Use the Space Designer IR Sample mode in Final Cut Pro
In IR Sample mode, Space Designer loads and uses an impulse response recording of an acoustic environment. This is convolved with the incoming audio signal to place it in the acoustic space provided by the IR.
Activate IR Sample mode
In the Final Cut Pro timeline, select a clip with the Space Designer effect applied, then open the effect’s settings in the Audio inspector.
For information about adding the effect and showing its controls, see Add Logic effects to clips in Final Cut Pro.
Click the IR Sample button in the circular area to the left of the main display, and then select an impulse response file from any folder.
Note: If you already loaded an impulse response file, clicking the IR Sample button switches the mode from Synthesized IR to IR Sample mode.
Manage the loaded IR file
In the Final Cut Pro timeline, select a clip with the Space Designer effect applied, then open the effect’s settings in the Audio inspector.
For information about adding the effect and showing its controls, see Add Logic effects to clips in Final Cut Pro.
Click the down arrow next to the IR Sample button to open a pop-up menu with the following commands:
Load IR: Loads an impulse response sample without changing the envelopes.
Load IR & Init: Loads an impulse response sample and initializes the envelopes.
Show in Finder: Opens a Finder window that shows the location of the currently loaded IR file.
All impulse responses that ship with Final Cut Pro are installed in the /Library/Audio/Impulse Responses/Apple folder. Deconvolution files have the file extension .sdir.
Any mono, stereo, AIFF, SDII, or WAV file can be used as an IR. In addition, surround formats up to 7.1, discrete audio files, and B-format audio files that comprise a single surround IR can also be used.
