The documentation I'm providing is a bit thin at the moment. The GUI's are mostly self explanatory, but there are some surprises... try clicking on graphs to see what happens.GAS documentation
Each program should be unzipped in a separate directory. Before running a program, the Matlab default path should be set to the one you wish to run. A word of warning: most of the programs here require version 6.0 of Matlab to run properly.
common files - these files are the pitch detection "engine" used
in many of the above. My suggestion is to put them in a separate directory
and add it to the matlab default path.
FFT demo - just demonstrates the effect of windowing and
such on a periodic signal
LPC vocoder - let's you do LPC analysis/synthesis.
The pitch curve can be edited with your mouse!
Pitch detector - autocorrelation pitch detector. Click
on the signal to get the present window and it's autocorrelation.
Sinusoidal coder - quite complicated... try the various
options and click anywhere you can....
Spectrogram - a spectrogram that's also clickable - and
have a look at the LPC option
Two wav's - a male and female soundfile I often use. The
male - is in hebrew :-).
