The audio coding method and apparatus reduce the number of calculations of an audio coding algorithm to improve efficiency of an audio coding process. Specifically, the ... 10/19/06 - 20060235678 - Apparatus and method of encoding audio data and apparatus and method of decoding encoded audio data An apparatus and method encode audio data, and an apparatus and method decode encoded audio data. An audio data encoding apparatus includes: a scalable encoding unit dividing audio data into a plurality of layers, representing the audio data in predetermined numbers of bits in each of the plurality of layers, ... 09/14/06 - 20060206314 - Adaptive variable bit rate audio compression encoding An adaptive variable bit rate audio encoder and method that examines audio level information and detects various information in the audio data in a psychoacoustic model to create a quantization value and assign a mode tag to a single frame of audio. A bit rate is assigned according to one ... 08/31/06 - 20060195314 - Optimized fidelity and reduced signaling in multi-channel audio encoding The invention provides an efficient technique for encoding a multi-channel audio signal. The invention relies on the principle of encoding (S1) a signal representation of one or more of the multiple channels in a first encoding process, and encoding another signal representation of one or more channels in a second, ... 06/08/06 - 20060122823 - Method and apparatus for processing asynchronous audio stream A method and an apparatus for processing an asynchronous audio stream are provided. A corrupted PES packet is detected from an asynchronous audio PES stream, and the ADTS frames of the corrupted PES packet are detected and replaced with predetermined substitute ADTS frames. Thus, an AAC stream is restored from ... 05/04/06 - 20060095253 - Device and method for embedding binary payload in a carrier signal For embedding binary payload in a carrier signal, which, for example, is an audio signal, a sequence of time-discrete values of the carrier signal is converted to the frequency domain by means of an integer transform algorithm to obtain binary spectral representation values. Bits of the binary spectral representation values ... 03/30/06 - 20060069548 - Audio output apparatus and audio and video output apparatus The present invention relates to an audio output apparatus and an audio and video output apparatus which enable a user to recognize output speech even when ambient noise increases or when a loud irregular noise occurs. The audio and video output apparatus includes an audio unit for supplying sound including ... 01/05/06 - 20060004566 - Low-bitrate encoding/decoding method and system A low-bitrate encoding system includes: a time-frequency transform unit transforming an input time-domain audio signal into a frequency-domain audio signal; a frequency component processor unit decimating frequency components in the frequency-domain audio signal; a psychoacoustic model unit modeling the received time-domain audio signal on the basis of human auditory characteristics, ... 01/05/06 - 20060004565 - Audio signal encoding device and storage medium for storing encoding program An encoding device which encodes audio signals comprises a spectrum power calculation unit for calculating the power of each spectrum obtained by analyzing the frequency of an input audio signal, a tonality parameter calculation unit for calculating a tonality parameter indicating the pure tone level of the input audio signal ... 12/15/05 - 20050278165 - Method and system for increasing audio perceptual tone alerts A method, system and computer readable medium for increasing the audio perceptual loudness includes shifting at least one frequency of a first audio signal to create a second audio signal so as to increase the audio perceptual loudness. The power level of the second audio signal is not more than ... 11/24/05 - 20050261892 - Audio encoding with different coding models A method for supporting an encoding of an audio signal is shown, wherein at least a first and a second coder mode are available for encoding a section of the audio signal. The first coder mode enables a coding based on two different coding models. A selection of a coding ... 07/28/05 - 20050165603 - Method and device for frequency-selective pitch enhancement of synthesized speech In a method and device for post-processing a decoded sound signal in view of enhancing a perceived quality of this decoded sound signal, the decoded sound signal is divided into a plurality of frequency sub-band signals, and post-processing is applied to at least one of the frequency sub-band signal. After ... 06/30/05 - 20050143973 - Digital signal sub-band separating/combining apparatus achieving band-separation and band-combining filtering processing with reduced amount of group delay An apparatus having a band-separating filter bank for separating a digital signal into a plurality of sub-band signals, to be processed or transmitted, and a band-combining filter bank for subsequently combining the resultant sub-band signals into a single digital signal, wherein each of the band-separating filter bank and band-combining filter ... 06/09/05 - 20050125222 - Responding to recipient rated wirelessly broadcast electronic works A method, system, and program for responding to recipient ratings of wirelessly broadcast electronic works are provided. A secondary player receives a wireless broadcast of an electronic work from a primary player. Next, responsive to a playback of the electronic work from the secondary player, the secondary player requires a ... 06/09/05 - 20050125221 - Controlling access to wirelessly broadcast electronic works during playback A method, system, and program for controlling access to wirelessly broadcast electronic works during playback are provided. A wireless broadcast of an electronic work with digital rights rules is received from a primary player at a secondary player. Synchronous play of the electronic work at the secondary player may be ... 06/02/05 - 20050119877 - Method and system for aligning natural and synthetic video to speech synthesis According to MPEG-4's TTS architecture, facial animation can be driven by two streams simultaneously—text, and Facial Animation Parameters. In this architecture, text input is sent to a Text-To-Speech converter at a decoder that drives the mouth shapes of the face. Facial Animation Parameters are sent from an encoder to the ... ### FreshPatents.com Support |
