QuickTips: Adjusting audio filters visually in FCP X
FCP X has a pretty fantastic feature of showing waveforms adjustments on the fly, which can easily be seen by making volume adjustments to a clip. However, it doesn’t just work for volume adjustments but for filters as well, letting you make precise adjustments before you even listen to the clip.
The brilliance of this staggering. I’m not aware of any DAW that enables you to SEE the results of audio adjustments in real time (correct me if I am wrong). The feature lets you make adjustments in dynamics visually, as you perform them. Brilliant!
For example, here is a voice over with obvious background noise and a noise gate applied:
It can be clearly seen by examining the waveform that the noise is not being eliminated by the gate. So I’ll lower the threshold until and I can actually SEE the noise being eliminated:
Here is another example of a clip with a compressor applied but with a bit to much gain which introduces peaking:
So I enable the brick wall limiter, and adjust the threshold until the peaks are gone.
Wow!

Very nice. This feature was in STP as well.
All the best,

I just check this and actually the waveforms in STP were computed when filters were added to the “action list”, but only after you applied a filter, not while adjusting parameters, and it was a much slower process. The waveforms in FCP X redraw while you adjust parameters.
I just did a quick test and FCP X seems to compute the waveforms about 3x as fast as the beloved STP.

The wonders of faster processing.
