[DSP-10] alt-V

[Courtney Duncan]

Alt-V is a great tool for ... many things, like finding a quiet 
direction to listen to.  I was wondering if it was possible to also 
play the regular audio and Alt-V tone at the same time.  I wouldn't 
want to sit and monitor for hours on end like that, but can imagine 
uses for that too.

It seems like it's about an octave in pitch for every 10 dB of noise. 
Is that about right?
