[Audacity-nyquist] Processing individual samples

[Jean Z. <jz...@fr...>]

Hi all,

I've been toying with Audacity sources for a while. For effects, C is
fast (good) but needs to be compiled and linked in Audacity (bad, not
distributable). Ok, let's do it in Nyquist - I'm a total newbie in
Lisp but beginning to grasp a few concepts. What I want will be slow,
in fact I'm pretty sure it will take a looooong time to execute, but
this is not a real issue to me.

I'm looking for a way to alter individual samples based on a given
algorithm. In fact, I'd like to know if there's a canonical way to do
it, something like a standard loop where I could insert whatever math
function(s) I need. I suppose snd-fetch could be involved, as well as
snd-from-array, all within the loop. Is it the right direction? Am I
missing something?

Thanks in advance for your feedback and suggestions.
