Sound quality is typically an assessment of the accuracy, fidelity, or intelligibility of audio output from an electronic device. 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 ...
When performing lossy audio encoding, such as creating an MP3 data stream, there is a trade-off between the amount of data generated and the sound quality of the results. The person generating an MP3 selects a bit rate, which specifies how many kilobits per second of audio is desired. The higher the bit rate, the larger the MP3 data stream will ...
Audiophile. An audiophile (from Latin: audīre, lit. 'to hear' + Greek: φίλος, romanized : philos, lit. 'loving') is a person who is enthusiastic about high-fidelity sound reproduction. [1] An audiophile seeks to reproduce recorded music to achieve high sound quality, typically in a quiet listening space and in a room with good acoustics.
For example, MP3 and AAC dominate the personal audio market in terms of market share, though many other formats are comparably well suited to fill this role from a purely technical standpoint. First public release date is first of either specification publishing or source releasing, or in the case of closed-specification, closed-source codecs ...
1 / 2. Billy Steele/Engadget. We've heard this pitch before from Amazon. Last year, the company debuted the $150 Echo Plus in an attempt to improve audio quality in its smart speaker line. It also ...
High fidelity. Hi-fi speakers are a key component of quality audio reproduction. High fidelity (often shortened to Hi-Fi or HiFi) is the high-quality reproduction of sound. [1] It is popular with audiophiles and home audio enthusiasts. Ideally, high-fidelity equipment has inaudible noise and distortion, and a flat (neutral, uncolored) frequency ...
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 ).
Audio system measurements are a means of quantifying system performance. These measurements are made for several purposes. Designers take measurements so that they can specify the performance of a piece of equipment. Maintenance engineers make them to ensure equipment is still working to specification, or to ensure that the cumulative defects ...
