Part 3. Final Cut Pro Audio Editing Tips & Tricks

Of course, I understand that some of you might be getting started with Final Cut Pro audio editing tools. If that’s the case, I want to show you some helpful Final Cut Pro tips and tricks to make your audio editing experience worthwhile.

Learn the keyboard shortcuts – I know this might sound pretty obvious. However, mastering the keyboard shortcuts is always a welcome plus, especially if you’re using an advanced tool like Final Cut Pro X. For example, you can press C to select a clip when skimming in the timeline.

Turn off the magnetic timeline – Magnetic timelines is undeniably one of the main reasons why people avoid using FCPX. With the magnetic timeline, your audio will automatically become the next playing clip once you drag it down to the timeline. Although this can be a plus if you want to edit quickly, it can be a problem sometimes. Luckily, you can deactivate this feature by pressing P or setting the timeline to Position.

Maximize the rage tool – The rage tool is an underrated feature that will help you adjust audio settings easily. It applies to four keyframe elements and will help you lower or raise the audio volume effortlessly. Simply press R and lasso the section of your clip that you want to adjust.

Match the frames – Sometimes you might want to compare a clip in, let’s say, a browser to the one already in the timeline. To do that, just hit Shift + F and compare your clips. This should save you the stress of dragging out the timeline handless to see if there is anything left out.

Better sound editing – Everybody love high-quality results. So, to enjoy great sound editing, disable the video display on the timeline and then increase the wavefoam size. To do this quickly, you can press the light switch located in the bottom-right corner.


With these simple tips and tricks, you can edit sound on Final Cut Pro hassle-free. But if you find the platform to be too complicated, you can opt for the online alternative. With the Online UniConverter, you are sure of fast conversions, simple UI, and quality results. So, why not give it a try?
