Právě že ve FAQ na www.hydrogenaudio.org se k verzi 3.97 píše toto:
The --vbr-new switch enables the new VBR mode:
LAME will encode much faster compared to old/default vbr mode. Current knowledge qualitywise comparing vbr with --vbr-new is, that --vbr-new might even be better qualitywise than the default vbr mode, but there are also reports about artefact, which is worse in --vbr-new compared to default. The general impression is, that --vbr-new should be recommended over vbr-default. --vbr-new can be faster and at equal/better quality at same time, because it uses a different algorithm than old/default vbr mode.
A pak je tu tabulka:
The settings, presets are listed beginning with highest possible quality (-b 320) stepping down to lower qualities:
CODE
switch equals preset target kbit/s bitrate range kbit/s
-b 320 = --preset insane 320 320 CBR
-V 0 --vbr-new = --preset fast extreme 245 220…260
-V 0 = --preset extreme 245 220…260
-V 1 --vbr-new 225 200…250
-V 1 225 200…250
-V 2 --vbr-new = --preset fast standard 190 170…210
-V 2 = --preset standard 190 170…210
která je seřazena podle kvality a new je před old. Takže teďka těžko říct.
