Hi all,
In short:
Where can i get alogorithms for pitch modification that i can use with
the 'audio unit effect' template?
Where can i get info on the different files and how they work in the
'audio unit effect' template?
And for my own interest; how do the values in the ~kernel::process()
translate to sound?
In long:
I want to get stuck into AU developement but i haven't had much
experience in programming or DSP (I've dabbled in C++, C, Objective-C
and a few other things). I plan on creating a pitch control plugin to
use with Garageband so that i can set my normal electric guitar down a
full octave and play it live like a bass guitar. The plugins AUPitch
and Vocal Transformer suffer from too high latency so i can't practice
anything. I've found the sites www.dspdimesnion.com and
www.dspguide.com so i have some material to get the DSP algortihms
from. Does anyone know of some better resources for Pitch
shifting/scaling?
I wanted to build the plugin from scratch using a guide or something,
but i couldn't find any. I've downloaded the apple templates and setup
one without the gain parameter, so it is just a simple out = in plugin
that i have no idea about. Does anybody know where i can get info on
what the files do and what the code inside them does, and more
importantly, what sort of data is the ~kernel::process() dealing with,
i.e. can you tell me about the values that are in inSourceP and
sourceP ?
Thanks alot for any replies
DKR
