21.6 Reverb and Echo
A click on FX in the
View Options - Show
brings up the Output FX panel. Here all parameters
for the effects Reverb and Echo are adjusted.
The Babyface Pro uses a DSP engine within its FPGA for all the
calculations of all the EQs and Low Cuts, in parallel to the TotalMix
DSP mixing engine. However, Reverb and Echo are calculated on the
host CPU - the computer. On current computers, this will not cause any
noticeable CPU load.
The transmission of the stereo signal FX Send to the computer and the
effects signal FX Out back to the Babyface Pro is done by two invisible
ASIO channels. The delay (latency) generated by this method is of no
consequence for the offered effects reverb and echo. But it is still taken
into account for the adjustment of the Reverb PreDelay. The lowest
value depends on the currently chosen buffer size (see Settings dialog,
chapter 8.1).
Reverb.
Activated by the On button.
Type.
Lists different reverb algorithms for selection. Available are:
¾
Rooms 1-4.
Reverb based on impulse responses with different
tonal colors. Room 1 and 2 sound dry and small, Room 3 and 4
brilliant and a bit bigger.
¾
Envelope.
Reverb out of single echoes plus feedback, where the
volume course (envelope) is freely adjustable.
¾
Gated.
Simpler version of the Envelope reverb for cut reverb
effects.
¾
Classic.
Classic multi-tap reverb with feedback, generating both
the typical sound and the very long reverb times.
Settings for Room 1-4
PreDelay.
Delay of the reverb signal. Adjustable from the current buffer size (some millisec-
onds) up to 999 ms.
Low Cut.
High-pass filter
before
the reverb generation, removes low frequency signals which
should not cause a reverb sound. Adjustable from 20 Hz up to 500 Hz.
High Cut.
Low-pass filter
after
the reverb generation. A reduction of the treble often lets the
reverb sound more natural. Adjustable from 5 kHz up to 20 kHz.
Room Scale.
Determines the size of the room, thus changing density and length of the reverb
effect. Adjustable from 0.5 up to 2.0.
