Audacity Forum

Is there any way I can automate this process with Audacity? Yes, you need to apply a "Noise Gate". A Noise Gate is an effect that "lets through" sounds that are above a certain threshold level, until the sound level (amplitude) drops below the specified level. When the sound lev...

I've just downloaded the most recent version and tested it, just to make sure that it hadn't been corrupted when uploading to the forum. It works fine. The "Random" setting does not work, but that does not work in the original code that you posted (because it isn't implemented). All the ot...

Gramophone warp & wow are effectively changes in speed which change the pitch, so theoretically correctable by changing the time-track in Audacity into something sinusoidal, a tedious 78 times per minute. Michael Kazmierski says that he is using a screen reader, and unfortunately time tracks ar...

If "phase" is set to 180 or minus 180 degrees, then triangle vibrato starts at the high end of the pitch bend. I forgot, screen readers usually show sliders with a range of 0 to 100, at least that's what NVDA does with Nyquist plug-ins. So to start triangle vibrato at the high end of the ...

If I select another wave, there is just an OK button with no dialog text. That sounds very odd. I don't have Jaws, but I can check what happens with NVDA. I might be able to isolate the problem in this section of coding. I very much doubt that it is related to that part of the code. The only parts ...

I very much doubt that a warped record really does create triangular modulation, though I can imagine it being a bit more "triangular" than a perfect sine tone. Ideally what you need is to track the pitch deviation and then apply an inverse "map" of that deviation, but that is ve...

First of all there is only one speed control Your record player speeds up / slows down? I expected a 78 to rotate at 78 RPM. To re-enable the second speed control, delete the first semicolon from the line: ;;control fspeed "Final speed (Hz)" real "" 12 0 20000 so that it is: ;co...

Try this modified version. I've changed the name to "Vibrato Phase...", set the control ranges closer to your settings, and added a phase control.

Your file "afsk_generate.ny" is not valid Nyquist code. There are very many errors in that code. It should not be a surprise that attempting to run invalid code produces errors.
