Abstract
A system for generating calibrated multi-channel non-coherent signals. The system comprises a plurality of synthesizers for generating a corresponding plurality of signals, and a plurality of filters for band-pass filtering the plurality of generated signals. Each filter filters the signal generated by one of the plurality of synthesizers, by performing the band-pass filtering in a dedicated frequency band. The system comprises a plurality of loudspeakers for playing the plurality of filtered signals respectively filtered by the plurality of filters. The system comprises a channel configurator for configuring at least one of the filters for performing the band-pass filtering according to a calibrated amplitude spectrum of the signal. The calibrated amplitude spectrum is determined based on a reference amplitude spectrum of the signal and at least one of the following parameters: a target global signal amplitude, a directionality of the signal when played by the corresponding loudspeaker, and a frequency response of the synthesizer.
