I’ve been using JDownloads2 to download from YouTube Music. But my car stereo only supports mp3 so have to convert the files. Any suggestion for good audio converter that works in large batches? I’ve looked, and maybe my google fu sucks, but can’t see a way to force JDownloads to do MP3, it’s doing m4a.
Just remember that whenever you convert, you are losing fidelity. The only exception is when you convert between lossless formats.
I suggest you get as much music as possible in FLAC, then make mp3 copies you use only for devices that require it. Upgrade equipment when finances allow.
For everything else, also keep your original, like m4a, to keep sound quality at the best you can.
