It is described here: https://code.videolan.org/mansr/mqa/-/blob/master/mqa.rst
Thanks. I took a look over that. Based on that and @Cebolla's description of the Tidal streaming, it appears that:
1. Green light: presence of an encrypted stream. I presume detected from the magic value plus checksums? So if the magic value isn't there, then MQA isn't detected or decoded?
2. Blue light, encrypted stream as above with auth_level greater than or equal to 9.
Is that correct?
I notice your description of "The position of this bit within the 24-bit samples is in the range 8-15 inclusive". How does that square with the belief that MQA only impacts on the lower three bits of a 16 bit stream?
