Sound Card Spectrum Toggle


Macro: Spect

You can toggle Spectrum display mode via the toolbar Spectrum button or ALT+S. It is automatically toggled off if Spectrogram / Pitch Track (Sgram/PT) is toggled on.

If neither Spectrum nor Spectrogram / Pitch Track is active, the waveform is displayed.

The thin button below the toolbar Spectrum button opens the Spectrum Control Dialog. You can also use CTRL+S, or ALT+E, S from the Edit menu.


Macro Notes:

Spect=1 activates Spectrum mode, Spect=0 restores waveform display mode, and Spect=x toggles between them.
