App for downsizing MP3s automatically when copying to a phone? (sh.itjust.works)

I'm ditching streaming services and just going with local music. However all my CDs are converted to either flac or 320kbps mp3 files on my PC and thus far too large for the limited storage I have on my phone.

I was hoping there might be an app that would automatically downconvert to something like 128kbps and then copy over to the Music directory on my phone. A bit like how Calibre can automatically convert eBook files (e.g. mobi to epub) and then send them to your ereader?

Navidrome does that. You have to setup a PC, or a raspberry Pi with navidrome, and then use a client like Symfonium (costs $5, not open source, but it's the best subsonic client out there), and tell it to automatically downconvert music when played via the phone. I have a Raspberry Pi 3B+, with just 1 GB of RAM, running navidrome. DietPi + navidrome (which is installable directly via dietpi's software selection), together they take just 80-120 MB of RAM!

I had Jellyfin before that, and Emby, and they were dogs. 1 GB of RAM was not enough for them, they'd swap with an additional 200-300 MB of RAM. And they were slow with large music libraries too. Navidrome/Subsonic don't have such issues. Big music libraries are handled fast with their db/engine.

If you prefer to not use a server, there are encoding shell scripts that do batch-encoding: https://github.com/caleis/flac2mp3/blob/master/flac2mp3.sh

    Tempo is a good open-source player for Android that works well with Navidrome.

    On iOS, Arpeggi is good, but not open source (I think). It's still under development, but I don't think it's missing any major features at this point.

    Tempo is not maintained anymore.
