## Original generated voices and effects

The short cartoon voice lines were generated locally from original text with [Kokoro v1.0](https://huggingface.co/hexgrad/Kokoro-82M), whose model weights are Apache-2.0 licensed. Stock voice: `bm_george`, language `en-gb`, speed 1.1; pitch raised 9 semitones, high-pass at 130 Hz, low-pass at 8.5 kHz. No original game recording or voice clone was used. These voices are AI-generated.

Authoring tools: kokoro-onnx 0.6.1 (MIT), ONNX Runtime 1.29.0, Pedalboard 0.9.24, SciPy, NumPy and SoundFile. These tools and model files are not shipped with the game and are not required for playback.

Gunshots, movement squeaks and splash are original deterministic procedural synthesis: decaying filtered noise and sine/harmonic components, seeded with 43821. All game WAVs are mono, 24 kHz, 16-bit PCM, normalized to a maximum absolute amplitude of 0.78 with short edge fades. Some recordings are shortened for a single game event.

## Choral cue

`holygrenade.wav` is a 2.35-second extract from the Edison/Oratorio Chorus recording of Handel’s *Messiah*, May 1916, matrix 4433-A-1-1 (6-1), listed as public domain by Wikimedia Commons. It is a different recording from the original game’s sound. The source’s 8.25–10.6-second interval was filtered at 200 Hz–4.3 kHz and normalized. This historical recording and the initial voice direction remain subject to listening feedback. The simulation’s explicit chant delay matches the bundled clip length.
