Sažetak
Compression has become state-of-the-art technology in modern audio communications, both in wide-band and voice-band, thus allowing for a great number of components such as mobile phones, radio and TV satellite networks, Internet audio, digital audio broadcasting below 30 MHz (DRM - Digital Radio Mondiale) and over 30 MHz (DAB - Digital Audio Broadcasting), DVD (Digital Versatile Disc), VoIP (Voice Over Internet Protocol), and many more. Lowering data rates to a minimum is contradictory to clarity and fidelity of sound. In time of "all digital technology", sound quality and the intelligibility of speech have become important again.In this paper we show the results of tests made on various codecs using the PEAQ measurement algorithm according to ITU-R BS.1387.
