21.6 Reverb and Echo
A click on FX in the View Options / Mixer Setup brings up the Output FX panel. Here all pa-
rameters for the effects Reverb and Echo are adjusted.
The Babyface uses a DSP engine within its FPGA for all the calculations of all the EQs and Low
Cuts, in parallel to the DSP engine for TotalMix. However, Reverb and Echo are calculated on
the host CPU, means 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 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 milliseconds) 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.
Smooth. Softens the reverb effect, affects stereo width, density and sound colour. Adjustable
from 0 up to 100.
Width. Adjusts the stereo width of the reverb signal from 100 (stereo) to 0 (mono).
Volume. Adjusts the level of the reverb effects signal sent to the FX return bus.
