The first thing that comes to my mind is: Now how do we design some frequency transform that provides better results than human hearing? I honestly don't know. FFT has been the de-facto frequency transform in my head for far too long. My own attempt to hack around with wavelets never gave me better time/frequency resolution than your typical STFT. What other options do we have?

What other options do we have? Parallel bandpass filters (PEAQ Advanced). More accurate, very slow. Wavelets on the MDCT coefficients (Opus). Fast, can switch the T/F tradeoff depending on the signal. The ear works more like the parallel filters setup. |
