As a counterpart to the recreation of analogue electronics using Web Audio, here’s a video demonstrating Acoustic Amplitude Modulation, or rather Electromagnetically Actuated Acoustic Amplitude Modulation Synthesis to be precise. That’s the title of a paper by Herbert Chang and Spencer Topel, both of Bregman Media Labs at Dartmouth College, in which they discuss a “new approach to acoustic amplitude modulation that builds on prior work with electromagnetic augmentation of acoustic instruments.” Details of the paper are summed up in this video.
