js中pcm怎么转g711a编码？-灵析社区
001在vue项目里面通过navigator.mediaDevices.getUserMedia({ audio: true }).then((stream)采集到的音频，怎么转成G711A编码？网上找的都是java、C这些语言的，要么就是node写的客户端等等，没有看到关于纯js的
看数据的中二丸子头const audioContext = new AudioContext();
const source = audioContext.createMediaStreamSource(stream);
const buffer = await audioContext.decodeAudioData(await stream.getAudioTracks()[0].getBuffer());
const g711a = audioContext.createScriptProcessor(1024, 1, 1);
g711a.onaudioprocess = (event) => {
const input = event.inputBuffer.getChannelData(0);
const output = new Float32Array(input.length);
for (let i = 0; i 1) {
sample = 1;
}
output[i] = sample * 255;
}
event.outputBuffer.copyToChannel(output, 0);
};
source.connect(g711a);
g711a.connect(audioContext.destination);
