Latency measurements

[pcournoyer]

I just got a MOTU 828mk3 and in the process of doing some tests / benchmarking I tried to use the CEntrance Latency Test Utility but somehow it does not work anymore with the MOTU control as the latter forces a reset on the ASIO driver and the two applications seem to fight for the driver endlessly.

After an empty search on the web for another such tool, I ended up doing it the hard way: use mda VST test tone impulse generator, route one output directly to a file recorder, route the second output across the audio interface --> loopback --> and back into the same file recorder. Load the recorded file into Cubase and measure the delay between the pulses.

Doing it one time is not too bad but repeatedly for different buffer sizes, analog / digital channels, etc... gets tedious quite quickly.

Anyhow, I was wondering if any of the BCA plugins were able to do latency measurements...seems like a good fit for your product line which is strong on the analysis type of tools.

Something as simple to use as a VST plugin with standard input / output audio pair and a simple readout in milliseconds is sufficient. Bonus feature would be to have more long term information such as pulse counter and min / max / avg latency readings over a session for example.

What do you guys think?

It sound indeed possible to do something. The only issue is that you will still have to plug the output of the soundcard into its input and thus check your soundcards settings to avoid an ugly feedback...

It could be an interesting tool but I am not sure it would be used so often. so the market for such a tool might be small and thus the price much higher than what you might be used to...
