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.
Another vote for ffmpeg. I wrote a bash script that is basically just a wrapper around a for loop that uses ffmpeg. It asks your input and output type, converts all specified files in the directory, and asks if you want to delete the input files, now I just use that. It ain’t much but it’s honest work (and the good parts were taken from stackoverflow.)
