Reply to comment by klogg4 in Which lossy codec to use compress with before Android BT AAC transcoding? by silver-shot

Hmm.. did not know that, I might do that - thanks!

You can also have some great experience with Musepack (sounds amazing, no generation loss because it's subband), but the problem is general compatibility - I refused it because I couldn't transfer it to my smart watch and to friends through messengers. Shame, because it's my favourite free open source format, I like it even more than Opus for my tasks.

To my experience AAC FDK VBR 5 is good. Bitrate is something like 200-210 kbps. Sound is generally transparent to me.

Yeah, considering it's my first time hearing musepack existing.. I can imagine it might not be as widely supported.. :/

Imagine it being older than Vorbis and Opus. Early 2000s.

Maybe the lack of documentation killed it, but in fact it's one of the most epic lossy codecs I have seen.

Nine different codecs 100-pass recompression test

AAC wins over 100 decode-reencode cycles. But as /u/klogg4 says it's not likely to matter with a single re-encode. I use the same earbuds as you and I don't really worry about this, I mostly use Spotify and Tidal.

AAC is decoded and re-encoded for BT transmission, it's not passed directly to the earbud. But it's also particularly resistant to generational loss.

Wow what a great read! I'll go for AAC then I think! :) Cheers.
