Lambda Musika — The functional DAW

https://alvaro-cuesta.github.io/lambda-musika/

A JavaScript DAW that emphasizes functions as its core building block. In practice, a realtime audio scripting language and batteries-included DSP library, running on the web.

Keep in mind JavaScript is not the best language for CPU-intensive tasks, so performance will be limited.

On the other hand, it runs in your browser.

Usage

A Musika script is just a regular JS script:

• interpreted client side
• that returns a function t => [l, r]
• where t is time
• and l and r are output samples for the left and right channels in [-1, 1] range

For now there is no static documentation available, just dive in the source code and learn form the default song and other examples.

- Available defines:

• sampleRate, current audio device sample rate.
• setLength(secs), sets the total length of the song in seconds.
  • Used to seek using the time slider.
  • When omitted the time slider is disabled and the sound is played endlessly (useful for drone or procedural music).
• Musika, the Musika library:
  • Generator units
  • Envelope functions
  • Filter units
  • Operator functions
  • Music helpers that aid with traditional composition.
  • Util

- Script skeleton:

const {Generator, Envelope, Filter, Operator, Music, Util} = Musika

return t => [0, 0]

Development

• Start a development server at localhost:8888:

npm run dev

• Build the application in the build/ directory:

npm run build

• See open tasks
