    As stated earlier - LMS using transcoding means most (if not all current) audio formats are playable so whether a player can play a format natively is in practice irrelevant.

    So rather than a matrix of what is possible - I think the list of what is NOT possible would be relevant - I think that list is very small and mainly old formats. The only one I can think off at the moment is RealAudio. There are other old codecs or niche (e.g. MIDI) which are/were supported using transcoding by 3rd party plugins.

    MPEG-4 format (the usual container format with extension mp4) is a comprehensive standard aimed at handling multiple different sorts of media streams in the same file - so it can have video, audio tracks with chaptering, ads, metadata and subtitles - most of which is overkill for simple audio files with cover art and a bit of metadata and it does nothing to improve / degrade audio quality.

    FLAC 100% - If you subsequently want to convert from lossless to a lossy format you can easily do so but you can never convert from lossy to lossless without loss of quality. Also if you ever want to re-create a CD at its full quality you can easily do so from FLAC but not from a lossy format.

    To answer an earlier question - FLAC can store cover art in the file. Its not necessary for LMS if there is a single folder.jpg etc but it does work

    Note. LMS will read the cover art from the first track in the album if its is embedded in preference to folder.jpg / cover.jpg.

    Definitely true - but ALAC (Apple Lossless Audio Codec (ALAC)) is lossless - so no difference in that respect.

    I use MP3 and ALAC. I used to use flac, and it's great, and the crc bit flip checks is def in its favor, BUT I switched to ALAC bc ALAC is easier to handle both tagging wise, and natively with anything Apple. I rarely find anything that can't handle ALAC natively, but most Apple stuff won't do flac.
    Using: Win10 64 + LMS 8 & Duet & ipads w/the logitech app, and ipeng on an ipod
