Audio Recording API

One point I’ve been curious about is just how much data the USB Audio can ‘shovel’ reliably. Here on my ARMX6 Stereo 192k/4 byte per sample transfers work symultaenously for capture and playout via the 2i2 3rd Gen. I’d suspect combining in and out streams may be more prone to clashes than just capture or just playout. But it seems to imply that 4 channel one way at 192k/4byte should work, and thus also 8 channel 96k/4byte one way. However Sod’s Law tells us there is a snag which I’m clueless about! And my results are using an ARMX6. So some other machines may not be as fast, etc.

FWIW The Linux people have dealt with the Focusrite series OK and now can use the multichannel examples and have cracked the host software control. So at some future point it could be possible to lift some of their discoveries.

I have asked Focusrite about such matters, but they seem to feel it a secret and only care about Doze and Macs. So won’t even explain why items like the 2i2 work “out of the box” with RO despite them claiming they won’t unless you install their software. Having made stuff for people to buy this baffles me. Why deter people from buying what you make when it will actually work nicely? Bonkers.

Above said, if it will help I’m happy to get a 6i6 or similar and try it sometime.
