Developments in immersive audio technolo- gies have been evolving in two directions: physically- motivated and perceptually-motivated systems. Physically motivated techniques aim to reproduce a physically ac- curate approximation of desired sound fields by employ- ing a very high equipment load and sophisticated com- putationally intensive algorithms. Perceptually-motivated techniques, on the other hand, aim to render only the perceptually relevant aspects of the sound scene by means of modest computational and equipment load. This article presents an overview of perceptually motivated techniques, with a focus on multichannel audio recording and repro- duction, audio source and reflection culling, and artificial reverberators.
