(no title)

I do something similar to OP but do the final transcoding to HE-AAC VBR 64kbps (ffmpeg params `-c:a aac_at -profile:a 4 -b:a 64k -aac_at_mode 2`). The tracks sound more than acceptable to me and this way I can easily store my entire collection (+80k tracks) into my iPhone. Modern codecs are wonderfully efficient.

Thanks for sharing your params... This is nice, maybe that's something I should consider. I need to test wether my car supports aac. My ipod does and kitchen radio is not that important.

You should See my audio books workflow with m4b-tool and audiobookshelf, which is probably even better ;)

Did you know ffmpeg has a non free Encoder (libfdk_AAC) thats sounds slightly better?

No problem, please do share any interesting part of your workflow if you have the time!

Ah yes. I'm not sure it sounds better than the audiotoolbox encoder though, at least it is reported that it doesn't here: https://trac.ffmpeg.org/wiki/Encode/AAC#aac_at although the hydrogenaudio source of this claim seems to be down, is still readable on the web archive at https://web.archive.org/web/20240407200855/https://wiki.hydr...
