Overview

The LC83026E provides the audio signal processing required in karaoke systems, including pitch shift, microphone echo, voice muting, and simple surround simulation. It is a special-purpose DSP that implements karaoke processing with the addition of a single external 256-Kb DRAM. The LC83026E includes on-chip A/D and D/A converters and supports both digital and analog inputs and outputs. Its functions and characteristics can be modified to match the needs of the end product by sending coefficient data from the microcontroller over a serial interface.
