Data Processing: Speech Signal Processing, Linguistics, Language Translation, And Audio Compression/decompression > Speech Signal Processing > For Storage Or Transmission > Noise > Post-transmission Post-transmissionPost-transmission 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.11/23/06 - 20060265216 - Packet loss concealment for block-independent speech codecs A technique for performing frame erasure concealment (FEC) in a speech decoder. One or more non-erased frames of a speech signal are decoded in a block-independent manner. When an erased frame is detected, a short-term predictive filter and a long-term predictive filter are derived based on previously-decoded portions of the ... 09/28/06 - 20060217975 - Audio coding and decoding apparatuses and methods, and recording media storing the methods Audio coding and decoding apparatuses and methods which support fine granularity scalability (FGS) using harmonic information of a high-band audio signal or wideband error audio signal when performing wideband audio coding and decoding, and recording mediums on which the methods are stored. The audio coding method includes detecting harmonics of ... 06/01/06 - 20060116874 - Noise-dependent postfiltering A method of filtering a speech signal is presented. The method involves providing a filter (404) suited for reduction of distortion caused by speech coding, estimating acoustic noise in the speech signal, adapting the filter in response to the estimated acoustic noise to obtain an adapted filter, and applying the ... 04/13/06 - 20060080093 - Decoder An encoded signal is input to an input section. A signal information analyzing section analyzes the signal information of the signal input to the input section and compares the analyzed signal information with EX-encoded signal information stored in a signal information database. Based on the comparison result, an operation mode ... 02/02/06 - 20060025993 - Audio processing An audio system comprises a post-processor (12) arranged to alter successive fragments of a decoded audio signal (14) to provide successive fragments of post-processed audio signal (16). A masking threshold generator (20) provides an estimate of a masking threshold ( ) for successive fragments of post-processed audio signal (16). A ... 11/17/05 - 20050256707 - Digitized audio data reproduction apparatus, and integrated circuit device to output audio signals An audio data reproduction apparatus, integrated circuit device, and computer program product configured to implement a method for reproducing audio data that includes receiving an audio stream, decoding the audio stream, processing the audio stream or a signal produced by the decoding, selecting the signal produced by the decoding or ... ### FreshPatents.com Support |
