True. But this is of no concern for my program. It doesn't try to 
emulate psycho-acoustics of human perception. IMO that would be a 
problem of acoustic engineers.

My program just tries to translate sounds in virtal space to audio track 
of one, two, six or whatever else number of channels as best as it can 
doing it automatically.

The project was started when the amount of sounds in a video ("foley" 
sounds, background effects and such) was becoming more than I wanted to 
deal with manually with a DAW. And I couldn't find any FOSS alternative.

If it is of interest to anyone, program (non-working draft of program) 
is located here.
