- Genera Brain
The Genera Brain is a DSP board I designed around the STM32H7 microcontroller. It is currently the foundational hardware platform for my own electronic musical instrument design. It is a small printed circuit board (2.1” X 3”) that includes a 32-bit ARM microcontroller, an external memory IC, an SD card slot, and an audio codec, laid out in a design to maximize signal-to-noise ratio of the audio circuitry. I began this project in 2017 using a combination of funding from a Princeton Council for Science and Technology grant and a David A. Gardner Magic Grant, and have since used this hardware brain in all of my electronic instruments as a way to create electronic musical instruments that are not merely controllers for computers, but rather have their own dedicated synthesis voices.
It is described in the paper about the LEAF audio library (then called OOPS), OOPS: An Audio Synthesis Library in C for Embedded (and Other) Applications
