Lossless AAC

First time posting, long time reader.

Hello everyone, I was wondering if there was any way to encode a lossless AAC (MPEG-4 SLS), I've searched for encoders but no luck.

I need to achieve three things, 1) Highest quality possible (space not really an issue), 2) MP3/AAC-like compatibility (files will be played in hardware that handles AAC at most, such as car stereo/TV/receiver, etc.) and 3) one file per song (no AAC+FLAC).

Most of my files are AAC@512, virtually transparent, identical to source (at least to my ears), but at such high bitrates I would rather go lossless.

I have decent audio equipment (home, car, headphones) so that's why quality and compaatibility are equally important. If there is no practical way to encode to MPEG-4 SLS/HD-AAC, what would you recommend?

Thanks!

Are you certain your player will play AAC SLS, it is not a popular format? Apple Lossless is the defacto standard for m4a.

I understand there is some kind of backwards compatibility, but I'm not sure if current hardware (car radio) will play the lossless or the lossy layer (or neither). Basically I just need the AAC encoding for compatibility purposes.

Edit: Some of my devices don't work with Apple lossless.

Definitely not both, and probably neither.  AAC-SLS is a dead format, nothing will support it.

Then I guess I'll stick with AAC@512 until FLAC gets widely supported.

Thanks guys!
