Viewing an Audio File in Spectrum View
When you first open the Waveform Editor, it shows the audio file in Waveform view. You
can also view and edit an audio file in Spectrum view. In 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.
To view an audio file in Spectrum view:
m Click the Spectrum View button above the right corner of the Global Waveform view.
The display changes to show the audio file’s frequency spectrum.
You can select parts of the audio file, apply actions, and edit the audio file in Spectrum
view in the same way as in Waveform view. You can also change the Spectrum view
display to show the frequency spectrum linearly or logarithmically, use different
window functions, and change the number of samples used to calculate the view.
