Summary

  • adds a local high-fidelity SoundFont rendering path using FluidSynth + MuseScore_General.sf2
  • adds make hifi-audio and tools/render_soundfont_preview.py
  • documents the rootless audio toolchain and limitations
  • includes the rendered 256 kbps MP3 artifact

Testing

  • python3 tests/validate_project.py
  • make hifi-audio
    • output: build/audio/hifi/memory-symphony-hifi.mp3
    • duration: 1668.000s
    • mean volume: -18.9 dB
    • max volume: -4.1 dB

Caveat

This is a SoundFont/General MIDI render, not a full sample-library mockup, but it is materially higher fidelity than the procedural synth because it uses real sampled instrument presets.

Local validation passed: python3 tests/validate_project.py and make hifi-audio. Rendered build/audio/hifi/memory-symphony-hifi.mp3 at 1668.000s, 256 kbps, mean -18.9 dB, max -4.1 dB. Forgejo Actions is pending at 'Waiting to run' because no runner has picked up the job, so I am proceeding with the requested repository update via rebase merge.
