Because: 1) Even with the shortest implemented decay time of 2s that feature results in noticable volume-pumping which I consider very annoying. If the chip has shorter decay times availiable it might be better, but I don't have a PDF reader here to check. 2) The chip can't see into the future, offline pre-processing like replaygain can. This can preserve intended differences in dynamics across a track that would be reduced or killed by the MAS-limiter. BTW, just for the record: I prefer not to modify my MP3s, my main index is based on an MD5 of the file. -ik Received on 2003-09-12 Page template was last modified "Tue Sep 7 00:00:02 2021" The Rockbox Crew -- Privacy Policy |
