This article offers an overview of recent developments in both the acquisition and rendering of immersive audio. The audio acquisition section describes recent advances in microphone array processing, while the immersive audio rendering section highlights methods to synthesize a 3-D audio environment based on the HRTF. It discusses the method to move from headphone rendering to rendering with two loudspeakers using crosstalk cancellation. However, this article is very high level and general and the details of the implementation are not present.
