# QUAD GOD audio: licences

**Every file in `assets/audio/` is original work synthesised by our own code** (`tools/audio/*.py`, numpy + scipy) and encoded with ffmpeg (LAME MP3, libvorbis). There are **no samples, no field recordings, no sound libraries, no third-party or AI-generated audio** (no Mai studio, Replicate, ElevenLabs or Freesound material) in this set. Cost: $0.

- **Ownership:** the project owns the audio outright; no attribution or licence terms attach to it. The code that renders it is in this repo.
- **Tools:** numpy and scipy (BSD-3) for synthesis; ffmpeg via imageio-ffmpeg (LGPL/GPL build) used only as an encoder/meter. Encoders and libraries place no restriction on their output.
- **Melodies and progressions:** written for QUAD GOD by the audio agent. The IP rule was followed: no Korobeiniki or any Russian-folk melody, no recognisable melody from any game or company (Nintendo, Sega, Capcom, …). Generic chiptune devices (pulse arpeggios, a falling whistle, a two-tone alarm, a boxing-style bell) are idioms, not quotations. The coin ding is a triad flick (root–3rd–5th into a ringing top note), deliberately not the classic "B → E" coin interval; the win fanfares avoid the repeated-note triplet victory figure.
- **Fonts on the listening page:** Silkscreen and Press Start 2P (OFL), from `fonts/`.
