Re: Autocorrelation pitch detection

The first, simple, method proposed by Paul Boersma is implemented in MIRtoolbox, and is available as default when calling mirautocor. You can toggle this option off by using the mirautocor('NormalWindow', 'off'), and you can also choose a different window apart from 'hanning'. More details in p. 52 of the MIRtoolbox User's Guide:

The second, complex, method is not implemented in MIRtoolbox. But it could be very nice to integrate it. So if there is some code available that could be integrated in the toolbox (with acknowledgments), that would be great indeed.

MIRtoolbox itself is available as a free Matlab toolbox at the following address:
