How to covert hummming into pitches? I am not sure if this question suits this site, but I want to convert humming into notes or relative values to analyse melodies, word of "Signal Processing" looks suit for this. I am planning to use Flash AS3, and Tortoise and Hare for Cycle Detection. I need very simple script implementation. All I want is find notes more easily with my bass. Is that possible? Or is there any frameworks that already makes this?
You can try using a Pitch Track for monophonic signal, you need track low pitches!

There is a wide range of algorithms to find Pitches in time domain (zero crossing, AMDF, YIN, MPM, ASDF, autocorrelation ....) or Frequency domain (shs, hps, cepstrum ....)

Each one of them possess advantages or disadvantages !

With the Pitch Track you can convert one frequency to note.

I never used Flash AS3 to DSP, one fast and easy way are the autocorrelation based algorithms.
