Koelsynth – a simple FM synthesis library
This is part of my journey on pybind11. I wrote a tiny FM Synthesis library in C++ and a Python wrapper for that using pybind11. There is a command-line piano app in the examples directory if you want to play with it. Here is the link: https://github.com/charstorm/koelsynth/tree/main/examples/si... My next target is to attach this to some kind of physics simulation - like a bunch of balls moving around in a box with some internal walls. When the ball hits certain trigger points, it produces the sound.
In plain words
Koelsynth is a lightweight FM synthesis library written in C++ with a Python wrapper built using pybind11. It includes a command-line piano application for experimentation. The library enables sound generation through frequency modulation synthesis and is designed for integration with physics simulations, allowing audio to be triggered by collisions or events within virtual environments.
