Thread: M4A codec dropping tags

  1. #1

    Unhappy M4A codec dropping tags

    Hello, I've recently had this issue come up on windows 10 21H1 (build 19043.1165) where on dbpoweramp 17.3 using any of the m4a encoders ends up with the final file dropping all artist, title, year tags but leaving replay gain and other tags alone. Ive not had this issue before until this week, tried clean installing and using the reset tool to clear out the registry settings with no luck. I tried a few different songs that I know worked before and still having the issue. If I use another codec such as opus it converts fine like before so not sure why m4a is having issues. Here's a picture of the tags being dropped between the flac source and m4a output.

    With FDK encoder:

    Re: M4A codec dropping tags

    One of the m4a files, right click on it >> Edit ID Tags

    The artist is missing there?

    Re: M4A codec dropping tags

    Yeah, it's straight up dropping artist and title tags on any of the m4a encoders, qaac or fdk. Here's a video of me taking a flac source with tags, and converting to m4a with no dsp or anything on a fresh install: https://puu.sh/I5b9u/260a2bfd60.mp4 I didn't see anything wrong in the logs and reinstalling didnt fix it so not sure what's going on. Never had this issue before so no sure if a windows update somehow borked it or something.

    Re: M4A codec dropping tags

    Uninstall dBpoweramp, full system restart (shut down), then reinstall dBpoweramp.

    Re: M4A codec dropping tags

    Hello, sorry for the delay, have been busy. I did the full uninstall, ran the reset program to clear out the registry keys, rebooted, installed the latest 17.4 build, rebooted again just to make sure, and tried converted a .flac to .m4a using qaac encoder. Same issue as before, Title, Artist, Album and year tags were dropped on the encoded file. I can send some more logs if you'd like to try to pinpoint the issue.

    Re: M4A codec dropping tags

    Please upload the converted m4a file to dropbox and the source flac file and personal message me a link.
