Hello folks,
Is there a site/repository somewhere with numbers on audio interface latency?
I'm much interested in doing multichannel live audio processing and
the device latency matters a lot in this case. I'm especially curious
how recent USB audio interfaces provide in this regard. Anyone has any
numbers?
Lastly, here are some numbers for the firewire interfaces Edirol FA-66
and Presonus FIRESTUDIO Project I measured with jack_delay.
FA-66
