There have been a number of issues with Nyquist. Nyquist is a programming language that is built into Audacity. "Click Track" is accomplished using Nyquist (it is a Nyquist script). The Audacity developers are aware of issues with Click Track and it has now been fixed. The latest version (...

"Clipping" is when the top and/or bottom of the waveform get chopped off - it is a nasty kind of distortion that occurs when you try to amplify a sound higher than 0dB. In digital audio, "0dB" is "full scale" - there is no way to increase a signal beyond 0dB. The actual...

Which tutorial is recommended. All/any of them. Just find one that looks interesting and try working through it - you will learn a lot about using Audacity by working through any of them. The Audacity 1.2 tutorials are probably the easiest to start with: http://audacityteam.org/manual-1.2/tutorials...

"lowpass8" is a low-pass filter "highpass8 is a high-pass filter (both are documented in the manual). (setq note (scale amp (highpass8 (lowpass8 note freq) freq))))) Working from the innermost "()" (lowpass8 note freq) .... "note" is a sound. This is processed thro...

Since it was first posted, I uninstalled then reinstalled Audacity & now it seems to work just fine. Although I'm still unclear as to why Audacity defaults to Windows Sound Mapper & if I should leave it set to that even though I'm actually recording through a Tascam US-122L interface & ...

That's the clue we were waiting for.

I shouldn't get too hung up about the ".26" . the rotational speed of "78's" was rather approximate as clockwork mechanisms were widely used right up into the 1940's. For "ageing" the recording, the main things are to reduce the frequency response (use a low and high pa...

There are some good tutorials in the Audacity wiki (see "Tutorials" link at top of page).

Here is a Nyquist plug-in that will create a text file with the sample values for the left and right channels of a stereo track. Audacity 1.3 is required. I don't know if this will be any good for Matlab (it's not exactly in the form that you are asking for), but it gives you a text print out of the...
