The average values of a predetermined amount of audio samples within a pack ... 09/28/06 - 20060217973 - Adaptive voice mode extension for a voice activity detector There is provided a voice activity detection method for indicating an active voice mode and an inactive voice mode. The method comprises receiving a first portion of an input signal; determining that the first portion of the input signal includes an active voice signal; indicating the active voice mode in ... 09/21/06 - 20060212289 - Apparatus and method for converting voice packet rate Provided is a voice packet rate converting method and apparatus. The rate of at least one first element of an input voice packet compressed at a first rate is converted to a second rate at a PCM level, and the rate of a second element of the input voice packet ... 09/14/06 - 20060206318 - Method and apparatus for phase matching frames in vocoders In one embodiment, the present invention comprises a vocoder having at least one input and at least one output, an encoder comprising a filter having at least one input operably connected to the input of the vocoder and at least one output, a decoder comprising a synthesizer having at least ... 08/24/06 - 20060190246 - Transcoding method for switching between selectable mode voice encoder and an enhanced variable rate codec An apparatus comprising an encoder circuit and a transcoder circuit. The encoder circuit may be configured to generate a bitstream comprising a series of packets in response to a speech input signal. The transcoder circuit may be configured to generate an intermediate bitstream in response to the bitstream. The transcoder ... 05/25/06 - 20060111899 - System and method for error reconstruction of streaming audio information A method includes receiving a sequence of frames containing audio information and determining that a frame is missing in the sequence of frames. The method also includes comparing the frame that precedes the missing frame to the received frames to identify a selected frame. The method further includes identifying a ... 05/11/06 - 20060100865 - Methods and apparatus for efficient vocoder implementations Techniques for implementing vocoders in parallel digital signal processors are described. A preferred approach is implemented in conjunction with the BOPS® Manifold Array (ManArray™) processing architecture so that in an array of N parallel processing elements, N channels of voice communication are processed in parallel. Techniques for forcing vocoder processing ... 03/09/06 - 20060053004 - Fast codec with high compression ratio and minimum required resources This invention provides a novel single-pass and multi-pass synchronized encoder and decoder, performing order(s) of magnitude faster data compression and decompression, at any compression ratio with the higher or the same perceived and measured decompressed image quality in comparison with the best state-of-the-art compression methods, using order(s) of magnitude less ... 12/22/05 - 20050283362 - Speech coder/decoder A coding parameter control circuit 31 computes a frame length from a bit rate and coding delay, and provides the computed frame length data to a CELP coding circuit 32. Based on the computed frame length, the coding parameter control circuit 32 selects control parameters from a table, in which ... 12/15/05 - 20050278168 - Systems and methods for parsing flexible audio codec topologies Systems and methods for parsing flexible audio codec topologies are described. In one aspect, codec topology information is obtained from an audio codec. The codec topology information includes a list of processing node connections and configuration default data for respective processing nodes associated with the audio codec. The codec topology ... 12/01/05 - 20050267743 - Method for codec mode adaptation of adaptive multi-rate codec regarding speech quality Method of codec mode adaptation of a speech codec in dependency of the prevailing channel condition for transmission of speech frames in a telecommunication system comprising the steps of determining a bit error rate (BER) from a estimated carrier to interferer ratio (C/I) per speech burst, generating a frame BER ... 11/24/05 - 20050261899 - Methods of improving capacity for voice users in a communication network In a method for improving capacity for voice users in a communication network and/or a method of avoiding channelization code starvation in the downlink when establishing a voice call with one or more users in the wireless network, two sets of channelization codes may be defined, each adapted for use ... ### FreshPatents.com Support |
