Abstract :
For enhancing our existing conference systems product of embedded chairman/delegate units, a low cost embedded chairman/delegate units design is proposed in this paper, which is capable of digital audio processing for digital conference system. In addition, the functionality of an automatic gain control (AGC), a dynamic range compression (DRC), and a 2.5W embedded class-D speaker amplifier is also supported in this design.
