LogSpectrum - Make number of octaves configurable

Open xaviliz opened this issue 3 years ago • 5 comments

Hi guys,

I was using LogSpectrum lately. I realize the output spectrum it is limited to 7 or 8 octaves.

acumulated_spectrum__Duke Jones_This Could Be (Chill Mix)

Do you know if there is some way to extract the LogSpectrum for all frequencies? It would be nice to cover the whole spectrum without discarding HF content or to providing n_octaves as a parameter.

Thanks in advance

This should be as easy as making _nOctave a parameter. Right now it is hardcoded. A pull-request is welcome.

yes, that would be nice. I will do a PR next week

Thanks! Not so much. It would be nice to assess it as spectral descriptor in different tasks.
