    The new Media Assistant app does mp3 (batch) conversion, and lots more.

    @tja It's been a while but I guess that you'll still find some information on the hydrogenaud.io forums.
    An older detailed result report can be found here:
    http://listening-test.coresv.net/results.htm

    Edit: A more recent blind test, comparing different AAC encoders:
    https://hydrogenaud.io/index.php?topic=120062.0

    Thanks, but those are what I posted above - they are not tests of AAC at any rate against a max. MP3 (defined as VBC and -V0 with lame, but maybe the FFMPEG is even better?)

    I don't expect MP3 to beat AAC at rates of 128kb/s or lower!
    But I suspect that a max. MP3 may be the same experienced quality as any AAC.
    At least for most ears.

    I am tempted to run my own test - here on the forum.

    Which AAC encoder is rated best?
    Maybe on all of iOS / iPadOS, Windows, Linux and macOS?
    Just in case you know ...

    I think that Apple's encoder is still amongst the best rated ones.
    I'm only using it on the Mac commandline but I'd expect the Windows version coming with iTunes to be the same.

    @tja This is my command line for encoding at 160k:

    afconvert "inputfile" -o "outputfile.m4a" -q 127 -b 160000 -s 2 -f m4af -d aac/

    afconvert sits in /usr/bin/.

    @tja 160k was the best from my own listening tests, I couldn't spot a difference at this rate and since the encoded files are for my own use, that's OK.
    m4af is the file type. I had issues with compressed files that just didn't work in some apps and "m4af" fixed it for me.

    how did the file sizes compare?

    They only depend on the chosen bit rate. The encoders generally match that setting very well.
    If you're using VBR (variable bit rate), it will depend on the quality setting and the audio you're compressing.
    At bit rates between 96k and 160k, AAC/m4a and Opus sounded best to me and I chose m4a because of the compatibility in most apps.
