Abstract: A first apparatus performs the following: determining, using at least two microphone signals corresponding to left and right microphone signals and using at least one further microphone signal, directional information of the left and right microphone signals; 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. Another apparatus performs the following: performing at least one of the following: outputting first and second signals as stereo output signals; or converting the first and second signals to mid and side signals, and converting, using directional information for the first and second signals, the mid and side signals to at least one of binaural signals or multi-channel signals, and outputting the corresponding binaural signals or multi-channel signals. Additional apparatus, program products, and methods are disclosed.

Abstract: A mobile platform includes a microphone array and is capable of implementing beamforming to amplify or suppress audio information from a sound source. The sound source is indicated through a user input, such as pointing the mobile platform in the direction of the sound source or through a touch screen display interface. The mobile platform further includes orientation sensors capable of detecting movement of the mobile platform. When the mobile platform moves with respect to the sound source, the beamforming is adjusted based on the data from the orientation sensors so that beamforming is continuously implemented in the direction of the sound source. The audio information from the sound source may be included or suppressed from a telephone or video-telephony conversation. Images or video from a camera may be likewise controlled based on the data from the orientation sensors.
