The sample comes from a self-made song (with virtual instruments), where I use chorusing.
Originally posted by [JAZ] 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 128Note: 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)
Originally posted by rts I tested with lame --alt-preset standard, and I can hear a 'breating' sound around 8 seconds.Easy to year. Is this the artifact you mean? Can't hear it with --xtreme or --insane though.
Originally posted by [JAZ] This might seem a joke, but I've been able to abx 29 out of 33 (0.001) the freeformat 640 against the original. but probably 99.995% of people wouldn't get it.I can't really describe the difference, it was a sutble change in the chorus in one concrete part. Original seemed clean, while mp3 seemed not that clean.
