 EQ button: Click this button to switch the main display to Space Designer’s four-band
parametric EQ. See “EQ Parameters” on page 138 for more information on Space
Designer’s EQ.
 Reverse button: Click to reverse the impulse response together with its envelopes.
When you reverse the impulse response, you are effectively using the tail rather than
the front end of the sample. As such, you may need to use lower or even negative
Predelay values when reversing.
Additional View Items in Envelope View
When displaying envelopes, the main display offers a few other buttons and an
overview that is not part of the EQ view:
 Impulse response overview: Indicates which portion of the impulse response file is
currently visible, helping you to orientate yourself when zoom is active.
 Zoom to Fit button: Switch on to display the entire impulse response waveform. The
display will automatically follow any envelope length changes.
 A and D buttons: Click to limit the Zoom to Fit function to the attack and decay
portions of the (currently selected) envelope. The A and D buttons are available only
to the volume and filter envelopes.
Setting Envelope Parameters
Space Designer allows you to edit the volume and filter envelopes of all IRs, and the
density envelope of synthesized IRs. All three envelopes can be adjusted both
graphically and numerically (in the parameter bar).
While some parameters are envelope-specific, all envelopes consist of the Attack Time
and Decay Time parameters: The combined total of the Attack Time and Decay Time
parameters is equal to the total length of the (synthesized or sampled) impulse
response (determined by the Length parameter, see “Setting the Length of the Impulse
Response” on page 124), unless the Decay time is reduced.
