So, I would like to have mp3 files close to 192 kbps. I listen mostly metal (various types - heavy, power, black, ...) and --alt-preset standard seems to create mostly bitrates of 200-250 (tested with several albums). I consider this to be too high, how should I create the files to get lower rates? Should I use ABR with --alt-preset [rate] or maybe some VBR command line (for example, edited -r3mix), using -V[n] to adjust the bitrates? Any suggestions?

when I use -alt-preset standard -b96 -Y --lowpass 17.5, it got a following warning msg.... *** WARNING *** the meaning of the experimental -Y has changed! now it tells LAME to ignore sfb21 noise shaping (VBR) I am not really sure how sfb21 noise shaping works, could someone please explain that to me? sfb21 = the band containing all frequencies above 16khz, in mp3. By using -Y, and disabling noise shaping in sfb21, it has the effect I specified... where it will not "go out of it's way" to encode this material if it requires a signficant jump in bitrate. QUOTE [b]Also by using the lowpass would it have any effect on the determination of bits in joint stereo and nspsytune? Probably not. The chances that the frequencies beyond 16khz could have a significant effect here is extremely slim I think. QUOTE What about and the -V3 switch, would it have any effect on the determination of bits in joint stereo and nspsytune OR conflict with the internal switch of alt-preset? Yes. The -V switches control the global adjustments to masking in LAME, so it would have an effect here. It would also break some of the tunings, but only in the sense that the thresholds would now be "out of whack". |
