A first apparatus performs the following: determining, using microphone signals corresponding to a left microphone signal from a left microphone and a right microphone signal from a right microphone and using at least one further microphone signal, directional information of the left and right microphone signals corresponding to a location of a sound source; outputting a first signal corresponding to the left microphone signal; outputting a second signal corresponding to the right microphone signal; and outputting a third signal corresponding to the determined directional information. A second apparatus performs the following: determining, using microphone signals corresponding to a left microphone signal from a left microphone and a right microphone signal from a right microphone and using at least one further microphone signal, directional information of the left and right microphone signals corresponding to a location of a sound source; converting the left microphone signal, the right microphone signal and the directional information into a high quality left microphone signal and a high quality right microphone signal; and outputting a first signal corresponding to the high quality left microphone signal; and outputting a second signal corresponding to the high quality right microphone signal. Additional apparatus, program products, and methods are disclosed.
A method, comprising, determining, using microphone signals corresponding to a left microphone signal from a left microphone and a right microphone signal from a right microphone and using at least one further microphone signal, directional information of the left and right microphone signals corresponding to a location of a sound source;
A method comprising, receiving, by a processor, a first signal corresponding to a left microphone signal from a left microphone, a second signal corresponding to a right microphone signal from a right microphone, and a third signal corresponding to a sign of directional information of the left and right microphone signals determined using at least one further microphone signal and corresponding to a location of a sound source, wherein the sign is transmitted as a binary value that indicates the sound source coming from behind or in front of the left microphone and the right microphone, wherein the processor generates an audio output signal dependent on the sign of the directional information.
A method, comprising, determining, using microphone signals corresponding to a left microphone signal from a left microphone and a right microphone signal from a right microphone and using at least one further microphone signal, directional information of the left and right microphone signals corresponding to a location of a sound source;
A method comprising receiving, by a processor, a first signal corresponding to a high quality directional audio coding left microphone signal determined from a left microphone, and a second signal corresponding to a high quality directional audio coding right microphone signal determined from a right microphone, where the high quality directional audio coding left microphone signal and the high quality directional audio coding right microphone signal are based on directional information of left and right microphone signals determined using at least one further microphone signal and corresponding to a location of a sound source, wherein the processor generates an audio output signal dependent on the directional information.
