Overview
Ordering number : EN5663 CMOS IC LC83026E Digital Signal Processor for Karaoke Systems 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.
• Features • Application features — Pitch shift The LC83026E supports pitch shifting of ±15 quarter tone steps, or ±1 octave in scale tone units as specified by command data.
This pitch shifting can be applied either to the music track or to the microphone input.
It is also possible to set up pitch shifting of ±1 octave in arbitrary steps by...
