Title: Re: Calculating latencies
Hi,
Just an update on my issue of calculated v measured latency for a M-Audio Firewire410. After the tipoff I used AUPulseDetector in AULab, which does a very slick job of measuring latency through the wire. It reports the same latency figures as my test app - AULab reports the Firewire410 latency as 1362 samples under the driver properties in preferences and AUPulseDetector reports an actual 1251 samples so it looks like my original test app isn't guilty of introducing any error. Incidentally, altering the buffer size made no difference to the difference between actual and calculated.
At least it gives me an idea what error margin I will have to deal with and possibly incorporating a user calibrate mode that performs the same test as the AUPulseDetector for my final app.
Thanks,
Rick.
