What I s Procedural Audio? A Technical Primer

Procedura audio is a method of generating sound in real- time using algorithms rather than playing back pre- districtded or sampled audio files. In thee context of autonous vehicles, this means that every sound thee vehivele produces - frem the subtle hum of it presence to specific alert indicating an imminent turn - is syntetizale dynamicaly basen of internal parameters and external sensor data.
