Coding

I have re-written a sound capture plugin - that can capture from 4 stereo lines (8 channels max) and rewrote all blend shape calculation functions.
I have tried to do it in a simple way and do things realy fast.

Ah yes, multichannel sound comes from USB 2.0 (480 Mbit/s) device capable of delivering 96kHz, but i am taking 44.1 only. Not that i would need this much for what i do with streams (8000 Hz would suffice)

When app was up and running, after all the characters were properly set, a sudden frame rate drop occured. Why ?

It seems that audio device completly slows down the computer.

Ah yes, did the proper material library for shaders. PS2.0
Diffuse,Phong,Blinn,Minnaert,Oren-Nayar, Ward,Schlick,Cook-Torrance.
Versions are: noTex,Tex,Bump,Environment+Bump

So shaders anyone ?
