Bug description
mm.parseBuffer throws error this.buf.copy is not a function

Expected behavior
correct execution

Any insight would be greatly appreciated.
The files underlying format, encoding, etc has been confirmed to be mp3.

    console.log('file :>> ', file);
      (async () => {
        try {
          const buffer = await file.arrayBuffer()
          console.log(buffer)
          const metadata = await mm.parseBuffer(file, 'audio/mpeg');
          console.log(metadata);
        } catch (error) {
          console.error(error.message);
        }
      })();

okey nvm I'm a fucking idiot - anyone has the same problem please refer to music-metadata-browser instead

It is an interesting error actually. If I understood well you tried to use directly music-metadata in your front-end application.

Apparently you manage to get a kind of working. I suspect Buffer got poly-filled with Uint8Array. The copy() does not exist in Uint8Array.

I am actually lately working toward a more multi purpose architecture, so replaced Buffer with Uint8Array where possible. (Ref: Borewit/token-types#246)

But indeed music-metadata-browse is the designed for the right adaptations to use music-metadata in a front-end application.
