This interactive sound effects synthesizer generates authentic 8-bit arcade audio directly in your browser using the browser's native Web Audio API. Inspired by classic Nintendo Entertainment System (NES) and Game Boy sound chips (such as the Ricoh 2A03), it synthesizes waveforms in real time without prerecorded sample audio files.

### Waveform Synthesis & Oscillator Models The generator models four distinct chiptune sound archetypes using programmable oscillator nodes and exponential gain envelopes:

- **Retro Coin (Arcade Ding):** Uses a clean sine oscillator producing two sequential tones: an initial $987.77\text{ Hz}$ pitch (musical note B5) that jumps to $1318.51\text{ Hz}$ (musical note E6) after $0.08\text{ seconds}$, recreating classic platformer coin pickup alerts. - **8-Bit Jump (Platformer Hop):** Uses a square oscillator starting at $150\text{ Hz}$ and sweeping up exponentially to $600\text{ Hz}$ over $0.15\text{ seconds}$ to emulate a rising character hop. - **Laser Zap (Space Shooter):** Uses a sharp sawtooth oscillator initiating at $800\text{ Hz}$ and decaying downward exponentially to $80\text{ Hz}$ over $0.15\text{ seconds}$ to create high-velocity blaster beams. - **Explosion (Damage Hit):** Uses a low square oscillator starting at $200\text{ Hz}$ that drops rapidly to a sub-bass rumble of $40\text{ Hz}$ over $0.25\text{ seconds}$ with a decaying gain envelope.

### Concrete Sound Parameters Every synthesized sound routes through an exponential gain decay node: 1. Gain begins at an amplitude of $0.3$ upon key trigger. 2. Amplitude decays exponentially to $0.001$ over $0.20\text{ seconds}$. 3. The oscillator stops execution at $0.25\text{ seconds}$, freeing hardware audio buffers.

### Client Audio Execution Guarantee All sound effects synthesize natively in client hardware via `window.AudioContext` and the Web Audio API. Zero audio MP3/WAV files are fetched from external CDNs, and zero listening logs or sound triggers are sent across a network.
