Perceptual Evaluation of Audio Quality

Index Perceptual Evaluation of Audio Quality

Perceptual Evaluation of Audio Quality (PEAQ) is a standardized algorithm for objectively measuring perceived audio quality, developed in 1994–1998 by a joint venture of experts within Task Group 6Q of the International Telecommunication Union's Radiocommunication Sector (ITU-R). [1]

Auditory masking

In audio signal processing, auditory masking occurs when the perception of one sound is affected by the presence of another sound.

Auditory system

The auditory system is the sensory system for the sense of hearing.

Bitstream

A bitstream (or bit stream), also known as binary sequence, is a sequence of bits.

Centre commun d'études de télévision et télécommunications

CCETT or Centre commun d'études de télévision et télécommunications (Centre for the Study of Television broadcasting and Telecommunication or Common Study Center of Telediffusion and Telecommunication) was a research centre created in Rennes (France) in 1972 jointly by the Office de Radiodiffusion Télévision Française (ORTF) (later Télédiffusion de France) and Centre National d'Etudes des Telecommunications (CNET) (Direction Générale des Télécommunications, part of the French Ministry of Posts and Telecommunications) for development of new techniques for processing, transmission and distribution of audiovisual signals.

Codec

A codec is a device or computer program that encodes or decodes a data stream or signal.

See Perceptual Evaluation of Audio Quality and Codec

Data compression

In information theory, data compression, source coding, or bit-rate reduction is the process of encoding information using fewer bits than the original representation. Perceptual Evaluation of Audio Quality and data compression are Digital audio.

Deutsche Telekom

Deutsche Telekom AG (often just Telekom, DTAG or DT; stylised as ·T·) is a German telecommunications company headquartered in Bonn and is the largest telecommunications provider in Europe by revenue.

Discrete Fourier transform

In mathematics, the discrete Fourier transform (DFT) converts a finite sequence of equally-spaced samples of a function into a same-length sequence of equally-spaced samples of the discrete-time Fourier transform (DTFT), which is a complex-valued function of frequency.

Hearing-Aid Speech Quality Index

Hearing-Aid Speech Quality Index (HASQI) is a measure of audio quality originally designed for the evaluation of speech quality for those with a hearing aid,. Perceptual Evaluation of Audio Quality and hearing-Aid Speech Quality Index are audio codecs and Digital audio.

Perceptual Evaluation of Speech Quality

Perceptual Evaluation of Speech Quality (PESQ) is a family of standards comprising a test methodology for automated assessment of the speech quality as experienced by a user of a telephony system.

Perceptual Evaluation of Video Quality

Perceptual Evaluation of Video Quality (PEVQ) is an end-to-end (E2E) measurement algorithm to score the picture quality of a video presentation by means of a 5-point mean opinion score (MOS).

Psychoacoustics

Psychoacoustics is the branch of psychophysics involving the scientific study of sound perception and audiology—how the human auditory system perceives various sounds.

Reasonable and non-discriminatory licensing

Reasonable and non-discriminatory (RAND) terms, also known as fair, reasonable, and non-discriminatory (FRAND) terms, denote a voluntary licensing commitment that standards organizations often request from the owner of an intellectual property right (usually a patent) that is, or may become, essential to practice a technical standard.

Sound quality

Sound quality is typically an assessment of the accuracy, fidelity, or intelligibility of audio output from an electronic device.

See Perceptual Evaluation of Audio Quality and Sound quality

Spectral density

In signal processing, the power spectrum S_(f) of a continuous time signal x(t) describes the distribution of power into frequency components f composing that signal.
