editor, it shows the audio file in Waveform view. You can also
view and edit an audio file in Frequency Spectrum view. Frequency Spectrum view gives
you a way to find areas of significant frequency change that aren’t visible in a waveform.
Viewing an Audio File in Frequency Spectrum View
In Frequency Spectrum view, the display shows the frequency spectrum of each
channel of a stereo audio file on a scale from 0 Hertz (Hz) to half the sample rate of the
file. For example, for a 48 kHz audio file, the scale progresses from 0 Hz to 24 kHz.
