Introduction to Digital Audio Coding and Standards

Introduction to AVS Audio Lossless Coding/Decoding Standard

1. Introduction Recently, massive storage technology, especially Blu-ray Disk, has become more sophisticated. The demand for high quality digital audio can now be met. Audio lossless coding compresses digital audio data without any loss in quality due to a perfect reconstruction of the original signal.

MPEG Digital Audio Coding Standards

A Review of Algorithms for Perceptual Coding of Digital Audio Signals

During the last decade, CD-quality digital audio has essentially replaced analog audio. During this same period, new digital audio applications have emerged for network, wireless, and multimedia computing systems which face such constraints as reduced channel bandwidth, limited storage capacity, and low cost. These new applications have created a demand for high-quality digital audio delivery a...

Algorithm and VLSI Architecture Design for MPEG-Like High Definition Video Coding‐AVS Video Coding from Standard Specification to VLSI Implementation

In multimedia system, there are several video coding standards such as MPEG-1/2/4 [1]-[3], H.264/AVC [4], VC-1 [5], they are the source coding technology basis for digital multimedia applications. Despite of the emerging HEVC standard [6], H.264/AVC is the most mature video coding standard [4] [9]. China Audio and Video Coding Standard (AVS) is a new standard targeted for video and audio coding...

Standards for audio and music representation

adapted from Noll (2000) Audio compression or audio coding algorithms are used to obtain compact digital representations of high-fidelity (wideband) audio signals for the purpose of efficient transmission or storage. The central objective in audio coding is to represent the signal with a minimum number of bits while achieving transparent signal reproduction, i.e., generating output audio that c...
