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 . It was originally released as ITU-R Recommendation BS.1387 in 1998 and ...
An audio analyzer is a test and measurement instrument used to objectively quantify the audio performance of electronic and electro-acoustical devices. Audio quality metrics cover a wide variety of parameters, including level, gain, noise, harmonic and intermodulation distortion, frequency response, relative phase of signals, interchannel crosstalk, and more.
A second, different Sound Recorder was introduced in Windows 8.1, thus Windows 8.1 has two distinct apps called Sound Recorder. This second app was a Windows Store app and adhered to the design tenets of the Metro design language. [2] Leaked images of a preview version Windows 10 Mobile showed this app too. [3] When Windows 10 released, however ...
Quality can be measured objectively, such as when tools are used to gauge the accuracy with which the device reproduces an original sound; or it can be measured subjectively, such as when human listeners respond to the sound or gauge its perceived similarity to another sound. [1] The sound quality of a reproduction or recording depends on a ...
This version added real-time effects, VST3 support and a streamlined interface. A cloud audio sharing integration with audio.com is added. [61] 3.1 October 28, 2021 This version introduced clip handles, smart clips and playback looping. [62] In April 2022, an official Audacity app was added to the Microsoft Store.

A pistonphone is an acoustical calibrator (sound source) that uses a closed coupling volume to generate a precise sound pressure for the calibration of measurement microphones. The principle relies on a piston mechanically driven to move at a specified cyclic rate, pushing on a fixed volume of air to which the microphone under test is coupled.
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. It was standardized as Recommendation ITU-T P.862 [1] in 2001. PESQ is used for objective voice quality testing by phone manufacturers, network ...
A microphone, colloquially called a mic (/ m aɪ k /), [1] or mike, [a] is a transducer that converts sound into an electrical signal. Microphones are used in many applications such as telephones , hearing aids , public address systems for concert halls and public events, motion picture production, live and recorded audio engineering , sound ...
