Filtering and down sampling means are firstly applied to reduce data of samples. The selected data samples are firstly compressed by means of ADPCM. The error between the original and the ADPCM coded data stream are calculated and compared ... 03/30/06 - 20060069550 - Continuous backup audio A digital audio encoder receives PCM encoded audio information and encodes it with first and second types of digital audio coding, the encoded audio information having self-contained data units, wherein corresponding pairs of self-contained data units encoded with the first type and second type of digital audio coding represent the ... 03/23/06 - 20060064299 - Device and method for analyzing an information signal For analyzing an information signal consisting of a superposition of partial signals, wherein a partial signal originates from an individual source, the information signal is first decomposed into several component signals. Then one or more features are calculated for each component signal, wherein the feature(s) is/are defined so that it/they ... 12/08/05 - 20050273322 - Audio signal encoding and decoding apparatus An audio signal encoding and decoding apparatus capable of transmitting an audio signal or an audio signal together with a sound-field-effect-processed audio signal are provided. The audio signal encoding apparatus includes a core encoder to encode an input audio signal according to an audio signal encoding standard, a core decoder ... 10/06/05 - 20050222841 - System and method for providing interactive audio in a multi-channel audio environment DTS Interactive provides low cost fully interactive immersive digital surround sound environment suitable for 3D gaming and other high fidelity audio applications, which can be configured to maintain compatibility with the existing infrastructure of Digital Surround Sound decoders. The component audio is stored and mixed in a compressed and simplified ... ### FreshPatents.com Support |
