It appears not as a simple random jitter, it is more systematic. Then, it jumps back to the high latency value repeating the process.Īfter decreasing its latency with every loop (it needs 6 steps), that is where it ends before jumping to the high latency again: The latency starts high and is reduced with every loop. Interestingly there appears to be a wandering of the signal. Unfortunately, I did not manage (unitl now) to work in WASAPI exclusive mode. I reached the best timing using the ASIO drivers. Since they are able to present a jitter-free acoustic stimulus I know it is possible.

Playing around with different settings regarding driver and API, I ended up with various latencies but I was never as good as Psychtoolbox or Presentation. Default sampling rate for this is 44100Hz. In PsychoPy, I generate an 'A' with the inbuilt function sound.Sound('A'). Its highest possible sampling rate is 192kHz. But the field is grey, so I don't know whether this has any meaning. For the Steinberg system the value cannot be changes but it preset to 44100Hz.
Changing that to 44100Hz did not change anything.

In the Windows sound setting, system's default for the inbuilt speakers was 48000Hz. Sounddevice.PortAudioError: Error opening OutputStream: Invalid device ĭo you have an idea on what is going wrong?
