Reverb (fig. 7)
Input channels: L, R
Output channels: L, R
This effect uses the same principle, except that
the delayed signal is the mixed output resulting in
a feed-back.
Chorus (fig. 7)
Input channels: L, R
Output chanels: L, R
For this effect, the "Delay" scheme is used, with a
variable delay lenght, in saw-tooth, from 0ms to
DELAY value.
DELAY_PERIOD specifies the period of the delay
variations.
Flanger (fig. 7)
Input channels: L, R
Output chanels: L, R
This effect uses the "Reverb" feed-back scheme
with the Chorus delay modulation mechanism.
3 Bands Equaliser (fig. 8)
Input channels: L, R
Output chanels: L, R
Three filters are put in parallel, and their output is
more or less attenuated by the corresponding
value (register BASS_L, BASS_R, MIDDLE_L,
MIDDLE_R, TREBLE_L, TREBLE_R).
The results are summed (or subtracted) through
an adder with the bypassed 12dB attenuated in-
put signal.
Loudness (fig. 8)
Input channels: L, R, C
Output chanels: L, R, C
The Loudness filter compensates for the ear fre-
quency response, boosting low and high frequen-
cies. The LOUDNESS register value (LOUD-
NESS_ON/LOUDNESS_OFF)
enables
or
disables this algorithm.
Volume Control (fig. 8)
Input channels: L, R, C, S
Output chanels: L, R, C, S
On each channel the volume attenuation value is
applied (register VOLUME_L, VOLUME_R, VOL-
UME_C, VOLUME_S). Moreover, the signals val-
ues are rounded to the bits number specified by
bits 0-3 of AUDIO_MODE register (16, 18, 20).
