Proposal to integrate AngeTheGreat's Engine Simulator into BeamNG.drive: The Future of Engine Sound BeamNG.drive is already the undisputed leader in vehicle deformation physics, but imagine if the sound simulation of its engines could reach the same level of realism. By integrating AngeTheGreat's engine simulator, we could not only transform the audio experience, but also open up incredible horizons for designers Why this integration? Currently, the engine sounds in BeamNG.drive are very good, but they're often based on samples or simplified models. Engine Simulator, on the other hand, generates sound in real time, based on extremely detailed physical calculations of the engine. This means that every component, every modification (turbo type, exhaust length, cam profile) has an authentic and dynamic influence on the sound. Integrating Engine Simulator would : Revolutionize Sound Realism: Engines would sound exactly as they would in real life, with nuances, specific noises (high/low frequencies) and incredible reactivity to every change of rpm or load. Gone are the generic sounds, replaced by the unique roar of each configuration. In AngeTheGreat's Engine Simulator, “procedural sound” is an approach to audio generation where the engine sound is not based on pre-existing recordings or audio samples, but is calculated and generated in real time from the physical simulation of the engine itself. How does it work? Imagine that the simulator doesn't play an .mp3 file of a running engine, but recreates the sound from scratch, based on the physics of what's going on inside the engine: Detailed Physical Simulation: Engine Simulator accurately simulates the internal processes of a combustion engine: Piston movement. Valve opening and closing. The combustion of the air/fuel mixture in each cylinder. The pressure waves created by the exhaust gases. Air flow in the intake. Converting physical phenomena into sound: Pressure waves generated by exhaust gases (which are vibrations in the air) are the main basis of sound. The simulator calculates the shape of these waves, their amplitude and frequency. These waves are then sent to a specialized audio engine. This audio engine applies various filters and effects that simulate how these waves would propagate in an exhaust system (resonance, muffler attenuation, etc.) and how they would be perceived by the ear. Additional noises (such as high-frequency turbo hiss or subtle mechanical noises, and low-frequency noises for engine rumble) are also dynamically generated and mixed. Real-time responsiveness: Since the sound is calculated on the fly, it reacts instantly to every change in the simulation: if you modify the throttle, engine speed, load, or even engine parameters (such as exhaust length in an .mr file), the sound adapts immediately and consistently with the physics. Why is it “Procedural” and what are the advantages? The term “procedural” comes from the fact that the sound is generated by “procedures” or algorithms that take parameters into account in real time, rather than by reading fixed data. Advantages of AngeTheGreat's procedural sound: Unmatched realism: This is the main advantage. The sound truly reflects the physical behavior of the engine, making listening incredibly authentic. Infinite variety: Even minor engine modifications in the .mr configuration file can produce a slightly different, unique sound, without the need to record new samples. Exceptional dynamics: The sound reacts extremely smoothly and precisely to changes in rpm, load and speed, without the clipping or repetitive loops sometimes heard with sample-based sounds. Flexibility for modding: Modders can create entirely new engines with unique physical characteristics, and Engine Simulator will generate the corresponding sound realistically, without the modder having to worry about audio recording. In short, the procedural sound in AngeTheGreat's Engine Simulator is what sets it apart and enables it to deliver a stunningly realistic engine aural experience, generating sound from the science of mechanics rather than simple recordings.
