I analyzed some songs buy when i exported the pls i checked that the bpm field (with mp3tag) hasn't been updated with the new bpm number. Beatunes has it's new bpm number but exporting pls has the old one.

Thanks a lot

    Hey Stelios,

    What kind of beaTunes library are you using? iTunes-based or folder-based? (explanation)

    Did you see any error messages during/after the analysis (in the analysis panel)?

    Hi hendrik,

    i am using the latest version of beatunes (5.0.5), no i am not using itunes
    now (i had an itunes version installed but i didn't use it so after the
    problem with analysis results i uninstalled it and re-analysed the tracks
    with the same results) but it's folder based. My OS is win10 pro and my
    music library is a Traktor (2.11) library. I had also checked the results
    and noticed that the bpm field wasn't updated in Traktor too.

    Please open the beaTunes general preferences and check the box "Force overwriting of fields".
    Then please analyze the BPM for a couple of files again. Make sure to switch to the analysis view (does not happen automatically, when analyzing just a couple of files).

    1. Does beaTunes show any messages in the analysis panel?
    2. Does the BPM tags change now?

    If this does not help, please upload your logs (via beaTunes' Help menu).

    Thanks.

    beaTunes reads and writes both fields.

    The BPM field does not support fractions, which is why beaTunes also writes the FBPM field.

    When reading, beaTunes first reads the FBPM field. If it exists, it's returned. If it does not exist, the regular BPM field is used.

    If a rounded FBPM value is not the same as the BPM value, some other software manipulated one of the two values. Is perhaps Traktor re-analyzing the file when you scan it?

    I'd recommend to check with mp3tag before checking with Traktor.

    Deleted info from BPM field with Mp3Tag and scanned again some tracks with
    BeaTunes and this solved my problem. The problem seems to be ok with
    Traktor too. Anyway i will do more tests and let you know.
    Thanks a lot for your quick response and your precious time.

    Unfortunately Beatunes doesn't write in bpm field the demical numbers. In example the 124.563 is shown 124.000 in Traktor. Is there something that i am doing wrong or is there any proper way to do this?

    Thanks in advance

    That is not true.

    E.g. in MP3 files, beaTunes writes the non-decimal BPM value into the ID3 TBPM field, as required by the ID3 specification and additionally writes the fBPM value into a TXXX field, as many other programs do. The latter is a decimal BPM value.

    In example the 124.563 is shown 124.000 in Traktor.

    I have no idea how Traktor deals with this.

    Is there something that i am doing wrong or is there any proper way to do this?

    You haven't described what exactly you are doing.

    If you have a track with no prior BPM information and let beaTunes analyze it, it will write both the TBPM and the TXXX-fBPM fields.

    You are really fast!!!

    i did what i had described to previous (above) posts. Also i removed all bpm fields (bpm, fbpm, fbpm2) with mp3tag. I re-analysed this track with beatunes and check them with traktor and i had the same results.

    Stelios, please do me the favor of spelling out again, what exactly you did. That makes it a lot easier for me and leaves less room for misunderstandings.

    Also i removed all bpm fields (bpm, fbpm, fbpm2) with mp3tag.

    It's possible that beaTunes didn't notices that you did that. After all, it cannot re-scan all your files all the time to detect third party manipulations. To remove BPM info from files and then expect beaTunes to "know" about this, you must set the BPM value to 0 in beaTunes. Only then a re-analysis with beaTunes makes sense.
