Web Audio Weekly


I'm going to make a renewed effort to get this newsletter out on a regular schedule in 2022, but will aim for monthly rather than weekly. If you're celebrating Christmas this week, I wish you a merry one, but whatever you're doing I hope you're safe and find some time to rest and relax. Your kind emails, links and support have made 2021 a little brighter for me, thank you!

A series of generative artworks from Tero Parviainen. I don't fully understand the market place aspect of this, but the resulting sounds are great. Tero shares some more detail in a twitter thread.

The DX7 synthesizer's exponential circuit, reverse-engineered


I created the high-resolution die photo below by compositing over a hundred microscope photos. Around the edges, you can see the 64 bond wires attached to pads; these connect the silicon die to the chip's 64 pins... I discussed the chip as a whole in my previous DX7 article; now I will focus on the exponential circuit.
