    Abstract: One or more accelerometers embedded with an earbud and/or a set of earphones are able to sense a moving pace of a user. Based on a moving pace of the user, a signal is sent to a remotely connected electronic device. The electronic device is able to separately increase and decrease a beat or rhythm of the audio from the electronic device based on a pace of the user. In some embodiments, an audio alert is sent to the user to inform the user of pace and whether the user has increased or decreased their pace. Additionally, in some embodiments, a program stored on the electronic device is used to compare the user's current progress and/or speed based on past runs and workouts.

  • Patent number: 10219072
    Abstract: A dual microphone near field voice enhancement arrangement in a motor vehicle includes a seat having a headrest with two opposite lateral sides. Each of two microphones is mounted on a respective one of the two opposite lateral sides of the headrest. Each microphone produces a respective microphone signal indicative of sounds within a passenger compartment. An electronic processor receives the microphone signals. The processor calculates a time delay between the microphone signals, and uses the calculated time delay to estimate amplitudes of the microphone signals. The processor applies a respective time delay to each of the microphone signals based on the calculated time delay to produce two time-aligned signals. The processor applies a respective gain to each of the time-aligned microphone signals based on the estimated amplitudes to produce two time-aligned and gain corrected signals. The processor sums the time-aligned and gain corrected signals.

  • Patent number: 10200805
    Abstract: Embodiments herein relate generally to changing spatial audio fields that are defined for audio sources. In the embodiments, the spatial audio fields are indicated to a user performing audio mixing, for instance by displaying them as polygons on a touch screen. The spatial audio fields move as the related audio sources move, and/or as the position of a notional consumer changes. Apparatus of the embodiments is configured to detect whether at any time (initially, or after movement) there is overlapping of two spatial audio fields. If an overlap is detected, this is indicated to a user performing audio mixing The apparatus then responds to a user input (e.g. a gesture on the touch screen) by detecting the nature of the user input and then moving or sizing one or both of overlapping spatial audio fields and such that overlapping is avoided or reduced.

    Abstract: A method for compressing a HOA signal being an input HOA representation with input time frames (C(k)) of HOA coefficient sequences comprises spatial HOA encoding of the input time frames and subsequent perceptual encoding and source encoding. Each input time frame is decomposed (802) into a frame of predominant sound signals (XPS(k?1)) and a frame of an ambient HOA component ({tilde over (C)}AMB(k?1)). The ambient HOA component ({tilde over (C)}AMB(k?1)) comprises, in a layered mode, first HOA coefficient sequences of the input HOA representation (cn(k?1)) in lower positions and second HOA coefficient sequences (cAMB,n(k?1)) in remaining higher positions. The second HOA coefficient sequences are part of an HOA representation of a residual between the input HOA representation and the HOA representation of the predominant sound signals.
