I Dropped My Phone The Screen Cracked

I Dropped My Phone The Screen Cracked is a web audio library that uses method chaining and CSS-style selectors to simplify creating, configuring and connecting audio nodes in the browser. Here's hello world:

//create and connect sine and system out. start the sine __().sine().dac().play();

and a slightly more complex example:

//create and connect a sine oscillator (frequency of 180), lowpass, //compressor and system output (level of .5). __().sine(180).lowpass({frequency:160,q:5,id:"lp1"}).compressor().dac(.5); //select the sine using its type and change the detune to 10 __("sine").detune(10); //use the id to get a reference to the lowpass //filter and set the frequency to 600 __("#lp1").frequency(600); //create and connect a sawtooth oscillator, waveshaper & compressor //and connect the compressor to the existing dac we created above. __().saw(800).waveshaper().compressor().connect("dac"); //change the ratio of both compressors to 12 __("compressor").attr("ratio",12); //start the sine and the sawtooth __("sine,saw").start();

Audio node chains can be encapsulated as units using macros

//define a simple macro named "microsynth" __().begin("microsynth").sine().gain().end("microsynth").dac(); //change the frequency of the sine __("microsynth").frequency(100); //start it up __("microsynth").start();

and macros can be wrapped in simple factory functions to create plugins, making it possible to instantiate instances, connect them to other nodes, address them individually or as a group, nest them within other macros, etc.

//define a plugin called microsynth cracked.microsynth = function(params) { //pass any params to begin() so they can associated with the instance __().begin("microsynth",params).sine().gain(0).end("microsynth"); //return cracked so we can chain methods return cracked; } //create two instances with different ids __().microsynth({id:"micro1"}).lowpass().dac(); __().microsynth({id:"micro2"}).lowpass().connect("dac"); //change the frequency in the first __("#micro1").frequency(1200); //change the frequency in the second __("#micro2").frequency(600); //set the gain in both and start them __("microsynth").volume(1).start();

Generally, the goal of I Dropped My Phone The Screen Cracked is simplicity, brevity without obscurity and making audio coding as intuitive as patching a modular, so that noise makers can focus on keeping it weird and fun.

If you're interested in knowing more, there's a one page overview, full source documentation, a Reddit interview, some press, and a useful app for Mac or Linux to try it all out.

Also cat pictures.
