var context = new AudioContext(),通过decodeAudioData获得声道数据并倒序一下即可
request = new XMLHttpRequest();
request.open('GET', 'path/to/audio.mp3', true);
request.responseType = 'arraybuffer';
request.addEventListener('load', function(){
context.decodeAudioData(request.response, function(buffer){
var source = context.createBufferSource();
Array.prototype.reverse.call( buffer.getChannelData(0) );
Array.prototype.reverse.call( buffer.getChannelData(1) );
source.buffer = buffer;
});
});
