has been discarded (and therefore the original signal can only be reconstructed from the coefficients, not from the pixels). The coloring in the demo is made by constructing a separate spectrogram for each stereo channel or track, tinting them differently and adding them tog

x27;m actually not that familiar with traditional STFTs and COLA, but as far as I can tell, the STFT is a special case of the NSGT and the same dual frame techniques should apply. -- Andreas Gustafsson, g...@waxingwave.com ___ dupswapdrop: music-dsp mailing list music-dsp@music.columbia.edu https://lists.columbia.edu/mailman/listinfo/music-dsp
