...n at the CVS head, last changed around 11/9 or so). 1. I'm thinking that this program is basically supposed to solve the VQ design problem, as documented on 'http://data-compression.com/vq.html' (with some variations for vorbis). In that problem, the goal is to choose the codevectors to minimize average distortion (average distance between each training vector and its associated codevector). This measure, or something similar, is given in the residuevqtrain output as 'metric error'. In the run I did, though, the value of metric error actually *increas...

...ry bitstream. Can we, for example, change the volume of the whole sound by scaling the vectors in the codebook? (My guess is that this wouldn't be enough, as we have to scale the floor of every frame too). That would be cool. A similar question about equalizing/filtering by playing with the codevectors. A somewhat unrelated question: how different is the MP3 decoding from Vorbis? Specifically, can we create a lossless mapping utility from MP3 to Vorbis without re-encoding (using a specialized for this codebook maybe - although MP3 doesn't use vq). -- Beni Cherniavsky <cben@crosswinds...
