我已经开始尝试使用Web Audio API
创建一个可在React中使用的录音机这是我的Recorder类的代码
import AudioNode from './workletNode'
export default class Recorder {
constructor(context) {
this.context = context
this.recording = false
console.log(context)
context.audioWorklet.addModule('processor.js')
.then(() => {
console.log('added worklet module')
navigator.mediaDevices.getUserMedia({audio: true, video: false})
.then(stream => {
console.log('Have stream')
let microphone = context.createMediaStreamSource(stream)
let wavEncoder = new AudioNode(context)
microphone.connect(wavEncoder).connect(context.destination)
})
})
.catch((e) => {
alert('Error getting audio')
console.log(e)
})
}
record() {
console.log('Start recorder')
this.recording = true
}
stop() {
console.log('Stop recorder')
this.recording = false
}
}
我遇到的问题是与此行:context.audioWorklet.addModule('processor.js')
没有添加processor.js文件。
,然后在到达此行时引发错误:
let wavEncoder = new AudioNode(context)
错误是:
未处理的拒绝(TypeError):__WEBPACK_IMPORTED_MODULE_0__workletNode ___ default.a不是构造函数
我已经在react之外尝试了相同的代码,这很好。因此,这与在react中使用audioWorklet.addModule
有关。
有人可以帮忙吗?
这是调用记录器的react组件:
import React from 'react'
import {connect} from 'react-redux'
import {Button} from 'semantic-ui-react'
import {injectIntl} from 'react-intl'
import Recorder from './recorder'
class SpeechToTextAudioWorklet extends React.Component {
componentDidMount() {
this.context = null
this.recorder = null
}
startRecorder() {
if (!this.context) {
this.context = new window.AudioContext()
this.recorder = new Recorder(this.context)
} else {
this.context.resume()
}
this.recorder && this.recorder.record()
}
stopRecorder() {
this.recorder && this.recorder.stop()
}
render() {
return (<div>Speech to text
<Button id="start" onClick={() => {
this.startRecorder()
}}>Record</Button>
<Button id="stop" onClick={() => {
this.stopRecorder()
}}>Stop</Button>
<div id="recordingslist"></div>
</div>)
}
}
const mapStateToProps = () => {
return {}
}
export default connect(
mapStateToProps
)(injectIntl(SpeechToTextAudioWorklet))
答案 0 :(得分:0)
尝试在worklet
文件夹中建立一个public
目录,将AudioWorkletProcesser移到那里,然后更改代码以反映新路径:context.audioWorklet.addModule('worklet/processor.js')
。
