Transport Buttons
The Editing area contains two transport buttons:
 Play: Starts or stops playback of the selected audio track. You can also use the Space
bar to start or stop playback.
 Cycle: Engages/disengages Cycle mode. When Cycle mode is engaged (the button is
darkened), playback of the selected track repeats continuously.
Editing Functions
Impulse Response Utility offers three editing functions, accomplished via the two
editing buttons at the top left of the Editing window: Cut, Crop, and Fade.
All edit functions are accomplished by using the same steps:
1 Click-drag over a portion of the audio in the Editing area.
2 Click the appropriate edit function button.
 Crop: If you make a selection that doesn’t extend to either the beginning or end of
the audio, the left edit button activates the Crop function. Clicking this button will
remove the audio to the right and left of your selection, without touching the
selected audio. You can also choose Edit > Crop (or press Command-X) to crop.
 Cut: If you make a selection that extends to either the very beginning or very end of
the audio, the left edit button activates the Cut function. Clicking this button will
remove the selected audio, without touching the unselected audio. You can also
choose Edit > Cut (or press Command-X) to cut.
 Fade: If you make a selection that includes either the very beginning or end of the
audio, you can select the Fade function. Clicking this button creates a gradual fade
over the length of the selection area. You can also choose Edit > Fade (or press
Command-F) to fade.
Note: In order to maintain phase coherency between all tracks of your impulse
response, edits are performed across all tracks equally. To ensure that your impulse
response cannot include tracks that are not edited equally, you are prevented from
recording further tracks once an edit has been made.
