FILTER MODE
In the quad-filter mode two stereo signals are accepted
(see Fig.6). DC filtering is performed at the inputs before
further processing. A correction can be performed on the
input signals using a 4-band graphic equalizer, i.e. 8 poles
and 8 zeros can be placed arbitrarily in the Z-domain.
At the output, different delays can be applied to the
4 channels via the external DRAM. The interfacing and
addressing of the DRAM is performed by the DAPIC.
The application for this mode is in 4-channel correction
applications such as car and home audio systems.
S
TEREO EXPANSION MODE
In the stereo expansion mode one stereo signal is
accepted (see Fig.7). DC filtering is performed at the
inputs before further processing. A 4-band graphic
equalization is first performed after which a complex
stereo expansion is applied. A room effect can be added
by the addition of early reflections.
The applications for this mode are in the headphone
out-of-head and incredible stereo applications.
