Tim’s website details building a synthesizer using C++ and WebAssembly.
Ever since I started taking piano lessons two years ago, I was curious to take a look into a vastly different field from cryptocurrencies and blockchain. That field being digital audio engineering. So when some of my freelance projects ended in November 2019, I decided to allocate my next three months towards building an audio product.
I quickly discovered what I wanted to build: A synthesizer. In C++! I had just watched some talks on WebAssembly, and was very curious to learn a new language too! In hindsight, the personal challenge, however, was to understand the data structures and math that go into generating audio.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
