RE: [Audacity-nyquist] Anti-aliasing Finite Impulse Response (FIR) filter (fwd)

[Alex S. B. <ale...@al...>]

Gary,

Besides using the stand-alone Nyquist, you can also write compiled plug ins for
Audacity or for Nyquist itself. In that way you could use Nyquist as a
prototyping language and then write a compilable version in C or some other
language.

Audacity supports LADSPA and VST plug-ins. See
http://audacity.sourceforge.net/download/plugins
for details. I do not know how to write them, but I understand these plug-ins
can be authored and compiled.

The full Nyquist documentation, which comes with the standalone package,
includes instructions on how to write plug-ins for Nyquist. That might be the
best of both worlds for you. You can read more in Appendix 1:
http://www.cs.cmu.edu/~rbd/doc/nyquist/part14.html#139

If you review the whole documentation set, you will find other ways to link
Nyquist into other libraries. Here is the main on-line documentation group:
http://www.cs.cmu.edu/~rbd/doc/nyquist/root.html

I see ways to call C routines, if you need to.

I emphasize that I have never done these extensions myself, and some may not
work with Audacity's version of Nyquist, but they are tools to try out.
