Re: Standard Scale Modification Algorithm


This implementation :

Implements WSOLA -> As long as you use the version 2.8, you will have 
access to a time and frequency domain implementation. The frequency domain 
version is not 100%, however the time domain implementation is accurate 
(from memory) although slow ... the time domain implementation is really 
very good quality.

Download version 2.8 as it has the time domain implementation in it and 
ready to compile. You can copy the time window processing from this for 
your Matlab version ... if you do, please reference the original 

You will want to compile and run version 1 the following :

	g++ -O3 -lsndfile WSOLATest.v1.C -o WSOLA.v1

You can try version 2 but from this release it is not well implemented.
You will need libsndfile to compile as well ...

good luck if you choose this path.
