TC9444F
Single-Chip karaoke IC II
The TC9444F is a karaoke chip for such applications as
equipment for CD/LD players, mini component stereo sets,
radio-cassette players, and VTRs.
With its internal AD/DA converter system, the TC9444F can
offer such karaoke functions as echo, vocal canceling, and key
control on a single chip in addition to such digital signal
processing (DSP) features as sound field control and bass/treble
control.
Because the program and coefficients are stored on internal
ROM, the IC can be controlled by simple settings.
Features
Incorporates an AD converter (three channels) with 2 times oversampling.
THD: 65dB
S/N ratio: 80dB (typ.)
built-in pre-filter op-amp
Incorporates a -bit
-type DA converter (two channels).
THD: 86dB
S/N ratio: 93dB (typ.)
built-in tertiary analog post filter
Supports one port for digital input and one for digital output.
Incorporates 64 Kbits of delay RAM
Microcontroller interface: I2C bus mode as well as Toshiba’s original three-lead mode
Built-in boot ROM initializes coefficients at reset or via a boot command.
[Compatible Software]
Microphone echo: Variable delay time/level
Vocal cancellation: Attenuates only vocals from standard source
Vocal change: Vocals fade in/out depending on whether there is input from microphone
Vocal key control: For chorus and duet functions
Supports multi-sound sources: Various modes
Pseudo stereo: Monaural sources enhanced by sense of spaciousness
Key control: 4-step (max ± octave) stereo key control
Compressor or bass boost: Compression ratio selectable in range 6 to 36dB.
Compression effect (amount of boost) can be varied smoothly.
Sound field control: Uses delay RAM to simulate such acoustic environments as churches, halls, sports
stadiums, and discos.
Equalizer: Characteristics switchable by coefficient or I/F bit settings
3D sound field: Offers 3-D sound.
Weight: 1.08 g (typ.)
