An apparatus for outputting virtual sound, the apparatus comprising: a plurality of microphones (106, 310 to 313) configured to detect an audio signal originating from a sound source at a location in an environment; and a processor coupled to the one or more microphones, the processor configured to: determine a direct-to-reverberation ratio and a direction of arrival of the audio signal from the sound source in the environment; determine, based on the determined direct-to-reverberation ratio and direction of arrival of the audio signal, whether the sound source of the audio signal is located in a first zone of the environment or a second zone of the environment, the first zone being closer to the one or more microphones than the second zone; determine a location for a virtual sound source, wherein the determined location is different from the location of the sound source of the detected audio signal but is in the same zone of the environment as the sound source of the detected audio signal; and insert a virtual sound into the environment, wherein the inserted virtual sound has the virtual sound source at the determined location, wherein the inserted virtual sound has a direction of arrival based on the determined location of the virtual sound source and a reverberation characteristic which mimics the determined direct-to-reverberation ratio of the detected audio signal. a plurality of microphones (106, 310 to 313) configured to detect an audio signal originating from a sound source at a location in an environment; and a processor coupled to the one or more microphones, the processor configured to: determine a direct-to-reverberation ratio and a direction of arrival of the audio signal from the sound source in the environment; determine, based on the determined direct-to-reverberation ratio and direction of arrival of the audio signal, whether the sound source of the audio signal is located in a first zone of the environment or a second zone of the environment, the first zone being closer to the one or more microphones than the second zone; determine a location for a virtual sound source, wherein the determined location is different from the location of the sound source of the detected audio signal but is in the same zone of the environment as the sound source of the detected audio signal; and insert a virtual sound into the environment, wherein the inserted virtual sound has the virtual sound source at the determined location, wherein the inserted virtual sound has a direction of arrival based on the determined location of the virtual sound source and a reverberation characteristic which mimics the determined direct-to-reverberation ratio of the detected audio signal. determine a direct-to-reverberation ratio and a direction of arrival of the audio signal from the sound source in the environment; determine, based on the determined direct-to-reverberation ratio and direction of arrival of the audio signal, whether the sound source of the audio signal is located in a first zone of the environment or a second zone of the environment, the first zone being closer to the one or more microphones than the second zone; determine a location for a virtual sound source, wherein the determined location is different from the location of the sound source of the detected audio signal but is in the same zone of the environment as the sound source of the detected audio signal; and insert a virtual sound into the environment, wherein the inserted virtual sound has the virtual sound source at the determined location, wherein the inserted virtual sound has a direction of arrival based on the determined location of the virtual sound source and a reverberation characteristic which mimics the determined direct-to-reverberation ratio of the detected audio signal.
