MPEG-4 natural audio coding
MPEG-4 audio represents a new kind of audio coding standard. Unlike its predecessors, MPEG-1 and MPEG-2 high-quality audio coding, and unlike the speech coding standards which have been completed by the ITU-T, it describes not a single or small set of highly e$cient compression schemes but a complete toolbox to do everything from low bit-rate speech coding to high-quality audio coding or music ...
متن کاملCoding of natural audio in MPEG-4
MPEG-4 standardizes natural audio coding at bitrates ranging from 2 kbit/s, suitable for intelligible speech coding, to 64 kbitls per channel, suitable for high-quality audio coding. Within this range, three categories of coding are defined: parametric coding, Code Excited Linear Predictive coding (CELP) and time/frequency (T/F) coding. The unique contribution of MPEG4 audio is that not only do...
متن کاملMPEG-4 Audio Lossless Coding
Lossless coding will become the latest extension of the MPEG-4 audio standard. The lossless audio codec of the Technical University of Berlin was chosen as reference model for MPEG-4 Audio Lossless Coding (ALS). The MPEG-4 ALS encoder is based on linear prediction, which enables high compression even with moderate complexity, while the corresponding decoder is straightforward. The paper describ...
متن کاملLossless Audio Coding for MPEG - 4
Lossless audio compression has been an active research field for the past decade. The main application of the technology is in the archival of digital audio data. With today’s wide spread of broadband networks, the technology has also gradually become popular in online music sharing and distribution. Lossless audio compression can be categorized into two different technical approaches: predicti...
متن کاملMPEG-4 Scalable to Lossless Audio Coding
As the latest extension of MPEG-4 Audio coding, MPEG-4 Lossless Audio Coding includes a scalable audio coding solution (SLS) that integrates the functionalities of lossless audio coding, perceptual audio coding, and fine granular scalable audio coding into a single coder framework while providing backward compatibility to MPEG Advanced Audio Coding (AAC) at the bit-stream level. Despite its abu...
