Offline Calculation Indicator
Manipulating the impulse response to reflect the controls settings requires recalculation of
the whole impulse response. This calculation process can take up to several seconds. While
the impulse response calculation is taking place, the reverb envelope graph displays
“Calculating…” and the audio is muted. After the calculations are performed, the graphs are
updated and the audio un-mutes.
ENVELOPE BYPASS: Range: ON/OFF. Default: Off.
This control bypasses all Envelope manipulations and allows you to audition the IR without
Gain Envelope manipulations. This does not bypass any of the IR manipulations such as
size or density; only the Gain Envelope is bypassed.
CLEAR ENVELOPE
This control deletes all envelope points and resets the envelope to its default unity gain.
REVERB DAMPING
This section controls the relative reverb time of the high and low frequencies.
The Reverb Damping controls allow you to modify the Low and Hi Frequency decay times
of the IR relative to its overall Reverb Time.
The controls are grouped together in a line, immediately above the Frequency Response
graph. From left to right you’ll see the low frequency ratio and frequency value (Hz), then
the high frequency ratio, and frequency value (Hz). This arrangement allows for easy
modification of both Ratios at the same time, by shift-clicking them and dragging to change
values.
Please Note: The Ratios are relative to the spectral properties of the original IR. For
example, an IR (remember: it is the measured response of a real space) may have a long
low-frequency decay time, but the low-frequency ratio would indicate the number “1”. This is
different from synthetic digital reverbs which use these types of controls to define the
frequency response of a room’s reverberation. With a synthetic reverb, the low frequency
ratio would have to be greater than “1”.
