AD1953
–12–
quality of compressed audio. In addition, the main channels
have a stereo widening algorithm that increases the perceived
spread of the stereo image.
Most of the signal processing functions are coded using full 48-bit
double-precision arithmetic. The input word length is 24 bits,
with two extra headroom bits added in the processor to allow
internal gains up to 12 dB without clipping (additional gains can
be accommodated by scaling down the input signal in the first
biquad filter section).
A graphical user interface (GUI) is available for evaluation of
the AD1953 (Figure 3). This GUI controls all of the functions
of the chip in a very straightforward and user-friendly interface.
No code needs to be written to use the GUI to control the chip.

SIGNAL PROCESSING
Signal Processing Overview
Figure 2 shows the signal processing flow diagram of the AD1953.
The AD1953 is designed to provide all common signal-processing
functions commonly used in 2.0 or 2.1 playback systems. A
7-biquad equalizer operates on the stereo input signal. The
output of this equalizer is fed to a 2-biquad crossover filter for
the main channels, and the mono sum of the left and right equalizer
outputs is fed to a 3-biquad crossover filter for the Sub channel.
Each of the three channels has independent delay compensa-
tion. There are two high quality compressor/limiters available:
one operating on the left/right outputs and one operating on the
subwoofer channel. The subwoofer output may be blended back
into the left/right outputs for 2.0 playback systems. In this
configuration, the two independent compressor/limiters provide
2-band compression, which significantly improves the sound
