Hi Ricky,
Boids has been around for a long time and I'm certain it's been
used quite a few times in electroacoustic compositions - in fact, I seem to
remember one of our students on the Music Technology course here at York
doing so. Trouble is, I'm darned if I can remember his or her name (which
will be no surprise to anyone who's been on that course - my apologies to
the person concerned if they are reading this :-). Your best bet would be
to look through the Proceedings of the ICMC from around '87 and maybe the
Computer Music Journal.
I'm not sure what you mean by "...difficult to scale in terms of
distance". Are you referring to the mapping of the notional distances in
the boid simulation to the things which we use perceptually to deduce the
distance of a sound source? That's opening up an interesting can of worms!
Do a search in the archives for "giant geese" to see the fun we had talking
(arguing) about it last time. A lot will depend on wether the sound sources
are "familiar" or not - we can easily tell that a thunder storm (or a jet) is
distant or nearby because we are familiar with them as "perceptual objects"
and can construe them within the acoustic space we are listening in but
with constructed sounds that we are not familiar with we are stuck with
"immediate" (and to some extent, unreliable) cues like direct to
reverberant ratios, the pattern of early reflections, HF rolloff and maybe
distortion (loud sounds have distortion which increases with distance). If
he's currently on the list, I suspect Peter Lennox will jump in here and
tell me I've got it all wrong :-).
Anyway, I'm sure much/all of this is old news for you but I had to have
something to occupy a Sunday morning whilst waiting for the croissants to
warm up ....
All the best....
Dave
