notes

These M-files implement a few reverberation algorithms (based on Schroeder's and Moorer's
algorithms). Each of the M-files include a short description.

There are 5 M-files that implement reverberation. They are:

- schroeder1.m
- schroeder2.m
- schroeder3.m
- moorer.m
- stereoverb.m

The remaining 8 M-files implement filters, delay lines etc. Most of these are used in the
above M-files. They can also be used as building blocks for other reverberation
algorithms.

StereoVerb is the name of an old car stereo "enhancer" from way back. I was just trying to find
it's roots.

There is another allpass filter transfer function.
      -g+Z^(-m)
H(z)=------------
      1-gZ^(-m)

g is the attenuation
m is the number of delay (in sampel)

This allpass will give exponential decay impulse response, compare to your allpass that give
half sinc decay impulse response.
