[请教]求razorlame VBR最好的参数|『影音数码技术学习交流』 - 『漫游』酷论坛

说明书里面抄的@@..^^ -V好像只适用于VBR呢^^

VBR modes

--preset extreme
If you have extremely good hearing and similar equipment, this preset will provide slightly higher quality than the "standard" mode.
The resulting bitrate should be in the 200-240kbps range, according to music complexity.

CBR 320kbps
--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. This preset is the highest preset quality available.

* -V 0...9 VBR quality setting
Enable VBR (Variable BitRate) and specifies the value of VBR quality.
default=4
0=highest quality.

* -q 0..9 algorithm quality selection
Bitrate is of course the main influence on quality. The higher the bitrate, the higher the quality. But for a given bitrate, we have a choice of algorithms to determine the best scalefactors and huffman encoding (noise shaping).

-q 0: use slowest & best possible version of all algorithms. -q 0 and -q 1 are slow and may not produce significantly higher quality.
-q 2: recommended. Same as -h.
-q 5: default value. Good speed, reasonable quality.
-q 7: same as -f. Very fast, ok quality. (psycho acoustics are used for pre-echo & M/S, but no noise shaping is done.
-q 9: disables almost all algorithms including psy-model. poor quality.

最初由 Siki 发布

这个预设值不是最好质量. INCENT..那个才是 (那个单词的意思是"疯子")
另外,即使用了INCENT 还需要补充上 -q 0 -V 0 才能称得上MP3的封顶设置.

跟CVD是有很大区别的,只要你一直听CD习惯了,然后听MP3你就知道.

还有就是音箱要好

INCENT那个是cbr模式下的峰值编码方式，用到mp3的峰值320K，看清楚楼主是问vbr，而且用cbr峰值320K直压不太明智吧。
