The framework does not rely on any server side ressources and is capable to completely run locally in your browser. However you could publish the configured test scripts on a web server to easily reach your participants or even transmit the results to a web service for collection and further evaluation.
MushraJS has already been used for for real listening tests by the author and should work reliably. Anyway, please thoroughly test your setup before your public test starts.
As the framework uses modern HTML5 techniques for audio playback and the user interface it is very important to use a modern web browser. The support for different audio file types varies a lot between the different browsers. I would recommend to use .WAV files as these are lossless and supported by all major browsers with the only exception of the Microsoft Internet Explorer. Other file formats like .FLAC, .MP3 or .OGG are only supported by different subsets of browsers.
The configuration of the test is written in JSON format. See
Some of the texts, for example the introduction on the first page, can be edited in the
index.html file. The corresponding
<div> tags are marked by comments.
It is possible to send the results to a server script and to collect and evaluate them in a central place. See
results.php for a basic example. This saves the transmitted results in a human readable .TXT file with the timestamp in its name. This is not intendend to run out of the box and needs some PHP and JS skills to get it up and running. There are plans for a more comfortable server backend but currently no time is available to work on this.
