At the moment, until I can either implement the Asio4All patch, or
address the problem at a hardware level, I'm stuck using what
InitializePsychSound says is a soundcard with high latency (running
under Win XP).
As I understand it from the PsychPortAudio('Start'...) help, this
means the 'when' parameter will be subject to latency and variability.
(Fixed latency I can live with, but I'm guessing the variability will
be bad.)
Setting the waitForStart parameter to 1 means that "the optional
return argument 'startTime' will contain an estimate of when the first
audio sample hit the speakers, i.e., the real start time". Can i
assume that this time stamp will be subject to inaccuracies on my poor
hardware too? I.e., this timestamp will not be an accurate estimate
of when that audio hits the speakers?
Thanks.
