Hi,
I got some suggestions for LAME. They're not too complicated (probably are
to implement, though), so here goes:
- LAME VBR doesn't encode the LSB (Least Significant Bit) correctly (as
described on http://privatewww.essex.ac.uk/~djmrob/mp3decoders/lsb.html) -
what exactly is causing this and how could it be fixed?
- A good suggestion, IMHO: freeformat VBR encoding up to 640 kbs - this
feature could be implemented through the -B switch (with additional values
of 384/448/512/640), which would default to 320, but could be set higher to
give a freeformat VBR. This would have the advantage that some parts which
are too difficult to compress even with 320 kbs could use even higher
bitrates which would improve the quality of those frames. I'm sure not many
people would mind a freeformat VBR MP3 if it would mean a nice improvement
in quality without having the file bloated like with freeformat CBR.
- An engine which would analyze the source data and find out which mode
for -X would be best to use for compression (I have to admit though, that I
am not too familiar with the -Xx settings - if someone could please explain
these modes (or point me to a document which explains them), I'd be very
grateful)
That's all for now. LAME is the best MP3 encoder out there - better than FhG
even - and I am certain it will improve much more, considering the great
people that are working on it right now. Keep up the good work!
Thanks!
