  • Patent number: 10027290
    Abstract: A switchless pre-amplifier input circuit includes an audio input connector that receives a first audio device operable at a first impedance and a second audio device operable at a second impedance less than the first impedance. A preamplifier circuit outputs a preamplified audio signal in response to amplifying a first audio signal generated by the first audio device or a second audio signal generated by the second audio device. The switchless pre-amplifier input circuit further includes a impedance selector circuit that adjusts an impedance at the output to reach the second impedance in response to connecting the second audio device to the audio input connector and to adjust the impedance at the output to reach the first impedance in response to connecting the first audio device to the audio input.

  • Patent number: 9992597
    Abstract: Examples described herein involve validating motion of a microphone during calibration of a playback device. An example implementation involves a control device receiving an indication that the control device will begin detecting audio signals emitted from playback devices as part of a calibration process. While the control device is detecting audio signals emitted from the playback devices, the control device receives a stream of motion data indicating movement of the control device. The control device processes a first subset of the stream of motion data to determine that the first subset of the stream of motion data indicates sufficient horizontal translation of the control device occurred. Based on determining that the first subset of the stream of motion data indicates sufficient horizontal translation of the control device, the control device processes a second subset of the stream of motion data.

    Abstract: An audio customization system operates to enhance a user's audio environment. A user may wear headphones and specify what portion the ambient audio and/or source audio will be transmitted to the headphones or the personal speaker system. The audio signal may be enhanced by application of a spatialized transformation using a spatialization engine such as head-related transfer functions so that at least a portion of the audio presented to the personal speaker system will appear to originate from a particular direction. The direction may be modified in response to movement of the personal speaker system.

  • Patent number: 9948257
    Abstract: Phantom-powered inline preamplifiers capable of variable impedance loading are disclosed with unique adjustable interfaces. By enabling a user to adjust impedance loading from an actively-powered audio preamplifier which takes a microphone electrical signal or another sound source signal as an input, this unique audio preamplifier design with various adjustable impedance loading interface configurations can change sound characteristics according to the user's preference in a recording, production, or live concert environment. In addition, a high pass filter incorporated in a preamplifier with the variable impedance loading feature allows the user to further customize sound characteristics in the recording environment. This novel inline preamplifier, which may be standalone or integrated into a microphone casing, is powered via a microphone cable from a component (e.g. another preamplifier) providing the phantom power.
