can someone email me a list of special spots in quality settings, or point me to a website that tells these settings? i know i may be confusing, i'm talking about like the jump between -q4.99 and -q5 because of the whole lossy/lossless channel coupling, and filesize jump...i also know somewhere above there there is different high and low frequency cutoffs, and a point where there IS NO frequency cutoff, could someone tell me these? i'm just curious...

4.99->5 is the only jump I am aware of. When RC3 was released there was a whole bunch of graphs on various wevsites showing average bitrate vs quality level for different input. The most notable thing in the graph was the jump at 5, other than that it was a reasonably continuous, upward sloping graph.

Quoting from Alan McDonald's mail of March 11th 2002:>From vorbis/lib/modes/psych_44.h:/* lowpass **************/ static double _psy_lowpass_44[11]={ 15.1,15.8,16.5,17.9,20.5,48.,999.,999.,999.,999.,999. }; o q0=15.1, q1=15.8, q2=16.5, q3=17.9, etc... <p>To answer your question, no lowpassing happens at q 6 and higher, while anything >= q 4 doesn't have noticeable lowpassing. <p>Moritz --- >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.
