hello, you could use the patch you've made last month for am-radio and use it to measure latency...

obviously the message is translated into voltage levels by a modulator and a demodulator. In the equation, you will need to substract the latency of the soundcard. hope you get what I mean, and find something in this way, best, patco.
hi patco
thank you for your thoughts. the problem is, that some time is needed to detect, whether the amplitude changes or not. that means to point of the change is not definable very precisely, which makes the measurements inaccurate. also i cannot send the sound produced by the [pd am-radio] to the speakers, because it uses a very high internal samplingrate (~1.5MHz or the like).
