安装 worker-loader版本是2.0.0
vue.config.js的配置如下

chainWebpack:(config)=>{config.output.globalObject("this");
},
configureWebpack: (config) => {config.module.rules.push({test: /\.worker.js$/,use: {loader: "worker-loader",options: { inline: true, name: "workerName.[hash].js" },},});
}

transcode.worker.js文件

// (function(){self.onmessage = function(e){transAudioData.transcode(e.data)}let transAudioData = {transcode(audioData) {let output = transAudioData.to16kHz(audioData)output = transAudioData.to16BitPCM(output)output = Array.from(new Uint8Array(output.buffer))self.postMessage(output)// return output},to16kHz(audioData) {var data = new Float32Array(audioData)var fitCount = Math.round(data.length * (16000 / 44100))var newData = new Float32Array(fitCount)var springFactor = (data.length - 1) / (fitCount - 1)newData[0] = data[0]for (let i = 1; i < fitCount - 1; i++) {var tmp = i * springFactorvar before = Math.floor(tmp).toFixed()var after = Math.ceil(tmp).toFixed()var atPoint = tmp - beforenewData[i] = data[before] + (data[after] - data[before]) * atPoint}newData[fitCount - 1] = data[data.length - 1]return newData},to16BitPCM(input) {var dataLength = input.length * (16 / 8)var dataBuffer = new ArrayBuffer(dataLength)var dataView = new DataView(dataBuffer)var offset = 0for (var i = 0; i < input.length; i++, offset += 2) {var s = Math.max(-1, Math.min(1, input[i]))dataView.setInt16(offset, s < 0 ? s * 0x8000 : s * 0x7fff, true)}return dataView},}
// })()

crypto-js如有需要安装
IatRecorder.js

import CryptoJS from "crypto-js";
import TransWorker from "@/components/speechRecognition/transcode.worker";
import { getWebsocket } from "@/api/websocket/websocket";
let transWorker = new TransWorker();
