Tetra-Speaker: Continual Evaluation of the Immersive Experience of a Single-Point Reproduction System

In the first phase of experimentation, a tetra-speaker had been built as an efficient and compact system for the reproduction of individual sound sources. The reproduction process was based on the relationship of a single sound source, such as an instrument, and an acoustic space. This relationship focused on the radiating behavior of the source. In this paper the tetra-speaker is further evaluated in a case-like study on the immersive experience of the system with additional discussion of how the system may expand its usage to improve this experience within virtual environments. Professionals within the audio field were asked to give an expert’s opinion based on defined attributes of spatial impression and realism.
