LDAC encoder?

Is there any publicly available LDAC encoder? I would like to do some ABX testing of this codec, at its 3 different quality levels, out of curiosity.

LDAC encoding is free, and has been ripped straight out of Android:

Decoding is not, and requires a paid per-device license. Good luck finding a decoder to perform your tests with.

Hmm looks rather complicated for me, I'll just settle for some basic subjective listening when I get my Qudelix 5K.

While we're on the topic of Android BT audio, do you happen to know if AAC files can avoid transcoding and be transmitted as-is these days? I did some googling and all I really found is one or two hydrogenaudio threads from a couple years ago, with inconclusive information. I guess it's probably one of those "black box" questions that nobody (other than google/apple/etc engineers) would really know the answer to.

No. Almost every Bluetooth pipeline will be taking the mixed PCM stream of the host machine and transcoding it to whatever format is chosen for the device.
