I currently rip my physical CDs to FLAC and then convert to mp3 for playing in various players: car, phone, desktop/laptop. Having the FLAC is proof against physical loss, at the expense of maintaining backups. Having MP3 is for convenience and storage size.
I do the same conversion-to-mp3 process for other downloaded/streamed container sources besides FLAC, such as WAV, MP4, WEBM, MKV, M4A, etc. (where I want to extract only the audio component).
My question is, what are good ffmpeg parameters for a non-audiophile setup, such as car? Currently, I'm using ffmpeg -i FILE.flac -c:a libmp3lame -b:a 128k FILE.mp3 but I may be way off in my understanding of ffmpeg. For sources with video such as mp4, I'm using plain old ffmpeg -i FILE.mp4 -vn FILE.mp3. I'm currently using ffmpeg 4.2.7.
For bonus points, what, if any, would be a good set of parameters for an "audiophile setup"?
