I am using the tkSnack library to estimate the frequency from a sound file. The pitch seems to drop down an octave at 400 Hertz. For example A~440 Hertz comes out at 220 Hertz. When I use the maxpitch and minpitch options to limit the response to say 380 - 460 the result is all zeros.
Any ideas on how I can estimate the pitch of a sound up to 880 Hertz (with tkSnack or not)? Thanks Justin Shaw -- http://mail.python.org/mailman/listinfo/python-list
