We could use offload, on roadmap for Hires audio on android PCM, maybe float instead of 24 bit. Need for 192kHz, Probably not use effects.
Does android support HBR audio now? As i know from Dolby guys, no customers in Android area are buying Dolby TrueHD license, so i guess the answer is NO. Most of the customers are from AV receivers and BlueRay players.
Afaik, no one is using high Bit rate audio atm, but there is increasing interest amongst Android OEMs.
There's a few things shipped doing 192kHz/24 bit - the LG G2 was one of the first IIRC.
Most of the x86 and ARM HW will support HBR audio over ASoC PCM DAIs and HDA, but I'm not sure about which HDMI audio devices support HBR in HW atm...
It should be relatively common I suppose given that video sources have tended to use HBR for a long time (even DVDs do it as standard), though it's possible the mobile chipsets are limited in some way.
