Which is the part that you are frustrated by? Achieving the same loudness or exporting as M4A?

Normalize can be used in a Chain to make the peak amplitude the same in all files. (As koz mentioned, just because audio files have the same peak (maximum) amplitude does not necessarily mean they will sound the same "loudness"). Exporting M4A is not supported in Chains, but if you export ...

Here you go. If you open this in a plain text editor you will see what I've changed. Basically just changing the midi note control so that it has a frequency range, then removing the "step-to-hz" command so that the generator uses frequency (in Hz) rather than "steps" (MIDI note ...

The more I think about this, the more I arrive at the thought that the Spectral Selection Toolbar is not really such a good idea. It was a quick and easy way to add VI accessibility, but the concept has some serious flaws that I don't see solutions to. The primary problem is with multiple tracks. Sa...

You've not picked an easy project for a first project. One way to accomplish the task is with the function "snd-compose" http://www.cs.cmu.edu/~rbd/doc/nyquist/part8.html#index687 An example of using snd-compose can be found in "turntablewarp-ms". Unfortunately this is a very old...

I'm not able to reproduce the issue. Is it repeatable for you? If so, could you make a ZIP archive of the project (including the AUP file and its _data folder) and upload it somewhere, then post a link to it. There's some suggestions of free file sharing sites near the bottom of this post: http://fo...

There is no version "2.1". Look in "Help > About Audacity" for the full version number.
Where did you obtain this version of Audacity?

So, Isn't there a way to do a frequency inversion in Audacity? Yes, you would do it with Nyquist, but it's not an easy project. Below is a link to the "Nyquist FFT and Inverse FFT Tutorial" from the Nyquist documentation. To do frequency inversion, take the FFT of the sound. For each FFT ...

It's not easy to do in Nyquist. That script is only using Python to tell SoX what to do. SoX is an advance command line audio editor and processor - a bit like a command line version of Audacity. Nyquist in Audacity is not able to access external libraries, so it can't use SoX, which means that to a...
