Lame. And anything that uses lame.
(always with -q 0 which is due to a broken implementation of lame. It
allows you to do a speed vs. quality tradeoff for encoding. -q controls
the psychoacoustic. 0 == best, 9 == worst. Ever had a 320 kbs mp3 that
sounds utter crap? this is the reason. )
-m j for joint stereo
Do fex, say we want VBR, scaling between 32 and 320 with a quality
threshold :
lame -m j -q 0 -v -b 32 -B 320 -V 2
-b == lower threshold
-B == upper threshold
-V == quality pivot point. ( compare -q in oggenc )
or you can use the highest possible with their included preset :
( I don't recommend CBR. And ABR at 320 is useless because mp3 doesn't
support higher values )
For CBR 320kbps (highest quality possible from
the --preset switches):
--preset insane
This preset will usually be overkill for most people and most
situations, but if you must have the absolute highest quality with
no regard to filesize, this is the way to go.
Personally I recommend -V 2 or 3 or thereabouts.. Experiment with a
track or five and see what you like.
For ogg encoding, its even simpler, and produces overall better quality
(see other thread about ogg quality and encoding ).
oggenc -b 320 <filename>
Will produce an abr file with 320 kbps.. Not particularly perfect.
for a Variable quality threshold, simply do :
oggenc -q 8.5 <filename>
-q is the quality designator / tradeoff /pivot. ( -V with lame)
-1 is worst, 10 max.
I usually use 8, which gives an average bitrate of around 250 kbps
