This perceptual study is used in our SIGGRAPH Asia paper Crumpling Sound Synthesis [Cirio et al. 2016]. The codebase is forked from Alec Jacobson's github codebase. We made a few changes so that it better supports the audio file play and stop features.
For a live demo, try this. To complete the whole study, one might take upto 30 minutes.
The following is from the orignal description.

This is nothing more than the .php/.javascript/.css/.html files we used to create the two-/four-alternative forced choice perceptual study for our Transactions on Graphics paper Ink-and-Ray: Bas-Relief Meshes for Adding Global Illumination Effects to Hand-Drawn Characters, [Sýkora et al. 2014].
I've left it in tact as a working demo, and hopeful it's obvious what to edit to customize.
It is based heavily off of code from Yotam Gingold.
To get an idea of the client-side interaction, try the live version.
On the server-side, upon completion of the survey simple plain text files of the responses in json format are generated and saved into:
/data/[experiment name]/[unique id].txtThen you can suck out the individual data entries in batch using your favorite command line tools/scripting languages.
If your institution/government requires it, you might consider placing your IRB approval information on the first page of the survey.
