## What it is
A real-time internal combustion engine simulator that generates realistic engine audio and simulates engine response characteristics. It is an entertainment/demo application, not a scientific engineering tool.

## Use cases
- simulate realistic engine sounds in real time
- hear how different engine configurations sound
- play with engine throttle, gears, and clutch on a virtual dyno
- measure simulated horsepower and torque curves
- demo engine audio for videos or content creation

## When to choose
- you want realistic synthesized engine audio for entertainment or content
- you want to experiment with engine configurations and hear the result
- you want a fun interactive engine playground with dyno-style gauges

## When to avoid
- you need accurate engineering figures for real engine tuning or design
- you need a professional CAE/CFD engine simulation tool
- you need a polished product-grade application - the codebase was written as a demo

## Facets
- artifact type: application
- maturity: maintenance
- function: simulation, audio-processing, graphics
- domain: simulation, gaming-tools
- platform: windows, cpp
- tags: combustion-engine, engine-audio, real-time-simulation, dyno, game-simulator, audio, desktop
