Engines and motors feature heavily in video games, but they can be very problematic. As game car audio expert Greg Hill said, “For engine sounds most people think we just record a car and throw the sound into a folder and it magically just works in the game. Game sounds are interactive – unlike passive sound like movies where the sound is baked onto an audio track… sound has to be recorded a certain way so it can be decomposed and reconstructed into a ‘sonic model’ and linked to the physics so the player has full control over every parameter.”
And therein lies the issue; recorded sounds are fixed, but the game sounds need to be adaptable and controllable. One can get around this, but only with huge effort.
So Nemisindo (the Zulu word for Sound Effects, our start-up company) have brought their deep and advanced engine sound generator to Unity as an audio plugin.
The Nemisindo Engine implements a flexible, controllable and realistic engine for all your game vehicles. It is a Unity native audio plugin and can generate sound effects in real time, completely procedurally. The plugin offers an interactive interface with 14 parameters and 16 realistic presets (Formula One, monster truck, motorbike…). It also offers various functions to change the parameters of the sound effect at runtime. Hence the parameters can be linked to any in-game events which can lead to very organic and interesting results.
Here’s a demonstration video.
