some more Spec questions
...or is used to map an element of the final-floor vector to a bark-scale frequency, is this correct ? - The formulas for p and q make use of omega, but there's nothing in the spec about omega... How is omega related to [i] or to ([map] element [i]) ? I can only assume.... omega = map[i]/bark_map_size ? <p>thanks in advance, Sebastian --- >8 ---- List archives: http://www.xiph.org/archives/ Ogg project homepage: http://www.xiph.org/ogg/ To unsubscribe from this list, send a message to 'vorbis-request@xiph.org' containing only the word 'unsubscribe' in the body.

Vorbis spec bugs
...hesis-stuff: there's a nice image with bark(x) = atan()... and stuff Question: What is [n] in the map(i)-iteration ? I find it a bit confusing because 'n' is used to describe the length of the spectral-vector to be feed into the MDCT in the paragraph above. But the value of bark_map_size seem to make more sense in this context. (?) Also, i miss the usage of [i] within the formulas for p and q. I assume cos(w) = cos(i*PI/n). Is this correct ? <p><p>thanks for help, Sebastian --- >8 ---- List archives: http://www.xiph.org/archives/ Ogg project homepage: http:...
