I've encountered a sample that fulminates lame at any preset ( and I mean ANY, even --alt-preset insane).
http://www.terra.es/personal4/jas00010/fil...we32-20sec.flac (try http://jaz.project-psy.com/files/awe32-20sec.flac if the other one doesn't work) The sample comes from a self-made song (with virtual instruments), where I use chorusing. LAME produces noise in there. --alt-preset insane is nearly acceptable, but can be ABX'd (haven't tried to). Using --alt-preset standard, the noise is more hearable, and I'm sure that anyone can hear it with -b 128 Note: I used Headphones, because it's at night. Maybe with speakers the noise is not as evident. (As a reference, vorbis pre-rc4 with -q 5 (~160kbps) doesn't have this problem) |

[JAZ], I beg to differ. Vorbis pre RC4 CVS from July 4th, -q 5:
http://seed.d2g.com/awe32-20sec.ogg Very obvious artifacts at the beginning. I find that only Psytel's AAC encoder handles this sample at around 192 kbps. MPC and Ogg need higher bitrates to eliminate the artifacts. Cheers |
