Hi
Robert In SenseLab we have extensive experience from developing a professional tool specifically for web-based audio testing (our commercial product SenseLabOnline). In a recent paper by our programmer – presented at the Web Audio Conference 2017 - he highlighted several challenges with web-based audio testing – concerning the issues/bugs in the
various browsers. Excerpts from the abstract: In listening tests, detailed sound control is sometimes mandatory down to each individual digital sample value and guarantee is needed that they are not unintentionally altered.
… This paper analyzes such compromises by discussing technological limitations of Web Audio API followed by validation measurements of sound playback in popular internet browsers. The measurements show that at the detailed
level there are significant differences in actual performance of different browsers and behavior is not always as expected.
Finally, a solution is presented where audio presentation is delegated to an external audio presenter for situations where the limitations of Web Audio API are not acceptable. Full paper here:
Hi-precision audio in listening tests - also in the browser? http://eecs.qmul.ac.uk/~keno/28.pdf The conference may include other papers of interest for you! Yours sincerely Christer P. Volk

On Behalf Of Valeriy Shafiro Here's one more potential "low tech" solution for web based audio testing. We are starting to use ISpring software, which can be integrated and accessed through Powerpoint. It is more intuitive and accessible for those who have limited
programming skills, though there are, of course, some quirks to get around. The software was developed for online education but has audio capabilities and testing options that make it suitable for many audio tests as well. I don't recommend it for psychoacoustic
experiments where precision and timing is key, but for many suprathreshold perceptual listening tasks with speech, music and environmental sounds it seems suitable, at least on the first pass. But as I said, we are just starting to use it, so I don't have
reliable data yet on lab vs. web comparisons. Valeriy On Fri, Nov 9, 2012 at 1:34 PM, Robert Zatorre <robert.zatorre@xxxxxxxxx> wrote:
