Abstract: Soundfield signals such as e.g. Ambisonics carry a representation of a desired sound field. The Ambisonics format is based on spherical harmonic decomposition of the soundfield, and Higher Order Ambisonics (HOA) uses spherical harmonics of at least 2nd order. However, commonly used loudspeaker setups are irregular and lead to problems in decoder design. A method for improved decoding an audio soundfield representation for audio playback comprises calculating a panning function (W) using a geometrical method based on the positions of a plurality of loudspeakers and a plurality of source directions, calculating a mode matrix (?) from the loudspeaker positions, calculating a pseudo-inverse mode matrix (?+) and decoding the audio soundfield representation. The decoding is based on a decode matrix (D) that is obtained from the panning function (W) and the pseudo-inverse mode matrix (?+).

Abstract: A mobile device uses externals microphone signals to improve the estimate of background noise that it computes. In order to improve voice quality in a first signal that is produced by an internal microphone, the mobile device identifies an external microphone device within proximity of the mobile device. The mobile device establishes a wireless connection with the external microphone device. The mobile device receives a second signal from the external microphone device through the wireless connection. The second signal is produced by a microphone of the external microphone device. The mobile device generates a noise profile based on the second signal, and then suppresses background/ambient noise from the first signal based on the noise profile. Other embodiments are also described.

Abstract: An example implementation may involve a playback device assigning, to the playback device, a zone property that is assigned to a device base (e.g., a charging base) that the playback device is placed upon. For instance, a playback device may identify a particular base onto which the playback device is placed. The playback device may determine that the particular base is assigned a zone property that is associated with a first zone of a media playback system. The playback device may assign, to the playback device, the zone property that is assigned to the particular base. By acquiring the zone property, the playback device may join the first zone of the media playback system. Other example implementations may involve assigning a zone property to a device base, or modify a zone property of a device base, among other examples.

Abstract: The invention relates to a new audio transducer for mobile devices, in particular a micro speaker for use in mobile phones, tablets, gaming devices, notebooks or similar devices, that comprises two figure-8 shaped coils to compensate tumbling passively or to detect and compensate actively rocking modes of the membrane along the two axes perpendicular to the axis of piston-wise movement of the membrane using a detection coil and a damping coil per axis. An amplifier may be used to amplify the detection signal in order to increase the damping effect. Electrical rocking mode compensation replaces state of the art damping mechanisms which are based on damping materials added in the moving part of the membrane. Due to the independence of environmental conditions electrical damping outperforms existing damping techniques.

Abstract: A system and method of matching reverberation in teleconferencing environments. When the two ends of a conversation are in environments with differing reverberations, the method filters the reverberation so that when both signals are output at the near end (e.g., the audio signal from the far end and the sidetone from the near end), the reverberations match. In this manner, the user does not perceive an annoying difference in reverberations, and the user experience is improved.

Abstract: A method for providing tracking error signals in an optical data storage system includes a step of receiving a wobble signal having a first frequency from the wobble detection system. The wobble detection system includes an optical pick up unit that detects positions of the head relative to lands and grooves. Characteristically, the wobble signal is amplitude modulated for positions intermediate between the land and the groove.

The product signal is positive for a first direction of motion and negative for a second direction of motion that is opposite that of the first direction. The product signal is integrated to obtain a quadrature track error signal.

The apparatus may limit the mechanical excursion of the exciter to prevent physical damage to the exciter. The present invention also provides a method and apparatus for operating the audio exciter in a model vehicle.

Abstract: The overall performance and power utilization of an audio device may be improved with an adaptive sidetone generation system that generates sidetones optimized for different application-specific problems. In particular, systems that include sidetone generation capabilities may be developed to include numerous microphones from which information may be received and processed to generate optimized sidetones. For example, the information from the microphones may be used to receive and/or determine the audio device's operating mode. The information from the microphones and the received and/or determined mode may then be used to generate a sidetone that is optimized for the particular mode and particular conditions in which the audio device is operating. Through the generation of optimized sidetones, the audio signal quality may be improved, thus reducing the amount of subsequent audio processing required, and resulting in improved performance and power utilization.
