I want to record audio from Discord's audio channel in Node.js.

const { Client, GatewayIntentBits, Partials } = require('discord.js');
const { joinVoiceChannel, EndBehaviorType } = require('@discordjs/voice');
const fs = require('fs');
const { opus } = require('prism-media');
const wav = require('node-wav');

const client = new Client({
  intents: Object.values(GatewayIntentBits),
  partials: [Partials.Message, Partials.Channel, Partials.Reaction],
  rest: 60000
});
const prefix = '!';

client.once('ready', () => {
  console.log(`Logged in as ${client.user.tag}`);
});

client.on('messageCreate', async (message) => {
  if (message.content.startsWith(prefix + 'join')) {
    const voiceChannel = message.member?.voice.channel;
    if (!voiceChannel) {
      return message.reply('このコマンドを使用するには、音声チャンネルに参加している必要があります。');
    }

    const connection = joinVoiceChannel({
      channelId: voiceChannel.id,
      guildId: voiceChannel.guild.id,
      adapterCreator: voiceChannel.guild.voiceAdapterCreator,
      selfDeaf: false
    });

    connection.receiver.speaking.on('start', (userId) => {
      const audio = connection.receiver.subscribe(userId, {
        end: {
          behavior: EndBehaviorType.AfterSilence,
          duration: 100,
        },
      });

      const opusDecoder = new opus.Decoder({ channels: 1, rate: 48000, frameSize: 960 });
      const pcmData = [];

      opusDecoder.on('data', (chunk) => {
        pcmData.push(chunk);
      });

      opusDecoder.on('end', () => {
        const wavFileName = `./rec/${Date.now()}-${userId}.wav`;
        const wavData = wav.encode(pcmData, {
          sampleRate: 48000,
          float: false,
          bitDepth: 16,
          channels: 1,
        });
        fs.writeFileSync(wavFileName, wavData);
        console.log(`✅ Recorded ${wavFileName}`);
      });

      audio.pipe(opusDecoder);
    });
  }
});

const { Client, GatewayIntentBits, Partials } = require('discord.js');
const { joinVoiceChannel, EndBehaviorType } = require('@discordjs/voice');
const fs = require('fs');
const { opus } = require('prism-media');
const wav = require('node-wav');

const client = new Client({
  intents: Object.values(GatewayIntentBits),
  partials: [Partials.Message, Partials.Channel, Partials.Reaction],
  rest: 60000
});
const prefix = '!';

client.once('ready', () => {
  console.log(`Logged in as ${client.user.tag}`);
});

client.on('messageCreate', async (message) => {
  if (message.content.startsWith(prefix + 'join')) {
    const voiceChannel = message.member?.voice.channel;
    if (!voiceChannel) {
      return message.reply('このコマンドを使用するには、音声チャンネルに参加している必要があります。');
    }

    const connection = joinVoiceChannel({
      channelId: voiceChannel.id,
      guildId: voiceChannel.guild.id,
      adapterCreator: voiceChannel.guild.voiceAdapterCreator,
      selfDeaf: false
    });

    connection.receiver.speaking.on('start', (userId) => {
      const audio = connection.receiver.subscribe(userId, {
        end: {
          behavior: EndBehaviorType.AfterSilence,
          duration: 100,
        },
      });

      const opusDecoder = new opus.Decoder({ channels: 1, rate: 48000, frameSize: 960 });
      const pcmData = [];

      opusDecoder.on('data', (chunk) => {
        pcmData.push(chunk);
      });

      opusDecoder.on('end', () => {
        const wavFileName = `./rec/${Date.now()}-${userId}.wav`;
        const wavData = wav.encode(pcmData, {
          sampleRate: 48000,
          float: false,
          bitDepth: 16,
          channels: 1,
        });
        fs.writeFileSync(wavFileName, wavData);
        console.log(`✅ Recorded ${wavFileName}`);
      });

      audio.pipe(opusDecoder);
    });
  }
});

I did this but it saves a corrupt wav file. What do you think I should do?

I did this, but still only noise is recorded.

    }

    const connection = joinVoiceChannel({

        },
      });
      var filename = './rec/'.concat(Date.now(), '-').concat(userId, '.pcm');
      var out = fs.createWriteStream(filename);
      stream.pipeline(audio, out, function (err) {
        if (err) {
          console.warn(`❌ Error recording file ${filename} - ${err.message}`);
