Audio Recording and Playback

[Eric T]

Hi,

We are developing an English language course, and want to implement the following functionality: allowing the learner to record himself and then be able to play back his recording.

I have seen this functionality in an existing course - UPValenciaX: BSP101x. However, I am unable to determine how it was created and how we can create it in our course.

I'm attaching an image of such an existing interaction:

Any assistance would be greatly appreciated.
