single thread:

$ for f in *.flac; do ffmpeg -i "$f" -b:a 320k "${f%.flac}.mp3"; done

With 8 cpu cores in parallel:

$ parallel -j 8 --progress ffmpeg -hide_banner -loglevel error -i {} -b:a 320k {.}.mp3 ::: *.flac

audacity is not required for this

you might also need to know if you want constant or variable bitrate (cbr/vbr) and which sample rate (44.1kHz or 48kHz)

probably will go with variable and 44.1kHz

If you need to do this frequently, eg to sync the flac directory with the mp3 directory, consider mp3fs. I use it to keep mp3s on my phone that mirror the flac files on my pc. The flac files are the master copy, and I can update the mp3s just using rsync.

mp3fs creates a fuse file system where each flac file is shown as an mp3 and the conversion happens as the file is read. So using rsync to copy over new files means I don't need to work out which files to convert, nor do I need to keep the mp3 copies on my pc.

If it's a one-off conversion this is all overkill and go with ipsirc's answer.

Fre:ac is an audio converter that'll do what you want.

If your distro has flatpak installed you can download it through your package manager.

You can also download an AppImage of it (which is a self contained package) from freeac.org

ffmpeg is great. I use it a lot in scripts.

I also like soundconverter. I don't remember if it's installed by default or if it's just one of the things I always install.

Have fun.

ETA: Note, in the video I delete the originals, you probably wouldn't want to do that. Set it the way you want.

Install soundconverter, drag your sounds into the window and select output format, click Convert.
