# Limut



Live coding music and visuals in the browser. Inspired by FoxDot with a desire to make it more accessible by running in any modern browser with no installation. Approach to visuals inspired by Crash Server's `video` player, and shadertoy :-)



# Documentation



Documentation is available in the page itself, underneath the console.



# Try it



Try it at https://sdclibbery.github.io/limut/



Example limut code can be pasted into the editor to see what Limut can do; this can be found on the page under the editor and console windows, or there are many examples (including some technical tests) at https://github.com/sdclibbery/limut/blob/master/examples.txt



Please report problems / bugs / browser issues etc as github issues at https://github.com/sdclibbery/limut/issues



# Releases and breaking changes



Normal development should be backwards compatible. There is no specific log of added functionality (apart from the commit log).



Occasionally, breaking changes are introduced; when this happens, a new github release is produced: https://github.com/sdclibbery/limut/releases to document the upgrade path for user code.



# Electron app



Limut can be run as a website, or packaged into a desktop web app. With npm installed, run `npm install` to install electron, and then `npm start` to run the electron app. There are no prepackaged versions available at present (pull requests welcome).



# Code Editor



Limut uses the CodeMirror editor by default (https://codemirror.net). This provides syntax coloring. However, on some devices (eg mobile) a better experience may result from using a basic textarea editor; this can be enabled by using the `?textarea` url parameter.



# Development



Run locally by firing up `./server.sh` and connecting a browser to http://localhost:8000/?test . The unit tests run on page load when the `?test` url parameter is present; view output in the browser console.



# Samples



Piano sounds: https://archive.org/details/SalamanderGrandPianoV3



Limut's audio files have been copied from FoxDot (https://github.com/Qirky/FoxDot), where they were obtained from a number of sources. Here's a list of thanks for the unknowing creators of FoxDot's sample archive.



    Legowelt Sample Kits

    Game Boy Drum Kit

    A number of sounds courtesy of Mike Hodnick's live coded album, Expedition

    Many samples have been obtained from http://freesound.org and have been placed in the public domain via the Creative Commons 0 License: http://creativecommons.org/publicdomain/zero/1.0/ - thank you to the original creators

    Other samples have come from the Dirt Sample Engine which is part of the TidalCycles live coding language created by Yaxu - another huge amount of thanks.



If you feel I've used a sample where I shouldn't have, please get in touch!



# Waveforms



Some waveform tables are taken from the Web Audio Samples repo, under the Apache license: https://github.com/GoogleChromeLabs/web-audio-samples



# Shaders



Many shaders are based on ones from https://www.shadertoy.com/ , and the shadertoy synth uses the Shadertoy.com API to load shaders directly from shadertoy.
