The Audacity Nyquist prompt is placed in the Audacity "Effect" menu which only can be activated if an Audacity audio track exists and at least a part of it marked or selected.

Load a Sound File

If you have a mono or stereo sound file available you can load it into Audacity via:

  • Audacity File menu > Import > Audio   or   Shift + Control + I

If you have no sound files available you can build your own mono or stereo tracks via the Audacity 'Generate' menu.

Create a Mono Track

Go to the Audacity "Generate" menu and choose "Tone". Leave everything as-is, just click "OK", a mono track will appear in the Audacity window.


Create a Stereo Track

1. Mark the whole mono track from above either by pressing "Ctrl+A" on the keyboard, or by clicking with the mouse into the track header, with taking care not to move the buttons or sliders, the whole track then will appear in a different color.

2. Go to the "Edit" menu and choose "Duplicate". A second, identical mono track will appear below the first one.

3. In the upper mono track, open the track menu by clicking on the small black triangle at the top of the track header and coose "Make stereo track". Both mono tracks then will get combined to a single stereo track.
