But is it really so important? Do you watch the > timing information while listening to the song? to fix timing there is script Mp3Fixer for amarok Mp3Fixer (v0.9.4) About: Mp3Fixer is a script for repairing MP3 files which display a bogus track length or bitrate in your audio player. For example, if you have a track that you know is really five minutes long, but amaroK shows the length as one hour, then this script is for you. Mp3Fixer calculates the real track length and adds the missing XING header to the file. Additionally, Mp3Fixer is capable of repairing broken MPEG header frames. see also in portage: media-sound/mpck Checks MP3s for errors media-sound/vbrfixc Vbrfix fixes MP3s and re-constructs VBR headers -- Linux 2.6.17-gentoo-r7 AMD Athlon(tm) 64 Processor 3200+ 20:53:00 up 10:06, 6 users, load average: 1.23, 0.76, 0.45 -- gentoo-user@gentoo.org mailing list
