Decoder for MP3

[frizurd]

Did you guys manage to find or create a decoder for MP3?

I tried using https://www.npmjs.com/package/audio-decode
I integrated the decoder this way:

            const decodeMP3 = async file => {
                const buffer = await decode(file)
                const data = {
                    "numberOfChannels": buffer.numberOfChannels,
                    "length": buffer.length,
                    "sampleRate": buffer.sampleRate,
                    "channelData": Array.from({ "length": buffer.numberOfChannels },
                        (_, ch) => buffer.getChannelData(ch))
                }
                return data
            }
            decoder.set("mp3", decodeMP3)
            decoder.set("m4a", decodeMP3)

But I am receiving the following error:

AssertionError [ERR_ASSERTION]: The expression evaluated to a falsy value:
  assert(
    audioBus.audioData.numberOfChannels === this.audioData.numberOfChannels,
  )
  ...
  generatedMessage: true,
  code: 'ERR_ASSERTION',
  actual: false,
  expected: true,
  operator: '=='
}
