The answer for what is 'Hi-Res' would be varied depending on who you ask. I consider lossless 96kHz 24bit audio Hi-Res and Mobius supports that in 2ch USB mode without head-tracking. LDAC is not lossless so it does not fit the definition. I have seen 48kHz 24bit or 16bit audio also called Hi-Res. It is important that the full chain including DSP is capable of handling the same sample rate and often times 96kHz would push the limits on what an board DSP can do and having to keep an eye on power usage too.
I consider being lossless, avoiding sample rate conversion and keep distortion low more important than having a label that claims a higher sample-rate. The chipset used in Penrose is capable of handling 96kHz 24 bit Audio without having to resample to a lower rate, but there were are couple of factors we had to consider.
- Consoles support 48kHz audio only and you do not have much control over that.
- Sending 96kHz 24bit lossless audio using wireless technology is a steep ask and not many field tested solutions exist and given (1) above there it was not enough of a motivating factor for the use case of Penrose.
I think that makes complete sense. Low latency and lossless audio are much more important than hi-res support. There's no doubt that the wireless solution in Penrose is technically superior to LDAC just by the fact that LDAC is lossy. On top of being lossy, LDAC doesn't actually delivery 24/96 audio, even at it's highest bitrate (which is unstable and unachievable by many sending devices). I'm doubtful that hi-res would benefit the Penrose at all anyway.
