    Abstract: A method and corresponding system for generating harmonics from an input signal having an input frequency uses a harmonics generator having an associated gain controller generating adjustable gain control factors, controlling the amplitude of harmonic components. The method includes generating a series of harmonic components in a process including adjustment of relative balances between at least three harmonic components of different orders, the balances being independently adjustable by controlling at least two gain control factors. Each gain control factor is adjusted based on a frequency dependent measure of the input signal or signal derived therefrom, of the frequency dependent measure of the input signal and/or derived signal unique for the corresponding gain control factor. An output signal is created including the harmonic components according to the balances as controlled by the at least two gain control factors, wherein the balances between the harmonic components depend on the input frequency.

  • Patent number: 11335356
    Abstract: A local extremum calculator detects a local maximum sample and a local minimum sample of a digital audio signal. A number-of-sample detector detects a sample interval between the local maximum sample and the local minimum sample. A difference value calculator calculates difference values between adjacent samples. A correction value calculator calculates a first correction value by multiplying the difference value between the local maximum sample and a first adjacent sample by a coefficient and calculates a second correction value by multiplying the difference value between the local minimum sample and a second adjacent sample by the coefficient. When a periodic signal detector detects that the digital audio signal is a single sine wave, an adder/subtractor does not add the first correction value to the first adjacent sample, and does not subtract the second correction value from the second adjacent sample.

    Abstract: In some aspects, control circuitry receives and stores a user-specified time duration to associate with a skip-forward command. When the user later issues a skip-forward command to advance playback of a media asset to a desired location, the control circuitry retrieves the stored time duration, and determines an expected overshoot value associated with the skip-forward command. The control circuitry then compensates for the expected overshoot by calculating a new location in the media asset based on both the retrieved time duration and expected overshoot value. Upon advancing to the new location, the media asset is played back in a fast-forward mode, e.g., at a speed higher than normal speed.

  • Patent number: 10681486
    Abstract: A method for obtaining Hi-Res audio transfer information is provided. The method is applicable to the electronic device having a processor. In the method, a first audio signal is captured and converted from the time domain into in the frequency domain to generate a first signal spectrum. Then, a regression analysis is performed on an energy distribution of the first signal spectrum to predict an extended energy distribution according to the first signal spectrum, and head-related parameters are used to compensate for the extended energy distribution to generate an extended signal spectrum. Finally, the first signal spectrum and the extended signal spectrum are combined into a second signal spectrum which is converted from the frequency domain into the time domain to generate a second audio signal including Hi-Res audio transfer information.

    Abstract: In an apparatus configured to perform signal processing on audio data of a first sampling rate, methods disclosed herein comprise receiving audio data of a second sampling rate, the second sampling rate being higher than the first sampling rate. The methods comprise applying filtering to the audio data of the second sampling rate to thereby produce first filtered audio data and second filtered audio data, the first filtered audio data comprising mainly component frequencies which are audible to the human ear, the second filtered audio data comprising mainly components frequencies which are substantially inaudible to the human ear. The methods further comprise applying first signal processing to the first filtered audio data; and applying second signal processing to the second filtered audio data, the second signal processing having a lower computational complexity than the first signal processing. Corresponding apparatus and computer readable media are also disclosed herein.

    Abstract: The present technology relates to an audio processing apparatus, a method, and a program that aim at enabling a sound to be reproduced more efficiently. A head-related transfer function synthesis section previously holds a matrix of a diagonalized head-related transfer function. The head-related transfer function synthesis section synthesizes an input signal in an annular harmonic domain for reproducing a sound and the previously held and diagonalized head-related transfer function. An annular harmonic inverse transformation section performs an annular harmonic inverse transformation on a signal obtained as a result of the synthesis by the head-related transfer function synthesis section on the basis of an annular harmonic function and thereby generates a headphone driving signal in a time frequency domain. The present technology is applicable to an audio processing apparatus.
