I need to have a precise measurement of the delay in this loop :
- Generate Noise -> HP -> ASIO -> Mic -> FileWrite

With my configuration I obtain 70 ms of delay between the time I produced a sound and the time it is recorded to a file.
I am using a Creative X-Fi sound card with its ASIO driver and NuTech is configured to run at 48kHz with 4ms delay and 192 playbuffer size.

* Can the Leaff team tell me if this delay is know and clearly defined ?

* Can everyone using NuTech do the experimentation in order to know if this delay is dependant of the configuration / driver / hardware ...

Thank you in advance to everyone

it's dependent also on driver and hardware, but it should be predictable.

I made a NUTS that do need to be configured considering that delay.

If you know a way to estimate this delay automatically, I am definetely interrested.

Thank you for your awnser

You can use the CBFunction with the NUTS_GETLATENCY opcode to get the sound card input /ouput latency.

lParam: 0=to get INPUT latency 1=to get OUTPUT latency
wParam: (LPVOID) TriggerType (i.e. (LPVOID)AUDIOPROC to get sound card latency)

ReturnValue: the return value is the requested latency.

For Example:

AudioInputLatency=CBFunction(this,NUTS_GETLATENCY,0,(LPVOID)AUDIOPROC);
