我正在使用以下方法来播放包含wav数据的字节数组.该函数正在从GWT项目中调用.

此功能播放声音,但它听起来像某种地狱怪物.采样率肯定是正确的(声音是由neospeech生成的)我已经为numberOfSamples尝试了各种值,这似乎只代表音频数据的长度.

numberOfSamples的值大于30000将播放音频文件的全长,但它是乱码且可怕的.

那么,我做错了什么？

function playByteArray(byteArray, numberOfSamples) {

sampleRate = 8000;

if (!window.AudioContext) {

if (!window.webkitAudioContext) {

alert("Your browser does not support any AudioContext and cannot play back this audio.");

return;

}

window.AudioContext = window.webkitAudioContext;

}

var audioContext = new AudioContext();

var buffer = audioContext.createBuffer(1, numberOfSamples, sampleRate);

var buf = buffer.getChannelData(0);

for (i = 0; i < byteArray.length; ++i) {

buf[i] = byteArray[i];

}

var source = audioContext.createBufferSource();

source.buffer = buffer;

source.connect(audioContext.destination);

source.start(0);

}
