Set Space Designer impulse response lengths in Final Cut Pro for Mac
You can use the Space Designer effect’s Length parameter to set the length of the impulse response.

- 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. - To add the effect and show its controls, see Add Logic effects to clips in Final Cut Pro for Mac. 
- Rotate the Length knob to set the length of the impulse response—sampled or synthesized. - The Length knob setting changes the decay value, depending on the current Size knob value. To clarify, a Length value of 100% and a Size value of 100% result in a decay that is the full length of the loaded impulse response. - All envelopes are automatically calculated as a percentage of the overall length. Changes to the Length or Size parameter values result in envelope curves stretching or shrinking to fit the new impulse response length. - Note: When you’re using a sampled impulse response file, the combined Length (and Size) parameter values cannot exceed the length of the underlying impulse response sample.
