Reactive virtual acoustic environments (VAEs) that respond to any user-generated sound with an appropriate acoustic room response enable immersive audio applications with enhanced sonic interaction between the user and the VAE. This paper presents a reactive VAE that has two clear advantages in comparison to other systems introduced so far: it generally works with any type of sound source, and the dynamic directivity of the source is adequately considered in the binaural reproduction. The paper describes the implementation of the reactive VAE and completes the technical evaluation of the overall system focusing on the recently added software components. Regarding the use of the system in research, the study briefly discusses challenges of conducting psychoacoustic experiments with such a reactive VAE.
