Audio Coding - an overview | ScienceDirect Topics

    https://www.sciencedirect.com/topics/computer-science/audio-coding
    AUDIO AND WIDEBAND SPEECH COMPRESSION. Audio coding usually refers to the compression of high-fidelity audio signals, i.e., with 15- or 20-kHz bandwidth for consumer hi-fi, professional audio including motion picture and HDTV audio, and various multimedia systems. Sometimes the term audio coding is also used to refer to wideband speech coding, the compression of 7-kHz …

    CS-ACELP (8000 bps) This is speech compressed using the Conjugate-Structured Algebraic Code Excited Linear Prediction (CS-ACELP) scheme. The bit rate is 1 bit/sample (compression ratio of 8:1). CELP (4800 bps) This is speech compressed using the Code Excited Linear Prediction (CELP) scheme. The bit rate is 0.6 bits/sample (compression ratio of 13.3:1).

    compression algorithms that are implemented as audio codec. Lossless Audio Compression removes redundant data, resulting signal is same as original – perfect reconstruction. Lossy Audio Encoding removes irrelevant data, resulting signal is similar to original. Information redundancy is reduced in both forms of compression with the use of methods like coding, pattern

Opus (audio format) - Wikipedia

    https://en.wikipedia.org/wiki/Opus_(audio_format)
    Opus is a lossy audio coding format developed by the Xiph.Org Foundation and standardized by the Internet Engineering Task Force, designed to efficiently code speech and general audio in a single format, while remaining low-latency enough for real-time interactive communication and low-complexity enough for low-end embedded processors. Opus replaces both Vorbis and …
