Incorrect metadata for mp3 file

See original GitHub issue

I’ve got incorrect data while using parseBlob function with .mp3 extension audio file.

Input audiofile:

Steps to reproduce:

  1. upload mp3 file from zip
  2. use function parseBlob or parseFile (from music-metadata) for file


codec: "MP2"
numberOfChannels: 2
sampleRate: 16000

Expected: (as f.e. resolves it)

codec: "MP3"
numberOfChannels: 1
SampleRate: 8000

71 warnings while parsing file:

  • 64 warnings - "Parse error: Cannot determine bit-rate"
  • 5 warnings - "Parse error: Cannot read property 'toString' of null",
  • 2 warnings - "Parse error: Cannot determine sampling-rate"

Issue repeats in library music-metadata too. Hope, you may help clarify things for me or find a fix for this.
