I'm Rob. I have a background was in electronic music production, music mastering, location sound for (very amateur) film, field recording and sound design, etc.

I had a very unrelated career and transitioned into tech a number of years ago. In 2021 I started getting into audio coding with ChucK. I found the edges of it pretty quickly and moved over to C++ for my audio ambitions. I made a detour into Rust but didn't stick around.

I am currently working on my own audio engine. The primary goal is to create music and sonic art with it. A secondary goal is to open source the project and start blogging about it. If anything listed below is interesting to you and you would like to read about it in a blog, please let me know!

Details about the engine:

• the core is a directed signal graph
  • allows feedback loops without breaking acyclicity
  • type level IO matching: intellisense/compiler enforcement for connecting nodes
  • IO types can be anything, doesn't have to be audio
• compiles as a static library with CMake
• test suite with GTest
• Audio output with PortAudio
• .wav output with Libwave
• MIDI input with RtMidi (kind of buggy)

So far I have used to the engine to build a few GUI-less tools:

• wavetable oscillator with stereo detune
• NxOsc - N oscillator subtractive synth
• data and target agnostic step sequencer
• Filters and EQs
• Various envelopes: ADSR, automation clip

I am re-inventing the wheel with a lot of this, but it's helped me understand how to invent wheels which is pretty cool.
