Re: [AUDITORY] Online rhythm production experiments

[Samuel Mehr <sam@xxxxxxxxxxxxxxx>]

Hi Henkjan & list, we haven't heard of a solution for this, but have tried a few times to do synchronization experiments to little avail. My sense is that there is quite a bit of variability in latency across physical keyboards, browsers, internet connections, operating systems, etc etc, such that it makes what seems like a simple problem rather hard. I'd love to hear if anyone has a solution.

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.
