Dependencies and compatibility

Runs out of the box on any web server with PHP (tested on PHP 5.1<=), no third party software needed.

Alternatively, a local server (no web server or internet connection needed!) and optional Python analysis scripts run on Python 2.7 or 3.x. Plots rendered using matplotlib, NumPy and SciPy.

As Microsoft Internet Explorer does not support the Web Audio API, you will need another browser like Firefox, Chrome, Edge or Safari.
