請問 vbr-old 與 vbr-new 有什麼差別
壓MP3選擇哪一種比較好？ ?_?
VBR方法疑問...
版主: DearHoney
以下是CDex的HELP檔的說明
＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝
Disabled: Don't use VBR; instead encodie with a Constant Bit Rate (CBR)
VBR-Default: Use the default VBR method (currently set to VBR-MTRH)
VBR-Old: LAME's first functional approach, based on masking, bisection in the bit domain.
VBR-New: LAME's second approach, based on masking and direct noise allocation.
VBR-MTRH: a combination of old and new (VBR) routines
VBR-ABR: The Average Bit Rate (ABR) setting, the encoding principle is similar to what AAC uses as VBR encoding, it is based on perceptual entropy, but more like CBR than VBR. When you select the ABR option in the VBR Settings box, the ABR edit box will be enabled. In this edit box you can specify the target average bit rate. Of course, a larger bit rate will yield generally better-sounding (but larger) MP3 files.
