understanding vorbis
...extend that patch. Right now I study
lib/envelope.c. The method _ve_amp() returns a combination of flags
1|2|4. 1 seems to indicate that some maximum has been exceeded and 2
the same for the minimum. Do you have suggestion for symbolc constants
here (aka #defines). Any details what this pre/postecho is about?
The result is used in _ve_envelope_search() to set some marks
(ve->mark). Then there is some search in the mark-vector and based on
the vorbis switches between the two mdct parameter sets (small/large).
Thanks for any insight in advance.
