Data Processing: Speech Signal Processing, Linguistics, Language Translation, And Audio Compression/decompression > Speech Signal Processing > For Storage Or Transmission > Transformation TransformationTransformation patent applications listed are from June 2005 to current and include Date, Patent Application Number, Patent Title, Patent Abstract summary and are linked to the corresponding patent application page.11/09/06 - 20060253277 - Device and method for paramertizable controlling To increase parameterization of control devices which include several inputs and several outputs, all combinations of inputs do not have to be evaluated for determining an output value. The set point value of input states are set to an independent state value such that only those real values and set ... 09/14/06 - 20060206315 - Apparatus and method for separating audio signals The present invention provides an apparatus for separating audio signals that can dissolve the problem of permutation when separating the plurality of mixed signals by independent component analysis. There is provided an audio signal separation apparatus for separating observation signals in a time domain of a mixture of a plurality ... 08/03/06 - 20060173675 - Switching between coding schemes Methods and units are shown for supporting a switching from a first coding scheme to a Modified Discrete Cosine Transform (MDCT) based coding scheme calculating a forward or inverse MDCT with a window (h(n)) of a first type for a respective coding frame, which satisfies constraints of perfect reconstruction. To ... 07/06/06 - 20060149532 - Method and apparatus for enhancing loudness of a speech signal A speech filter (108) enhances the loudness of a speech signal by expanding the formant regions of the speech signal beyond a natural bandwidth of the formant regions. The energy level of the speech signal is maintained so that the filtered speech signal contains the same energy as the pre-filtered ... 06/08/06 - 20060122825 - Method and apparatus for transforming audio signal, method and apparatus for adaptively encoding audio signal, method and apparatus for inversely transforming audio signal, and method and apparatus for adaptively decoding audio signal A method and apparatus for transforming an audio signal, a method and apparatus for adaptively encoding an audio signal, a method and apparatus for inversely transforming an audio signal, and a method and apparatus for adaptively decoding an audio signal. The method of transforming an audio signal includes determining a ... 05/18/06 - 20060106597 - System and method for low bit-rate compression of combined speech and music A system and method of compressing audio signals (110, 116, 130, 136, 140, 146) which simultaneously contain speech (110, 116), music (130, 136, 140, 146) and possibly other audio in such fashion as to reduce the required bandwidth or storage capacity. Audio (110, 116, 130, 136, 140, 146) is transmitted ... 12/08/05 - 20050273319 - Device and method for analyzing an information signal In order to analyze an information signal, a significant short-time spectrum is extracted from the information signal, the means for extracting being configured to extract such short-time spectra which come closer to a specific characteristic than other short-time spectra of the information signal. The short-time spectra extracted are then decomposed ... 09/15/05 - 20050203731 - Lossless audio coding/decoding method and apparatus A lossless audio coding and/or decoding method and apparatus are provided. The coding method includes: mapping the audio signal in the frequency domain having an integer value into a bit-plane signal with respect to the frequency; obtaining a most significant bit and a Golomb parameter for each bit-plane; selecting a ... 09/15/05 - 20050203730 - Weight function generating method, reference signal generating method, transmission signal generating apparatus, signal processing apparatus and antenna A rectangular wave for determining a range of a weight function is transformed to frequency domain by an FFT or the like, and after being multiplied by a window function (BlackmanHarris window function, for example) generated on a frequency axis by a multiplier, the frequency domain is transformed again to ... 08/25/05 - 20050187760 - Audio coding Coding (1) of an audio signal is provided including estimating (110) a position of a transient signal component in the audio signal, matching (111,112) a shape function on the transient signal component in case the transient signal component is gradually declining after an initial increase, which shape function has a ... 08/04/05 - 20050171767 - Model adaptive apparatus and model adaptive method, recording medium, and pattern recognition apparatus In order to improve recognition performance, a no-speech sound model correction section performs an adaptation of a no-speech sound model which is a sound model representing a no-speech state on the basis of input data observed in an interval immediately before a speech recognition interval for the object of speech ... 07/21/05 - 20050159940 - Method and system for reduction of quantization-induced block-discontinuities and general purpose audio codec Compressing the digitized time-domain continuous input signal typically includes formatting the input signal into a plurality of time-domain blocks having boundaries, forming an overlapping time-domain block by prepending a fraction of a previous time-domain block to a current time-domain block, transforming each overlapping time-domain block to a transform domain block ... ### FreshPatents.com Support |
