    Who says it's incorrect? Is it VBR? CBR? Would you have an example file?

    It's probably just more precise than you'd expect it to be. Bitrates
    aren't perfect, exact integers, but always an approximation to a desired
    target value. Some applications probably just round up/down to some
    group of well known bitrates.

    Incorrect bitrate display?

    Running LMS 8.1.1 on Ubuntu.

    I've noticed that track bitrate is sometimes displayed incorrectly. For example, for many of my 320 kbps MP3 files LMS displays them as 319 kbps. Not a big deal, but is this something that can be corrected?

    Thanks!

      Are you sure they are 320kbps CBR. I have a lot of VBR MP3s that display 317 or similar, but CBR files display 320.

        Yes, I suspected it may just be a rounding issue.

        It's a CBR file. Here is one example:


        LMS displays it as 319 kbps.

        Foobar2000 shows 320 kbps, and so does Windows 10.

        Here is what MediaInfo reports:
