Abstract (en)

An audio apparatus, e.g. for a virtual reality client, comprises a receiver (201) for receiving a set of input audio signals from a first source; a receiver (203) for receiving acoustic environment data from a second source; and a receiver (205) for receiving binaural transfer function data from a third source where the binaural transfer function data is indicative of a set of binaural transfer functions. A renderer (207) generates output audio signals from the set of input audio signals. A reverberator generates a reverberation component of the output audio signals by applying reverberation processing to the set of input audio signals in response to the acoustic environment data, and an adapter (211) adapts a first property of the reverberation processing in response to a second property of the set of binaural transfer functions. The acoustic environment data and binaural transfer function data may be received from different sources.
