Abstract
A test platform (11) for facilitating the selection of a sound configuration that is suitable for a target audio system that has a limited processing power (Pmax). During an objective selection of the configurations, the platform (11) adopts—from among a set of possible configurations—the sound configurations that are compatible with the available power (Pmax) of the audio system. Next, the platform (11) makes it possible for an integrator to test the sound rendering of each configuration adopted by enabling the selection of the number of virtual loudspeakers and the order (14.2) of the HRTF filters. For this purpose, the integrator can select different types of sound sources to which to listen. After listening to the sound rendering of different sound configurations, the integrator can select the configuration that is most suitable to the target audio system.
