The block diagram above illustrates the overall structure of the processing system provided by HaloVerb. The
diagram does not indicate the metering blocks.
Now lets examine the various processing blocks indicated in the diagram.
Prefilter
These controls set the frequency and level of the shelving pre-filters. Using these controls allows you to tailor
how much low and high frequency material is removed before the signal enters the reverb process.

Reverb
Let's take a look at what HaloVerb's parameters do, using the Reverb Impulse display. All controls will be
at the factory default except the control being discussed, so that you can see how that control changes the
reverb characteristics.
Please note that some combinations of settings will look similar in the impulse display, but will sound very
different.
Predelay
The Predelay control sets the time in milliseconds before the first reflection of the reverb is heard, up to a
maximum of 170 ms. When looking at the Reverb impulse, the predelay is seen as the time between the left
side of the window and the beginning of the impulse:
