HF R800 Mic Audio Digital Depth

[JohnGriffith]

When I use an external microphone with my R800, what is the depth of the digitized audio?  16-bit?  24-bit?

What processing is applied to the analog audio?  Any compression?

Page 268 of the manual only shows "MPEG-2 AAC-LC (2ch)" for audio.  No other specifications.  I would find it extremely unlikely it would be 24-bit.  That's typically only found on professional equipment.  Thus, I'd assume this is at most 16-bit.

Thanks, rs-eos. I suspected it's 16-bit. I was hoping for some definitive engineering information from Canon.
