A compositional library for musical composition.
If you want to see pointillism in action and what it's capable of, run the examples in the
examples folder.
Note: Some examples may be loud, dissonant, and/or jarring. Hearing discretion is advised.
The way in which pointillism outputs audio is by writing sample by sample into a 32-bit floating
point .wav file. Internal calculations use 64-bit floating points.
For convenience, the Signal trait is provided. Types implementing this trait generate sample data
frame by frame. If the type also implements SignalMut, it can be advanced or retriggered.
Signals may be composed to create more complex signals, using for instance the MapSgn and MutSgn
structs. Moreover, you can implement the Signal and SignalMut traits for your own structs,
giving you vast control over the samples you're producing.
Signals that generate audio on their own are called generators. Their names are suffixed by Gen.
Signals that modify the output from another signal are called effects.
You can think of pointillism as a compile-time modular synthesizer, where every new struct is its own module.
Advantages of this design are extensibility and generality. It's relatively easy to create a highly customizable and complex signal with many layers by composing some functions together.
The downside is that these synths end up having unwieldy type signatures. Moreso, it's really hard to build synths in real time.
The following versions of pointillism exist:
