I'll have to go find my copy, but I believe there are several algorithms
for all sorts of processors in Chamberlain's book "Musical Applications
of Microprocessors".
Another resource would be the app notes for any of the DSP cores, both
TI and Motorola used to publish source code for building blocks such as
filters and compressors and even a reverb I think.
The one that got me started was a phase vocoder in the back of one of
the AES anthologies. I'll try to find that one too.
Oh, and there was a development kit that I think Analog Devices sold for
one of their chips that came with a fantastic cook book.
There are certainly others, but those come to mind first. Well, those,
and of course Google<G>!

Hello,
I am trying to get started with developing audio units. I have put together a basic audio unit that does nothing (just lets the samples pass thru). I now want for it to do *something*. I looked over the source code for the tremolo filter on Apple's website and I think that I understand how it works. However, I am interested in equalizers and would really like to develop one.
Are there any suggestions for getting started, or even a basic description of the algorithm that I will need?
A simple eq seems to be fairly standard in all DSPs.
Even if somebody could point me to source code for a single band pass filter that would be greatly appreciated.
I was hoping to find source code for AUBandPass, but that does not seem to be available anywhere.
If there any recommended books, that would be helpful too.
Thanks,
Chaim
