Hello guys, the question is simple
can I obtain low latency USB audio behaviour when using Mod Duo/Mod-DuoX/Mod-Dwarf with Windows 10?
The Mod uses Linux’s UAC2 usb audio gadget module. When connected to Windows 10, built-in drivers
are used to recognize USB audio device. These drivers are documented here:
These are NOT ASIO drivers. AFAIK ASIO drivers for UAC2 usb audio gadget module doesn’t exist or
are not open source.
But it seems that Microsoft has introduced some low-latency behaviour to their drivers
in particular they state that
Without any driver changes, applications in Windows 10 will experience 4.5-16ms lower latency. In addition, if the driver has been updated to take advantage of the new low latency DDIs that use small buffers to process audio data, then the latency will be reduced even more. If a driver supports 3ms audio buffers, then the roundtrip latency is ~10ms.
Well who knows if their UAC2 driver is using DDIs or not. They made the driver
Other related scenarios could be usage of asio4all over UAC2 drivers…any thoughts?
