Do you want to download the audio files you receive or the voice messages you receive? (these are two different types of messages)

client.on('message', async msg => {
  if(msg.hasMedia){
    const media = await msg.downloadMedia();
    var mediaType = media.mimetype;
    if(mediaType.indexOf("audio/ogg") >= 0){
      var media_filename = "export-voice.ogg"; 
      var media_source = "data:"+media.mimetype+";base64,"+media.data;
      media_source = media_source.replace('data:audio/ogg; codecs=opus;base64,', '');
      media_source = media_source.replace(/ /g, '+');
      var media_base64 = Buffer.from(media_source, 'base64');
      files.writeFileSync("/path/to/files/"+media_filename, media_base64);
    }
  }
});

This simple code checks whether the received message contains media and if the type is audio/ogg (which is the type used by voice messages) proceeds to save the file in the directory selected by you.

Did you define messagemedia at the beginning of your project?
const { MessageMedia } = require('whatsapp-web.js');
You can also define the Client in the same line for cleaner code
const { Client, MessageMedia } = require('whatsapp-web.js');
