I think we first need to examine the waveform to determine if it is fairly even. (Hopefully, it will just be a "lah" sound from the microphone.
:Maybe find the range of the frequencies used, and hopefully that will fall into one of our solfa bands. If not, then it might be a just a case of deciding between two notes. [[User:Markhobley|Markhobley]] 10:55, 13 July 2011 (UTC)
If the given waveform is fairly even, then I am thinking that we could take the modal result of the frequencies used throughout the given waveform and use the mathematical mode for our average, or if the results do not produce a mode, then we take a median.
:This would really be the modal result of bands of frequencies within the waveform. [[User:Markhobley|Markhobley]] 10:55, 13 July 2011 (UTC)
Others have suggested Fast Fourier Transformation and Enhanced Autocorrelation functions to determine the pitch.
