Subject: Re: [AUDITORY] Online rhythm production experiments: Update From: "Jacoby, Nori" <nori.jacoby@xxxxxxxx> Date: Tue, 26 Jan 2021 16:27:41 +0000--_000_3b7a72638f5048f188f853b70ff0a819aempgde_ Content-Type: text/plain; charset="windows-1250" Content-Transfer-Encoding: quoted-printable Dear auditory list, We would like to share this preprint to present and validate a recently dev= eloped technology in our group: REPP (Rhythm ExPeriment Platform). This tec= hnology is able to measure SMS in online experiments with high temporal fid= elity while also working efficiently using hardware and software available = to most participants online. We give details on the technology in the prep= rint as well as validate it in a series of calibration and behavioral exper= iments. We demonstrate that our technology achieves high temporal accuracy = (latency and jitter within 2 ms on average) and high test-retest reliabilit= y both in the laboratory and online. We plan to release this technology as= a free and open-source framework alongside the journal version of the pape= r. This technology is fully automated and customizable, enabling researchers t= o monitor online experiments in real time and to implement a wide variety o= f SMS paradigms. For example, using REPP we successfully replicated online = a transmission chain experiment to estimate perceptual priors for simple rh= ythms via iterated reproduction of random temporal sequences. In a recent p= aper, we also show that REPP can be used to collect a large tapping dataset= with more than 500 participants to study individual differences on SMS in = the general population (Niarchou et al., 2021). We therefore believe this t= echnology can support SMS experiments that would be nearly impossible in th= e lab while massively increasing the scalability and speed of data collecti= on. https://www.biorxiv.org/content/10.1101/2021.01.15.426897v2 Very best, Nori Jacoby, Manuel Anglada-Tort, Peter Harrison Nori Jacoby Max Planck Group Leader, =93Computational Auditory Perception=94 Max Planck Institute for Empirical Aesthetics Gr=FCneburgweg 14, 60322 Frankfurt am Main, Germany nori.jacoby@xxxxxxxx<mailto:nori.jacoby@xxxxxxxx> +49 69 8300479-820 ---------- Forwarded message --------- From: Prof. dr Henkjan Honing <honing@xxxxxxxx<mailto:honing@xxxxxxxx>> Date: Mon, Oct 26, 2020 at 5:24 AM Subject: [AUDITORY] Online rhythm production experiments: Update To: AUDITORY@xxxxxxxx<mailto:AUDITORY@xxxxxxxx> <AUDITORY@xxxxxxxx= ts.mcgill.ca<mailto:AUDITORY@xxxxxxxx>> Thanks for the suggestions. Below a brief summary of the responses I receiv= ed. These came in three flavors: 1) solutions suggesting specific hardware at the client side (e.g. using e.= g., a two channel audio card) 2) solutions using client side software (e.g., javascript) 3) offline and/or post-processing solutions For our purpose (relatively large-scale online rhythm production experiment= s) solution type 1 is unrealistic. [input from Werner Hemmert and others] Solution type 2 was tried by several researchers/institutes (using, e.g, Ps= ychoPY javascript, etc.). However, most report - as expected - relatively l= arge timing errors, largely due to keyboard scan rates, drivers, and/or ope= rating system (as reported in the references mentioned in the original mess= age). (Despite the claim of psychopy.org<http://psychopy.org> of <4ms preci= sion in online studies). [Input from Ignacio Spiousas, Nick Haywood, Ben Schultz, Kyle Jasmin and ot= hers] N.B. PeerJ recently published a comparative study [1] Solution type 3 was suggested by some: i.e. o record the rhythmic pattern b= y tapping e.g. with a pencil on your desk or device microphone, along with = the streamed sound, at the client side, upload the resulting audio file usi= ng a standard browser, and analyse it at the serverside using onset-detecti= on and some crosscorrelation techniques. Depending on the sampling rate, la= tencies can be reduced to 1 ms or less. [Input from Roger Dannenberg, Krzysztof Basi=F1ski, Justin London and other= s] N.B.1 Ben Schultz announced to make his version of Solution type 1 availabl= e as open source (repeated below). N.B.2. Nori Jacoby announced to make their version of Solution type 3 avail= able as appendix to a forthcoming paper (repreated below). Nevertheless, my hope is still on some elegant solution of type 2. If you h= ave one, please let us know. Best, Henkjan Honing [1] https://peerj.com/articles/9414/ .

We=92ve = 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 practic= al in terms of realistic online data collection. We plan to publish a prepr= int by the end of the year and therefore make the details of the technology= accessible to everyone soon.
