Why did Telos select ISO/MPEG Layer III perceptual audio coding?
Layer III is the most sophisticated method for the coding of digital audio. When combined with ISDN, our Layer III codec (coder/decoder) makes it possible to transmit broadcast-quality audio with the convenience, global availability, and low cost of the dial-up telephone network. Can you assure me that Layer III sounds good? You don’t have to take our word for it. The sound quality of Layer III has been demonstrated in tests performed by the International Telecommunications Union (ITU). To develop recommendations for the use of low bit-rate codecs for digital sound broadcasting applications, an international large-scale test was carried out over a period of almost three years. Nearly all available worldwide low bit-rate codecs were evaluated. Layer III was the only codec that provided acceptable sound quality for mono coding at 60kbps. The final report of ITU Radiocommunication Task Group 10/2 clearly recommends Layer III for ISDN bit rates, and the daily experience of Layer III users
