Check out this animation of optimization for a near-uniform distribution of nodes on the surface of a sphere. Nodes are modeled as charged particles constrained to the surface of a sphere that mutually repel one another. Each frame is an iteration of the optimization process that minimizes the total potential energy in the system. Iterations are stopped after convergence or 200 iterations.
I just returned from visiting the 2017 WASPAA workshop and 143rd AES Convention in New York. Two very different vibes: the former is a small workshop focused deeply on the theory on topics including source localization, source separation, acoustic scene analysis, spatial audio, dereverberation and de-noising. AES is a huge gathering of audio professionals from music producers to mixers to hardware manufacturers to researchers like me. I’m back at the office with renewed enthusiasm for my profession!
Thank you to everyone who helped organize the 2017 Joint Workshop on Hands-free Speech Communication and Microphone Arrays. I was proud to play my part both as a first-time conference organizer and as a participant. Looking forward to HSCMA 2020!
