[SciPy-user] Zero crossings

[Christopher Brown]

Thanks Sturla and J-Pascal,

SM> zc = numpy.where(numpy.sign(a[1:]) != numpy.sign(a[:-1]))

I want to estimate f0 based on zero crossings in recorded speech, and 
I've got something that looks pretty good for only a few hours of work.

Does anyone have any interest in this kind of thing?
