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 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. User-original
surround effects can be implemented by setting
coefficients, but the algorithm is fixed.
— Versatile input mixing
The LC83026E supports hybrid mixing of digital
music inputs and analog music inputs for both the
left and right channels to support the processing of a
wide range of disks.
