Thanks for you help Gabreil, I have produced some outputs, but cannot be totally sure that they are correct.

These are the things I want to output (if possible) from the psychoacoustic analysis:

-Spectrum of Audio (fft)
-Energy in perceptual domain
-Spread energy in perceptual domain
-Tonality Index
-Masking Threshold
-Threshold and Absolute Threshold

Could you clarify with me of their whereabouts in the code please?

Also, if I was to provide LAME.exe with only 1152 PCM samples (1 audio frame) at a time, would the psycho analysis for the above elements give me plots that I can interrupt sensibly frame by frame?

As this is rather Lame-centric, would you mind using one of the two Lame mailing lists?

i dont mind using a mailing list, but I will only be posting questions for about another two weeks, then my degree will have ended. I have posted a subsription request nevertheless.

Gabriel, how long does one normally wait before they expect a reply from your mailing list?
