    I uploaded it to http://zimage.com/~ant/temp/MP3toWAVsample.7z (38.3
    MB). Please try extracting with mac OS Big Sur v11.4's Archive Utility
    app and playing its WAV file.

    On both of these systems:
    * macOS 10.15.7 (Catalina)
    * macOS 11.2.3 (Big Sur)

    Archive Utility: archive gets extracted but is not a proper WAV file and
    cannot be played.

    The Unarchiver: archive gets correctly extracted and can be played.

    I just right click on the file in Windows Explorer and its defaults with
    the 64-bit 7-Zip program from https://www.7-zip.org. I tried add to
    archive manually with its options (https://justpaste.it/img/69bd8aa11a51f92afa0b0d57ded0a00d.gif). Both
    were in my over decade old, updated 64-bit W7 HPE SP1 PC.

    Ok, thanks.

    Thank you for reproducing it on your end. :) Wow, even Catalina. BTW,
    how come you're not on v11.4 for Big Sur?

    Inertia, mostly. : ) I have several Macs of various models here at home,
    and while some run Big Sir, others run Catalina, mostly because I
    haven't yet taken the time to verify that all of the stuff I have
    installed is fully compatible with Big Sur. As an example, one of the
    headless Mac minis in my server closet is still running Catalina because
    it runs several critical Docker containers that must continue running
    24/7 without issue, and I haven't had time to test them in Big Sur. I'll
    get around to it eventually - no rush.
