Re: Tonal component detection

MATLAB implementation of the model that you're referring to can be found here:


MPEG for Matlab
Personal webpage of Fabien Petitcolas

And I think it should be easy to modify the tonality detection like the way you want it to be.

Dear auditory list members,

in the psychoacoustic model 1 of ISO/IEC 11172-3 (the one used for MPEG Layer I/II) a tonal component is detected as being local maximum and for at least 7 dB above it's largest neighbour.
Do you know of any publicly described tonal component detection where a tonal component is detected by comparing a local maximum with the average of the neighbours (i.e. comparing it to the spectral envelope)?
