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 ...
performing from memory and music-related memory; acts of improvisation and composition; flow experiences; the interpersonal/social aspects of group performance; music performance quality evaluation by an audience or evaluator(s) (e.g. audition or competition), including the influence of musical and non-musical factors; audio engineering [98]
Perceptual audio coding uses psychoacoustics-based algorithms. The psychoacoustic model provides for high quality lossy signal compression by describing which parts of a given digital audio signal can be removed (or aggressively compressed) safely—that is, without significant losses in the (consciously) perceived quality of the sound.
Musical memory refers to the ability to remember music-related information, such as melodic content and other progressions of tones or pitches. The differences found between linguistic memory and musical memory have led researchers to theorize that musical memory is encoded differently from language and may constitute an independent part of the phonological loop.
The model was standardized as Recommendation ITU-T P.863 (Perceptual objective listening quality assessment) in 2011. The second edition of the standard appeared in 2014, and the third, currently in-force edition was adopted in 2018 under the title Perceptual objective listening quality prediction. [2]
Implicit memory centers on the 'how' of music and involves automatic processes such as procedural memory and motor skill learning – in other words skills critical for playing an instrument. Samson and Baird (2009) found that the ability of musicians with Alzheimer's Disease to play an instrument (implicit procedural memory) may be preserved.
Audio therapy is the clinical use of recorded sound, music, or spoken words, or a combination thereof, recorded on a physical medium such as a compact disc (CD), or a digital file, including those formatted as MP3, which patients or participants play on a suitable device, and to which they listen with intent to experience a subsequent beneficial physiological, psychological, or social effect.
