Abstract: The invention is directed to systems, methods and computer program products associated with a microphone system for receiving a sound and producing an output signal representing the sound. The microphone system has a first microphone having a first dynamic range, the first microphone to receive the sound and produce a first sound signal based on the received sound. It also has a second microphone having a second dynamic range, the second microphone to receive the sound and produce a second sound signal based on the received sound, wherein the first dynamic range and the second dynamic range overlap thereby forming a transition dynamic range and processing logic operatively coupled to the first microphone and the second microphone. The processing logic is configured to receive the first sound signal from the first microphone, receive the second sound signal from the second microphone, and generate the output signal by combining the first sound signal and the second sound signal.

Abstract: A method includes determining a user's head size, forwarding information associated with the user's head size to a processing device. The method also includes identifying, by the processing device, a head-related transfer function (HRTF) associated with the user's head size or modifying, by the processing device, a HRTF based on the user's head size. The method further includes applying the identified HRTF or modified HRTF to audio signals to produce output signals, and forwarding the output signals to first and second speakers.

Abstract: A device may store a subset of a plurality of head-related transfer functions (HRTFs) for emulating stereo sound from a source in three-dimensional (3D) space, each of the HRTFs corresponding to a direction from which the stereo sound is perceived to arrive, by a user hearing the stereo sound. The device may also obtain a first direction from which first stereo sound is perceived to arrive, by the user and determine whether the subset of the plurality of HRTFs includes a first HRTF corresponding to the first direction, wherein the plurality of HRTFs include the first HRTF. Further, the device may select two HRTFs in the subset of the HRTFs, wherein directions that are associated with the two HRTFs are closer to the first direction than directions of other HRTFs in the subset of the HRTFs;

Abstract: A method of controlling audio recording using an electronic device and an electronic device are described. The electronic device comprises a microphone arrangement having a directivity pattern. A target direction relative to the electronic device is automatically determined in response to sensor data representing at least a portion of an area surrounding the electronic device. The microphone arrangement is automatically controlled in response to the determined target direction to adjust an angular orientation of the directivity pattern relative to the electronic device.
