• Bug Fixes
  • Improved handling of certain WAV files during audio encoding checks, reducing the chance of misreading header bytes and rejecting valid files.

Walkthrough

The wav_header buffer in check_for_invalid_wav_formats was changed from char[44] to unsigned char[44], with both infile.read calls updated to use an explicit (char*) cast to match the new buffer type.

Poem

A little buffer, once signed and shy,
Now wears unsigned bytes, standing tall and spry.
Two reads recast with a careful hop,
This rabbit thumps its paw — bug-fix, non-stop! 🐇
