  • Patent number: 9743187
    Abstract: A system for processing audio data of the present disclosure has an audio processing device for receiving audio data from an audio source. Additionally, the system has logic that separates the audio data received into left channel audio data indicative of sound from a left audio source and right channel audio data indicative of sound from a right audio source. The logic further separates the left channel audio data into primary left ear audio data and opposing right ear audio data and for separating the right channel audio data into primary right ear audio data and opposing left ear audio data applies a first filter to the primary left ear audio data, a second filer to the opposing right ear audio data, a third filter to the opposing left ear audio data, and a fourth filter to the primary right ear audio data, wherein the second and third filters introduce a delay into the opposing right ear audio data and the opposing left ear audio data, respectively.

  • Patent number: 9686609
    Abstract: A low power, digital audio interface includes support for variable length coding depending on content of the audio data sent from the interface. A particularized coding system is implemented that uses techniques of silence detection, dynamic scaling, and periodic encoding to reduce sent data to a minimum. Other techniques include variable packet scaling based on an audio sample rate. Differential signaling techniques are also used. The digital audio interface may be used in a headphone interface to drive digital headphones. A detector in the interface may detect whether digital or analog headphones are coupled to a headphone jack and drive the headphone jack accordingly.

  • Patent number: 9672805
    Abstract: A crosstalk cancelation technique reduces feedback in a shared acoustic space by canceling out some or all parts of sound signals that would otherwise be produced by a loudspeaker to only be captured by a microphone that, recursively, would cause these sounds signals to be reproduced again on the loudspeaker as feedback. Crosstalk cancelation can be used in a multichannel acoustic system (MAS) comprising an arrangement of microphones, loudspeakers, and a processor to together enhance conversational speech between in a shared acoustic space. To achieve crosstalk cancelation, a processor analyzes the inputs of each microphone, compares it to the output of far loudspeaker(s) relative to each such microphone, and cancels out any portion of a sound signal received by the microphone that matches signals that were just produced by the far loudspeaker(s) and sending only the remaining sound signal (if any) to such far loudspeakers.
