Processing Audio html-audio-response

[ghost]

Does any one know of any demos that show how to save audio? I am trying to build an audio-rt experiment and have been told I need to use this plugin but I am not sure how as the only example I have found is that of @meilinz https://github.com/meilinz/picture-naming/blob/master/examples/jspsych-image-audio-response_chinese.html
I am unsure whether this saves 1 audio string and how I would process this to get reaction times, apart from manually
