WAV functions
To: Daryl van den Brink
Do you know a good algorithm to combine two or more WAV files?
I've written an amusement for myself. Its a little application that I can
use to write music with. It works on the principle of creating 'voice'
tracks and then combining them into the final WAV file. The current
algorithm I use sort of works, but it has the side-effect of diminishing
the volume of the sound. Also, when working with lots of tracks, some
distortions are introduced.
In fact I've tried a few algorithms but none have really worked well. The
ones that have given me the most promising results have been ...
a) Find the geometric mean of the corresponding sample values.
b) Find the arthimetric mean of the corresponding sample values.
c) Find the geometric mean of the absolute value of the corresponding
sample values.
But I'm thinking that I really need to use the delta between adjacent
samples instead. I haven't tried this yet because I really don't know
enough about the subject.
I'd post the code but its not ready for serious reviewing yet - most is
very experimental.
