有没有办法将 PCM 数据转换为其他流行的音频格式（如 mp3、wav 等）？

Question

所以我一直在尝试找到一种方法将 pcm 数据从VC ZF7B44CFFAFD5C52223D5498196C8A2E7BZ转换为 mp3/wav 之类的其他东西，但我找不到任何有用的东西，我试过这个 pcm 到 wav 转换器但它没有用，wav output 文件总是无缘无故地超过 300 小时，我也尝试使用 opus 数据而不是 pcm，因为这是一个选项，但这也不起作用。 如果需要，这是我的完整代码：

await message.member.voice.channel.join().then((connection) => {
  const receiver = connection.receiver.createStream(message.member, {
    mode: 'pcm',
    end: 'manual'
  })

  const writer = receiver.pipe(fs.createWriteStream(`./record-${message.author.id}.pcm`))

  var deniedtimer = setTimeout(async() => {
    await db.set(`shortholdtime-${message.author.id}`, true)
    writer.end()
    message.channel.send('Sorry, I stopped recording because your recording was over 30 minutes long! Because of this, your recording is going to be deleted in 10 minutes instead of 30. To stop you from abusing this system, you will not be able to use the record feature for another 15 minutes.')
    await db.set(`denyrecord-${message.author.id}`, 0)
    var deniedtimertime = setInterval(async() => {
      var deniedtimeleft = await db.get(`denyrecord-${message.author.id}`)
      if (deniedtimeleft >= 900) return async() => {
        clearInterval(deniedtimertime)
        await db.set(`denyrecord-${message.author.id}`, 'false')
      }
      await db.set(`denyrecord-${message.author.id}`, deniedtimeleft + 1)
    })
  }, 30 * 1000 * 60)

  writer.on('finish', async() => {
    if (message.member.voice.channel !== null) {
      message.member.voice.channel.leave()
    } else {
      var vcdata = await db.get(`vcdatarecord-${message.author.id}`)
      var vcdatachannel = message.guild.channels.cache.get(vcdata)
      vcdatachannel.leave()
    }
    clearTimeout(deniedtimer)
    var pcmData = fs.readFileSync(`./record-${message.author.id}.pcm`)
    var wavData = wavconvert.encodeWav(pcmData)
    fs.writeFileSync(`./record-${message.author.id}.pcm`, wavData)
    fs.renameSync(`./record-${message.author.id}.pcm`, `./record-${message.author.id}.wav`)
    if (await db.has(`shortholdtime-${message.author.id}`)) {
      message.channel.send('I finished recording because either I got disconnected, you left the voice chat or I forcibly stopped the recording. I attached the recording to this message. To play back your recording in a vc, use the command rplay. Your recording will be deleted in 30 minutes due to performance and privacy reasons (From my server, which means you won\'t be able to play the recording back but you will be able to listen to it via the attachment).')
      var attachment = new Discord.MessageAttachment(`./record-${message.author.id}.wav`)
      message.channel.send(attachment)
      setTimeout(() => {
        fs.unlinkSync(`./record-${message.author.id}.wav`)
      }, 30 * 1000 * 60)
    } else {
      setTimeout(() => {
        fs.unlinkSync(`./record-${message.author.id}.wav`)
      }, 10 * 1000 * 60)
    }
  })
  client.on('voiceStateUpdate', async(oldState, newState) => {
    if (oldState.channelID === null) return;
    if ((client.users.cache.get(oldState.id)).bot) return;
    if (!newState.channelID === null) return;
    await db.set(`vcdatarecord-${message.author.id}`, oldState.channelID)
    writer.close()
  })
})
