Gibber is a live coding environment for the web browser, using the Gibberish audio engine and the CodeMirror code editor. It runs in Chrome and recent builds of Safari (iOS 6 and higher, or Safari 6 and higher on desktop). To run, Gibber needs to be accessed from a web server. In OS X you can do this by simply turning on Web Sharing under System Preferences and placing the Gibber directory in your Sites folder. Then access Gibber using the URL 127.0.0.1/~yourusername/gibber/index.htm.
Below is a code sample. To test out Gibber, visit http://www.charlie-roberts.com/gibber
Gibber.setBPM(180); // default = 120. You can also refer to Gibber as _g.
s = Sine(240, .25); // Sine wave with freq 240, amp .5.
s.fx.add( // create an fx chain for oscillator
Clip(50), // Soft-Clip Distortion
Delay(_16) // Delay with delay time set to 1/4 of a beat (1/16th note)
);
a = Arp("C2m7", _16, "updown", 3); // Arpeggiator: Cminor7 chord in 2nd octave, 16th notes, up then down, 3 octave range
d = Drums("x*o-x*o-", _8);
d.chain( Crush(6) );
d.pitch = 2; // play drum sapmles at twice their normal pitch
s.mod("frequency", LFO(8, 4), "+"); // Vibrato - modulating frequency by +/- 4Hz 8 times per second
s.removeMod(0);
a.shuffle(); // randomize arpeggio
a.reset(); // reset arpeggio
Master.fx.add( Schizo(), Reverb() ); // Master FX are applied to summed signal of all generators
Master.removeFX(0); // remove first effect in chain. don't pass a argument to remove all fx.Gibber also relies on Sink.js, audiofile.js, require.js and jQuery for functionality.
