cutting the attached file using
mp3splt -t 2.0
results in the last chunk end at 20 min even though the file is longer. same result with -t 5.0 and -t 1.0 and even -t 0.01, but interestingly not with -t 20.0.

what is going on? using frame mode fixes this, but is sooo slow.

    Hello,

    Thank you for reporting the issue.
    What version of mp3splt are you using ?
    It is possible that mp3splt fails to split correctly files that are VBR if you don't use the frame mode and they don't contain any Xing tag.

    However, the file that you are attaching doesn't look like a VBR file.
    What have you attached here ? The result of the last file when split using 20 minutes ? This file has 27.46 minutes and seem to split fine even without frame mode.

    Is it possible to give me the full input file ? You can send it for example by mail at m@ioalex.net if you don't want to post it here.

    please see example output. -t 5.0 gives 4 chunks instead of 6, the last one ending at 20 minutes. i dont know about xing tags and stuff, i hoped you could analyze the file.

    Hi,

    Sorry for the late reply, but you have to use the -f flag for frame mode to split such a file.
