PESQ is a full-reference algorithm and analyzes the speech signal sample-by-sample after a temporal alignment of corresponding excerpts of reference and test signal. PESQ can be applied to provide an end-to-end (E2E) quality assessment for a network, or characterize individual network components. PESQ results principally model mean opinion ...
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 ...
Sound Check is a proprietary Apple Inc. technology similar in function to ReplayGain. It is available in iTunes and on the iPod. [5] Standard measurement algorithms for broadcast loudness monitoring applications have recently been developed by the International Telecommunication Union (ITU-R BS.1770) and the European Broadcasting Union .

The audio is further processed by the Neural Audio processors on the way to broadcast. In the past, the Sirius XM Pops channel, which aired classical music, was broadcast in 5.1 surround sound . The technology, titled XM HD Surround , is the result of a partnership between XM and Neural Audio Corporation which provides content with six discrete ...
Perceptual Objective Listening Quality Analysis ( POLQA) was the working title of an ITU-T standard that covers a model to predict speech quality by means of analyzing digital speech signals. [ 1] The model was standardized as Recommendation ITU-T P.863 (Perceptual objective listening quality assessment) in 2011.
Wave Radio. Wave Radio/CD. The "Wave Radio" (which has since become known as "Wave Radio I") was an AM/FM clock radio that was introduced in 1993. It was smaller than the Acoustic Wave Music System and used two 2.5-inch speakers. [ 3] A "Wave Radio/CD" model was introduced in 1998 and was essentially a Wave Radio I with a CD player.
Signal strength and readability report. A signal strength and readability report is a standardized format for reporting the strength of the radio signal and the readability (quality) of the radiotelephone (voice) or radiotelegraph (Morse code) signal transmitted by another station as received at the reporting station's location and by their ...
t. e. The fifth generation iPod Touch (stylized and marketed as the iPod touch, and colloquially known as the iPod Touch 5G, iPod Touch 5, or iPod 5) is a mobile device designed and marketed by Apple Inc. with a touchscreen-based user interface. The successor to the 4th-generation iPod Touch, it was unveiled at Apple's media event alongside the ...
