� using this Hilbert, analytic signal thing for frequency detection works only for pure sinusoids (that are amplitude-modulated and/or frequency-modulated). �it's really unpredictable (i may be wrong, someone might have math that predicts) what the instantaneous phase coming out of this is for a complex signal going in. r b-j ---------------------------- Original Message ---------------------------- Subject: Re: [music-dsp] � 45� Hilbert transformer for pitch detection?
