Issue description

   	const attachments = this.options.files?.map((file, index) => ({
   	id: index.toString(),

      waveform: file.waveform
    }));

import getAudio from 'get-audio-duration';

await interaction.channel.send({ files: [
        {
          attachment: "/local/audio/audio.mp3",
          name: 'audio.mp3',
          contentType: 'audio/mp3',
          waveform: new Buffer(new Uint8Array([1,2,3])).toString("base64"),
          //@ts-ignore
          duration_secs: await getAudio("/local/audio/audio.mp3")
        }
      ],
