AB  - Virtual acoustic environments can aurally simulate an environment that is non-existent in reality. Achieving realistic and immersive audio in applications such as gaming and virtual reality (VR) requires high-quality virtual acoustic modelling. In real-time applications, the quality needs to be guaranteed while minimising computational cost. In this study, we generated two audio rendering systems with two stages of Freeverb: one with the full number of filters involved, and another with the half number of filters. An objective comparison analysis in acoustical difference and computational efficiency is conducted between results. A web-based ABX listening test is conducted as perceptual evaluation. The results indicate that, based on the proposed system, certain acoustic details are still overlooked in the identification of a single sound source in non-VR environments.
