  • Patent number: 10795496
    Abstract: It is intended to provide a method for selecting a writing sheet for a touch panel pen that can accurately select a writing sheet with which the generation of unpleasant sounds during writing is suppressed. According to the method for selecting a writing sheet for a touch panel pen, a sheet satisfying condition 1-1 and condition 1-2 described below is selected as a writing sheet for a touch panel pen. <condition 1-1> Sound generated when writing is performed under predetermined conditions using a touch panel pen on the surface of a writing sheet for a touch panel pen is recorded. The sound pressure (dB/Hz) is calculated for each 1 Hz from the recorded sound by means of fast Fourier transform. The values of the dB/Hz at frequencies from 1 Hz to 20,000 Hz are normalized to have a maximum value of 100 and a minimum value of 0, and the normalized values of dB/Hz are adopted as rated sound pressures P.

  • Patent number: 10789947
    Abstract: Audio information defining audio content may be accessed. The audio content may have a duration. The audio content may be segmented into audio segments. Individual audio segments may correspond to a portion of the duration. Feature vectors of the audio segments may be determined. The feature vectors may be processed through a classifier. The classifier may output scores on whether the audio segments contain voice. One or more of the audio segments may be identified as containing voice based on the scores and a two-step hysteresis thresholding.

  • Patent number: 10785569
    Abstract: Dynamic loudness equalization of received audio content in a playback system, using metadata that includes instantaneous loudness values for the audio content. A playback level is derived from a user volume setting of the playback system, and is compared with a mixing level that is assigned to the audio content. Parameters are computed, that define an equalization filter that is filtering the audio content before driving a speaker with the filtered audio content, based on the instantaneous loudness values and the comparing of the playback level with the assigned mixing level. Other embodiments are also described and claimed.

  • Patent number: 10770082
    Abstract: There is provided an audio decoder and a method therein for transforming a digital audio signal from a first frequency domain to a second frequency domain. For each received frame of the digital audio signal, the method identifies an upper limit of the frequency range, and if the upper limit of the frequency range is below the Nyquist frequency of said frame of the digital audio signal by more than a threshold amount, the Nyquist frequency of said frame of the digital audio signal is lowered from its original value to a reduced value by removing spectral bands of said frame of the digital audio signal above the identified upper limit of the frequency range. Thereafter said frame of the digital audio signal is transformed from the first frequency domain to the second frequency domain via an intermediate time domain.

  • Patent number: 10749488
    Abstract: A multi-channel switchmode audio amplifier is configured by a programmed processor such that each channel drives separate loads, is connected in parallel or is configured in a bridge-tied mode as well as combinations thereof. In one embodiment, amplifier channels that are connected in parallel have power amplifiers that are driven with signals from a single modulator. A feedback circuit and error amplifier from one channel controls the modulated signal that is applied to each parallely connected amplifier channel. Current feedback circuits for parallely connected amplifier channels are eliminated by tightly controlling the timing of switching in the power amplifier output stages.

  • Patent number: 10748228
    Abstract: System that enables a user to generate a detailed noise complaint with a simple input such as a button click; the system identifies the source of the noise and the authority responsible for monitoring this noise, and it creates a properly formatted complaint and sends it to the responsible authority. Illustrative uses include generation of complaints for noise caused by air traffic, trains, wind turbines, road traffic, or sirens. The user may initiate a complaint using any device such as a mobile phone, a voice-activated system such as Amazon Echo™ or Google Home™, or a dedicated input device. The system may search databases or information feeds to identify the likely source of noise near the user's location. For example, the system may access real-time flight path data to find the airplane closest to the user at the time the user initiates an air noise complaint.

  • Patent number: 10735887
    Abstract: A spatial audio processing system operable to enable audio signals to be spatially extracted from, or transmitted to, discrete locations within an acoustic space. Embodiments of the present disclosure enable an array of transducers being installed in an acoustic space to combine their signals via inverting physical and environmental models that are measured, learned, tracked, calculated, or estimated. The models may be combined with a whitening filter to establish a cooperative or non-cooperative information-bearing channel between the array and one or more discrete, targeted physical locations in the acoustic space by applying the inverted models with whitening filter to the received or transmitted acoustical signals. The spatial audio processing system may utilize a model of the combination of direct and indirect reflections in the acoustic space to receive or transmit acoustic information, regardless of ambient noise levels, reverberation, and positioning of physical interferers.

  • Patent number: 10728692
    Abstract: Embodiments are directed to upward-firing speakers that reflect sound off a ceiling to a listening location at a distance from a speaker. The reflected sound provides height cues to reproduce audio objects that have overhead audio components. A virtual height filter based on a directional hearing model is applied to the upward-firing driver signal to improve the perception of height for audio signals transmitted by the virtual height speaker to provide optimum reproduction of the overhead reflected sound. The upward firing driver is tilted at an inclination angle of approximately 20 degrees to the horizontal axis of the speaker and separate height and direct terminal connections are provided to interface to an adaptive audio rendering system.
