Sanyo Electric LC83026E

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.

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 setting coefficient values. — Microphone echo The LC83026E can apply echo processing to the input signal from the microphone A/D converter. The echo coefficients, including amount of echo and delay time, can be set. — Voice muting The LC83026E provides attenuation of monaural components in the music signal. This allows CDs that include vocals to be used for karaoke. The voice muting function is turned on or off by command data transferred over the serial interface. — Simple surround The LC83026E implements a simple surround simulation function by adding delay components to the music signal. The LC83026E includes six sets of simple surround coefficients as preset data, and these can be selected and switched using command data transferred over the serial interface.
