LissajousJavaScript 音频性能工具
Lissajous 是一个 JavaScript 的实时音频的性能工具。它将创建震荡器和采样器的方法封装成 API,允许通过简单的数行代码提升歌曲的构建和即兴创作。
Lissajous 存在于 JavaScript 控制台中,专门为 Firefox 和 Chrome 所设计。
示例代码:
// make a triangle wave that loops the notes 69, 67, then 60 in quarter note intervals t = new track() t.tri().beat(4).notes(69,67,60) // load a sample, set the beat to quarter notes, set the note length to a half measure, // set the envelope to give it a little attack and release, and loop the notes 69, 67, then 60 s = new track() s.sample(buffer) s.beat(4).nl(8).adsr(0.1,0,1,1).notes(69,67,60) // load an array of three AudioBuffers called 'drums', play them in 8th notes and give them // the sequence drums[0], drums[2], drums[1], drums[2] d = new track() d.sample(drums) d.beat(2).sseq(0,2,1,2) // load a piano sample and mess it up real good p = new track() p.sample(pianoSample) p.beat(2).nl(2).speed(0.5).clamp(1/16).clshift(-1/16)
