Summary

  • Add getMP3() and getWAV() methods to export scores as audio files (MP3 and WAV formats)
  • Add exportProgress event for tracking audio rendering progress
  • Increase Karma browser timeout to 3 minutes to accommodate audio export tests

Test plan

  • Unit tests verify getMP3() and getWAV() methods exist and return Promises
  • Integration tests validate MP3/WAV output with magic byte checks
  • Integration test confirms exportProgress events fire during export
  • Run pnpm test to verify all tests pass

🤖 Generated with Claude Code

Add audio export capabilities with MP3 and WAV formats, along with
an exportProgress event for tracking rendering progress.
