Any sound can be expressed as a function from time to [-1, 1].

Sinusoid is an expressive framework to write these functions.

• index.ls: The entry point for the web app.
• worker.ls: The entry point for the worker, which executes user code in the background.
• src/engine.ls: Interfaces with Web Audio API and worker
• src/signals.ls: Raw waveforms and basic operations such as adding, cropping, delaying
• src/instruments.ls: Some basic fully-synthesized instruments
• src/util.ls: Mainly data structures for performance
• src/music.ls: Higher-level abstractions from music theory
• src/fft.js: Fast fourier transform, basically copied from Nayuki
• src/dsp.ls: Convolution, digital filters
• src/gui_components/*: React components

Currying with --> in LiveScript is slow. Therefore, functions like gain_db must be called like gain_db(-10)(orig_signal). Better yet, use the pipe operator: orig_signal |> gain_db -10.
