I have a collection of music in flac format and now I want to store them on my phone. flac files get too much space and downloading all the playlist in mp3 takes as much time as finding decent and real high quality flacs (there is plenty of songs on internet which only look like 320kbps and are not really high quality). So I decided to convert my flac files into mp3 and I prefer minimum amount of quality loss; what is the best software for it?

  • Doesn’t matter if conversion take some time if the quality would be decent.

        It’s one of the pillars of anything A/V. Most if not all streaming provider uses it in their backend and frontend, and most conversion and playback tools (ie: HandBrake, VLC) depends on it.

        It’s a CLI tool, it’s a great generalist tool for converting video and audio but you have to script it if you want to do a recursive batch job.

        ffmpeg is written by Fabrice Bellard, who’s one of the most underrated programmers in the world (he also wrote QEMU). It’s probably the best tool out there, still actively maintained, and most commercial apps are probably using it under the hood for any kind of conversion.

    I use FRE:AC https://www.freac.org/downloads-mainmenu-33

    It can do bulk conversions with a recursive directory search and works in most OSes

    I had the exact same use case as you, 1TB of FLACs onto a 256gb phone. Because you prefer minimal quality loss, Opus is the format for you, not MP3. You can maintain transparency-level quality with 128kbps, Opus is roughly equivalent in quality to a mp3 twice its size. AAC and Vorbis are also preferable to MP3 in this aspect, but inferior to Opus. At this point, mp3s are only useful for devices that can’t decode any better codec.

    Then i do a search-replace for *.flac -> *.opus on the playlists. I use PowerAmp on android to play the tunes, can recommend.

      PowerAmp has a good UI but lacks some features and usage ease so I highly recommend Musicolet.

        I just tried it. I can’t bulk import external playlists, so I’m not using it. I keep my playlists in with the music directories so I have to scroll past 3,000 artists to get to any of them in musicolet.

    dont convert them to mp3, use either AAC or Opus, 192kbps is typically good enough for high quality, but a lot of people will just encode 128kbps

    I dunno, I normally use my bash script + ffmpeg to convert batch flacs to mp3s

    #!/bin/bash

cd "${1}"

for subdir in *; do
    cd "${subdir}"

    for input in *.flac; do
        echo ${input%.*}
        ffmpeg -i "${input}" -ab 320k  -map_metadata 0 -id3v2_version 3 "${input%.*}.mp3" && rm "${input}"
    done

    cd ..
done

    Then i’d just run my script.sh [directory that contains flac] you might want to remove && rm "${input}" if you don’t want it to delete your flac files automatically.

    I used to use musicbee for this. Good app for organising your music on your desktop and you can configure it to convert audio format when syncing to your phone. It’s been a while since I used it, but it did the job nicely

    If you’re using Windows then Foobar 2000 is great. I use it for manually managing and tidying my collection in addition to converting pretty much any format to any other format.

    That being said, you can install it as a snap in Linux as well if that’s your poison.
