Hi Henkjan and everybody,
My research group has developed a technology that has solved this problem and allowed us to collect reliable tapping data in an online setup. We’ve successfully collected large tapping datasets this way, and we believe that our method fully addresses the issues mentioned in this thread (low latency and jitter) while also being practical in terms of realistic online data collection. We plan to publish a preprint by the end of the year and therefore make the details of the technology accessible to everyone soon. If you are interested in using the technology earlier, please contact me. Very best, Nori Jacoby Nori Jacoby Max Planck Group Leader, “Computational Auditory Perception” Max Planck Institute for Empirical Aesthetics Grüneburgweg 14, 60322 Frankfurt am Main, Germany nori.jacoby@xxxxxxxxx +49 69 8300479-820 From: AUDITORY - Research in Auditory Perception <AUDITORY@xxxxxxxxxxxxxxx> on behalf of Prof. dr Henkjan Honing <honing@xxxxxx>

We are looking for some advice from those that have been doing online rhythm production experiments in the last few years.
Rhythm production experiments that are performed online – like typing on the spacebar 'in sync’ to a fragment of streamed music – is notoriously tricky due to all kinds of delays mostly due to the effects of scan rate, device drivers and OS scheduling at the
client-side [1,2]; Delays / jitter in the order of 50-100 ms are not uncommon.
There are all kinds of workarounds available, like offline analysis of audio files or using estimation algorithms [3], but it might well be that some of you have solved some of these issues in a more direct way. For instance, a piece of software at the client-side
that handles the timing of both the streaming and recording the taps.
If you have experience on these issues, we would appreciate if you would email us your tips, solutions, etc.
