WAU

Simple WebAudio API Utility

Description

• WAU is a WebAudio API library, which facilitate control sound sources and connect WebAudio API's AudioNodes easily.

Examples

var node = new WAU({
     path : "./source",
     source : ["sound1.mp3"[, ... ]]
 });
 
 node.src("sound1.mp3").play(true);  // for loop play
 node.src("sound1.mp3").plug("biquad", { type:0, frequency:500, Q:10 }).play();
 node.src("sound1.mp3").plug("biquad", { type:0, frequency:500, Q:10 }).plug("compressor").play();
 
 // When attempt to get source which isn't in buffer yet, load it to the buffer and throw with error message for the next attempt.
 node.src("sound2.mp3")        // error in first attempt
 node.src("sound2.mp3").play() // ok for next attempt
 
 node.src("sound2.mp3").stop() // stop playing

Methods

• .src(string) // Get(or load) the audio source.
• .plug(string) // Plug the source with the indicated AudioNode. (Check the available list of nodes below)
• .volume(number) // Set the volume.
• .biquad({...}) // Set the biquadFilter value if the source was connected.
• .play() // Play audio source.
• .stop() // Stop playing source.
• .getBufferList() // Get decoded audio source in buffer memory.

List of nodes

• compressor

• biquadFilter

node.src("sound.mp3").plug("biquad", {
     type : 0,
     frequency : 1000,
     Q : 10
}).play();

• convolver

node.src("sound.mp3").plug("convolver", "convolver_sound.mp3").play();

• javascript

node.src("sound.mp3").plug("javascript", function(e) {
     var nChannel = e.inputBuffer.numberOfChannels;
    
     for(var i=0, aBuffer; i < nChannel;i++) {
          console.log(e.inputBuffer.getChannelData(i));
     }
}).play();
