AUDIO SYSTEM AND METHOD FOR OPERATION THEREOF Russian patent published in 2016 - IPC H04S3/00 G10L19/08 

FIELD: sound.

SUBSTANCE: invention relates to an audio system, particularly to virtual spatial reproduction of audio signals. Audio system comprises a receiver for receiving an audio signal, such as an audio object or a signal of a channel of a spatial multi-channel signal. Binaural circuit generates a binaural output signal by processing audio signal. Processing is representative of a binaural transfer function providing a virtual sound source position for audio signal. Measurement circuit generates measurement data indicative of a characteristic of acoustic environment, and a determining circuit determines an acoustic environment parameter in response to measurement data. Acoustic environment parameter may typically be a reverberation parameter, such as a reverberation time. Adaptation circuit adapts binaural transfer function dynamically in response to acoustic environment parameter. For example, adaptation may modify a reverberation parameter to more closely resemble reverberation characteristics of acoustic environment.

EFFECT: technical result is providing complete spatial audio perception on basis of binaural signals.
