What do you want exactly ?

I want to overlap an audio signal with a sound generated by five formants. These formants will be generated by a bank of filtered white noise. The filters will use for this purpose will be bandpass filters, which need the frequency and Q parameters of the original signal to create a smooth overlap .

Compute the standard deviation of the frequency histogram (spectrogram) ?

Compute the frequency bounds within which 95 % of the energy lies ?

Compute the max frequency minus the min frequency ?

Something else related to that ?

Thank you.
