Abstract: A method for pre-processing a channelized music signal to improve perception and appreciation for a hearing prosthesis recipient. In one example, the channelized music signal is a stereo input signal. A device, such as a handheld device, hearing prosthesis, or audio cable, for example, applies a mask to a stereo input signal to extract a center-mixed component from the stereo signal and outputs an output signal comprised of a weighted combination of the extracted center-mixed component and a residual signal comprising a non-extracted part of the stereo input signal. The center-mixed component may contain components, such as leading vocals and/or drums, preferred by hearing prosthesis recipients relative to other components, such as backing vocals or other instruments.

Abstract: A hearing system includes one or more hearing devices configured to be worn by a user. Each hearing device includes a signal source that provides an input electrical signal representing a sound of a virtual source. A filter implements a head related transfer function (HRTF) to add spatialization cues associated with a virtual location of the virtual source to the electrical signal and outputs a filtered electrical signal that includes the spatialization cues. A speaker of the hearing device converts the filtered electrical signal into an acoustic signal and plays the acoustic signal to the user. The system includes motion tracking circuitry that tracks motion of the user as the user moves in a direction of a perceived location that the user perceives to be the virtual location of the virtual source. Head related transfer function (HRTF) individualization circuitry determines a difference between the virtual location and the perceived location in response to the motion of the user.

Abstract: An apparatus and method are disclosed for providing output signal swings that are greater than the supply voltage in a class-D amplifier. The amplifier circuit boosts the voltage across the amplifier load, such as a loudspeaker, by using capacitors to “charge pump” the voltage across the load and thus increase the voltage temporarily. This is done by using two or more output bridges rather than one, and connecting the bridges through the capacitors. For signals of less than the supply voltage, only an inner bridge, similar to a full bridge of the prior art, operates. For signals above the supply voltage, an outer bridge charges capacitors, which are then used to ‘boost’ the voltage on the bridge output for the short period of the Class-D switching period. Thus, only relatively small value boosting capacitors are needed, as they do not need to supply charge for very long.

Abstract: A wireless earpiece may include a local memory for storing audio files that can be played back by the user. The wireless earpiece may fit entirely within the user's ear canal. Audio files, for example music files, may be loaded on the wireless earpiece by docking the wireless earpiece with a mobile device, which includes a larger memory storing the user's library of music files. The stored audio files may be received from a mobile device that were automatically selected from a library of music files by the mobile device without intervention from the user. To provide stereo sound, two wireless earpieces may be worn by the user and docked separately with the mobile device. Each of the two wireless earpieces may store a single channel of an audio file, which is separated by the mobile device during synchronization.

The audio assembly may use part of the shell and acoustically drive that part of the shell to generate the acoustical energy. Further, the audio assembly may use part of the flexible layer as a “surround” to allow part of the shell to move relative to other parts. The electronic device may electrically couple with the accessory device, thereby providing a means for providing an audio signal.

Abstract: Described are techniques for configuring a group of audio devices in communication with one another to provide an audio output. Test data may be communicated between a selected audio device and each audio device in the group to determine data throughput values for each communication. A value indicative of the airtime that would be used to communicate data to each audio device, using the selected audio device, may be determined. This process may be repeated for each audio device within the group. The selected audio device associated with the lowest airtime value may be designated as a master audio device. A maximum airtime value associated with distribution of audio data from the master audio device to the other devices may be determined based on the data throughput values for each device. If the maximum airtime value is less than a threshold airtime value, the audio data may be distributed.
