Multi-channel signal encoding and decoding

TL;DR: In this paper, an audio encoder dynamically selects between joint and independent coding of a multi-channel audio signal via an open-loop decision based upon energy separation between the coding channels, and the disparity between excitation patterns of the separate input channels.

TL;DR: In this paper, a port adapter for connecting zero or more network interfaces to a host system having a SPI-4 bus is described, which consists of a network interface, a control bus coupled to the host system for controlling and monitoring the port adapter, and interface logic that interfaces the SPI4 bus and the control bus to the network interfaces.

TL;DR: In this article, the authors describe architectures and techniques that improve the efficiency of multi-channel audio coding and decoding, which can be used in combination or independently, and describe various techniques and tools.

TL;DR: In this article, the authors proposed a joint coding scheme that considers the statistical properties of the source signals, the properties of mixing techniques, and spatial hearing to determine the perceptually important spatial cues of the final mixed audio channels.

TL;DR: In this article, a wideband speech signal (8 kHz) of high quantity is reconstructed from a narrowband speech signals (300 Hz to 3.4 kHz) by LPC-analyzing to obtain spectrum information parameters.

TL;DR: A subband audio coder employs perfect/nonperfect reconstruction filters, predictive/non-predictive subband encoding, transient analysis, and psycho-acoustic/minimum mean square error (mmse) bit allocation over time, frequency and the multiple audio channels to encode/decode a data stream to generate high fidelity reconstructed audio as mentioned in this paper.

TL;DR: The general structure of this class of coders is reviewed, and the particulars of its members are discussed and the contributions of the various coder parameters to the performance of the coder are examined.

TL;DR: The audio coding standard developed by the Moving Pictures Expert Group within the International Organization for standardization (ISO/MPEG) is covered in some detail, since it will be used in many application areas, including digital storage, transmission, and broadcasting of audio-only signals and audiovisual applications such as videotelephony, videoconferencing, and TV broadcasting.
