besplit/wbias - cutting mp3s - problems with timestamps

14. i'm using WBIAS together with Winamp, trying to cut AC3, but having problems with the timestamps. the weird thing is that when using WBIAS&WinAmp for cutting MP3 everything works fine.
make sure that you're using using Valex AC3 winamp plugin.i have the same problem while cutting mp3s, wbias doesnt cut at the right spots.

i tried winamp 2.80 and 2.81; wbias0.81 with BeSplit v0.82 and BeSplit v0.9b4; mad plugin and nullsoft (regular) plugin, file with and without vbr header

the logfiles all look like that example:

hi bond,

177seconds=2mins & 57 seconds.
180seconds=3mins.

also, i've already told you that BeSplit cuts between mp3 frames, so it can't differ miliseconds. resolution is about 20-40msec.

hi

yeah i already know that but the difference between the cut and the "should be" is ~1 or 2 seconds

[DSPguru]

1. please post a BeSplit v0.9 logfile.
2. please replace "177,822 180,009" with "177.822 180.009".

great ! so "177.822 180.009" did the trick.

no i am sorry but this didnt really help. lets say with "," the difference was 2 seconds and with "." 1 second.

i think the problem are the timestamps shown up in winamp?
