White noise:

Most of the Nyquist plug-in "Property Lists" should also work.

Are there any additional features that you think would be useful / interesting?

There are also some constants available:

pi = 3.14159265...
t = true
nil = false
*sound-srate* = the track sample rate
*control-srate* = 1/20th of the track sample rate
dur = the specified duration in seconds

If you want a fractional (floating point) result, then either one of the numbers must be a floating point number, or you must explicitly convert the number to floating point: (setf *float-fo...

provided that the expression returns a number (for the sample value).

Tan(PI/2) is "undefined". It is neither +∞ or -∞. It is "not a number" (a "NaN"), and that is the problem. Audacity does not handle NaNs very well (but better now than in older releases). It's the NaNs that cause the corruption. When exported, the NaNs are replaced by I...

I am fooled by this every time I use it for multi-track recording and I think this is something that should be addressed in Audacity features. In fact I can't think of a multi-track use case where *removing* the time alignment makes sense but I imagine there must be one? As Gale hinted, this is one...
