Future of Class-D Amplification Technology for IP
Audio Systems

This paper presents near-future perspective of class-
D audio technology and SoC (system-on-chip) solutions
that are needed for IP audio systems and other
home entertainment devices. Music listening environments
are evolving fast. Handheld music players,
Hi-Fi home systems, TV, and mobile phones are now
networked with each other. Wired and wireless network
connectivity, real-time operating system, graphical
user interface, embedded DSP software, multiroom
speakers, and docking capability will be
common features of audio systems. We discuss what
is needed for amplification components of future SoC
solutions and which are missing in the current class-D
amplifier technology.
