I actually anticipated this for quite some while, but thought I had
figured it out using some random source of input. I can't reproduce my
findings (or even my search), so thanks. :-)

Is there a way to specify infinity? Actually, why not let it go
infinitely by default, like the sine audio source does?

As Nicolas pointed out, AV_OPT_TYPE_DURATION is more generic for
durations.

I second the notion for other colors of sound (pink).

Question: If I use two of these, will they be seeded identically or
independantly and randomly? (Like for merging to a left and right
channel, and not achieving a mono sound.)

Thanks,
Moritz
