High Quality Low-Delay Speech Coding at 12 kb/sFor low-delay speech coders, the research challenge is to obtain higher compression rates while maintaining very high speech quality and meeting stringent low delay requirements. Such coders have applications in telephone networks, mobile radio, and increasingly for in-building wireless telephony.作者: Pamphlet 時(shí)間: 2025-3-22 14:10 作者: 不能妥協(xié) 時(shí)間: 2025-3-22 17:50
