One discriminant is based on the rate (relative to the sample rate) at which ... 10/19/06 - 20060235680 - Apparatus, method and computer program product for processing acoustical-signal An acoustical-signal processing apparatus includes a feature extracting unit that extracts feature data common to each channel signal which forms a multichannel acoustical signal, based on a composite similarity obtained by combining similarities calculated from each channel signal; and a time-base companding unit that executes time compression and time expansion ... 10/19/06 - 20060235679 - Adaptive grouping of parameters for enhanced coding efficiency The present invention is based on the finding that parameters including a first set of parameters of a representation of a first portion of an original signal and including a second set of parameters of a representation of a second portion of the original signal can be efficiently encoded, when ... 10/12/06 - 20060229868 - Method for estimating resonance frequencies The present invention is related to a method for estimating from an input signal the resonance frequencies of a system modelled as a source and a filter, comprising the steps of—determining the Z-transform of the input signal,—calculating the differential-phase spectrum of the Z-transformed input signal, whereby the Z-transform is evaluated ... 06/22/06 - 20060136198 - Method and apparatus for low bit rate encoding and decoding An apparatus and method of low bit rate encoding and reproducing. The method includes transforming input audio signals in a time domain into spectral signals in a frequency domain, extracting important-spectrum components from the spectral signals in the frequency domain, and quantizing the important-spectrum components, extracting residual-spectrum components other than ... 03/30/06 - 20060069549 - Updating of a buried data channel The present invention relates to methods, devices, a media signal as well as a recorded medium relating to a media signal having audio samples including a buried data channel (30, 32, 34, 36). The buried data channel (30, 32, 34, 36) provided in the audio samples of a media signal ... 02/16/06 - 20060036432 - Apparatus and method applying adaptive spectral whitening in a high-frequency reconstruction coding system The present invention proposes a new method and a new apparatus for enhancement of audio source coding systems utilising high frequency reconstruction (HFR). It utilises adaptive filtering to reduce artifacts due to different tonal characteristics in different frequency ranges of an audio signal upon which HFR is performed. The present ... 02/16/06 - 20060036431 - Audio coding Coding of an audio signal represented by a respective set of sampled signal values for each of a plurality of sequential segments is disclosed. The sampled signal values are analysed (40) to determine one or more sinusoidal components for each of the plurality of sequential segments. The sinusoidal components are ... 12/01/05 - 20050267740 - Signal processing apparatus and method, recording medium, and program For accurate scene-change detection, the amplitudes of sub-band signals subjected to the spectral decomposition are detected, and the detected amplitudes are smoothed and sampled during smoothing. Then, the amount of spectral change is determined based on the smoothed sub-band amplitude and the smoothed sub-band amplitude which is one sampled amplitude ... 09/08/05 - 20050197832 - Modulation depth enhancement for tone perception A sound processing process is disclosed, with particular application to auditory prostheses. After input sound signals are processed into channels, an algorithm is applied to selectively increase the modulation depth of the envelope signals. ... 07/07/05 - 20050149320 - Method for generating noise references for generalized sidelobe canceling This invention describes a method for generating noise references for adaptive interference cancellation filters for applications in generalized sidelobe canceling systems. More specifically the present invention relates to a multi-microphone beamforming system similar to a generalized sidelobe canceller (GSC) structure, but the difference with the GSC is that the present ... 06/02/05 - 20050119880 - Method and apparatus for subsampling phase spectrum information Method and apparatus for subsampling phase spectrum information by analyzing and reconstructing a prototype of a frame. The prototype is analyzed by correlating phase parameters generated from the prototype with phase parameters generated from a reference prototype in multiple frequency bands. The prototype is reconstructed using linear phase shift values ... ### FreshPatents.com Support |
