Hi all,
I've noticed that some MP3 encoders (notably some versions of FhG) offer
"non-standard" bitrates without the use of free format. They do this by
alternating between the two closest bitrates. e.g. I can use
mp3enc -if foo.wav -of foo.mp3 -br 110000 -qual 6
producing an MP3 that uses 112kbps most of the time, dropping to 96kbps
regularly to reduce the average bitrate to 110kbps. It would seem that this
could be done without too much discontinuity in bits-per-frame by using the
bit reservoir to absorb the changes.
Would this feature be quite easy to add to LAME? I've found it quite useful
in making MP3s "just fit" a particular medium, e.g. compressing 14 60 minute
CDs at 110kbps to almost exactly fill a single CDR. (The BBC dramatization
of Lord of the Rings, for those wondering :)
