Not entirely sure if this question goes on this site, but I think it covers this one more than the others.
I need to record some audio of human speech and find the frequency of the audio at least 100 times a second, 1000 is better. I want the frequencies to be output somewhere in a list so that I can copy+paste them for another use, and maybe delete or mark them from the list so I don't lose track of where I am.
What (preferably free) software should I use?
Frequencies are a spectrum from 0Hz up to approximately 20kHz. To obtain spectra of sound samples, you will need an implementation of an FFT (Fast Fourier Transform) library.
For the application you are describing, you will need to use something like Matlab or Octave.
