Comparative review of the surround speaker virtualizers on DSP platform

This paper reviews three DSP-based audio virtualizer implementations used in immersive audio technologies, which have transformed sound experiences with limited speaker setups. Focusing on key parameters such as memory usage, processing power, and input/output layouts, the study employs multi-criteria decision-making (MCDM) approach to evaluate each virtualizer's strengths and trade-offs. The findings provide insights into the efficiency and feasibility of these virtualizers in delivering high-quality immersive audio in resource-constrained environments.
