Sixth International Conference on Parallel and Distributed Computing Applications and Technologies (PDCAT'05), 2005
AVS Audio Coding Standard is the first standard for Hi-Fi audio in China. The framework of AVS Audio was introduced. Many key technologies are described in details, including long/short window switch decision based on energy and unpredictability, integer MDCT for lossless time-frequency transform, square polar stereo coding, and context-dependent ...

Flexcode - flexible audio coding
2010 IEEE International Conference on Acoustics, Speech and Signal Processing, 2010Modern networks are highly variable and, as a result, source coders are commonly used under conditions that they were not designed for. We address this problem with a source-coding philosophy that aims at the instantaneous re-optimization of a source coder to match a wide range of constraints on rate or quality and a wide range of packet-loss rates. We

Quantization and psychoacoustic model in audio coding in advanced audio coding
SPIE Proceedings, 2011This paper presents complete optimized architecture of Advanced Audio Coder quantization with Huffman coding. After that psychoacoustic model theory is presented and few algorithms described: standard Two Loop Search, its modifications, Genetic, Just Noticeable Level Difference, Trellis-Based and its modification: Cascaded Trellis-Based Algorithm.

A multi-channel audio encoder (10) for encoding a multi-channel audio signal (101), e.g. a 5.1 channel audio signal, into a spatial down-mix (102), e.g. a stereo signal, and associated parameters (104, 105). The encoder (10) comprises first and second units (110, 120).

Typical appearance models of speech and audio signals can be determined from physical models of the human vocal tract and of musical instruments, respectively. These are often expressed as filters excited by a source (source-filter model). The importance of periodic components is related to the harmonic properties of many audio sources; harmonic ...

This chapter presents DRA (Dynamic Resolution Adaptation) audio coding standard [97] as an example to illustrate how to integrate the technologies described in this book to create a practical audio coding algorithm. DRA algorithm has been approved by the Blu-ray Disc Association as part of its BD-ROM 2.3 specification [99] and by Chinese government as ...

The Moving Pictures Expert Group (MPEG) within the International Organization of Standardization (ISO) has developed a series of audio-visual standards known as MFEG-1 and MPEG-2. These audio-coding standards are the first international standards in the field of high-quality digital audio compression.
