Audio device and operation method thereof

An audio device comprises a receiver (501) that receives audio data and metadata comprising data for reverberation parameters for an environment. A modifier (503) generates a modified first parameter value for a first reverberation parameter, the first reverberation parameter being a reverberation delay parameter or a reverberation attenuation rate parameter. A compensator (505) generates a modified second parameter value for the second reverberation parameter in response to the modification of the first reverberation parameter. The second reverberation parameter is indicative of reverberation energy in the acoustic environment. The renderer (400) generates the audio output signals by rendering the audio data using the metadata, and in particular, the reverberation renderer (407) generates at least one reverberation signal component for at least one audio output signal from at least one of the audio signals in response to the first modified parameter value and the second modified parameter value. The compensa
