Question

Quizplus · Accepted Answer

Adaptive differential pulse code modulation (ADPCM) is a digital encoding technique used in telecommunications and voice applications over lower-speed digital circuits. It is especially useful for real-time voice communication where low latency and low bandwidth are important. ADPCM compresses the digital voice signal to reduce the number of bits that need to be transmitted over the circuit. This results in higher-quality voice transmission and fewer communication glitches.
