AFAIK, there is no simple, standard ‘Sonic Pi’ way to access (other than directly playing back) the data of an audio stream or sample. It would likely require dipping into some custom Ruby code to do so, or communicating with an external program to do it.

Also, similar ideas to this are indeed on our wishlist :slightly_smiling_face:
