RubySynth is a collection of DSP code snippets, held together with duct tape (as one does), to generate (electronic) music with pure Ruby.

I’ve built this for my Talk at Euruko 2019 in Rotterdam called “The musical Ruby”. This website primarily acts as additional reading material for people who have seen the talk, either online or at the conference. You probably want to start here

You can find all source code, including the code for this website at halfbyte/rubysynth on GitHub.


Thank you to Sam Aaron for SonicPi

Thank you to Lance Norskog for creating SoX and Chris Bagwell for maintaining it for more that 20 years now.

Thank you to the amazing MusicDSP mailing list of where most of the more complicated DSP code has found it’s way into this project.
