Patent
Quality improvement techniques in an audio encoder
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.
Patent
Multi-channel audio encoding and decoding
Naveen Thumpudi,Wei-ge Chen +1 more
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.
Patent
Bitstream syntax for multi-process audio decoding
TL;DR: In this article, an audio decoder provides a combination of decoding components including components implementing base band decoding, spectral peak decoding, frequency extension decoding and channel extension decoding techniques, and a bitstream syntax scheme to permit the various decoding components to extract the appropriate parameters for their respective decoding technique.
Patent
Adaptive window-size selection in transform coding
TL;DR: In this paper, a transform coder adaptively configures window sizes for transform coding in a two-pass process to maximize coding efficiency, while achieving necessary time resolution to avoid pre-echo.
Patent
Quality and rate control strategy for digital audio
TL;DR: In this paper, an encoder regulates quantization using quality, minimum bit count, and maximum bit count parameters, and the encoder corrects model bias by adjusting a control parameter value in view of current buffer fullness.
