Surgical Precision with the Visual Threshold Editor

You no longer have to guess your audio levels. FCP AutoDuck NX allows you to vividly visualize your dialogue waveform. You can set the perfect threshold to trigger your music ducking, even when dealing with notoriously low-volume audio. Simply drag and drop the visual lines directly on the waveform to set exactly when the ducking should trigger and release. It provides absolute total control, combined with incredible visual convenience.

Advanced Multi-Track & Role-Based Support

Forget the limitations of the past. The brand new engine of FCP AutoDuck NX features a completely redesigned user interface built to handle the most complex editing workflows. It is no longer limited to just your soundtrack: you can now seamlessly duck sound effects simultaneously! The application supports up to four simultaneous audio paths: Dialogue, Music, Sound Effects, and Filler. Organizing and routing your timeline audio has never been this powerful and intuitive.

Smooth, Professional Radio-Style Transitions

A phenomenal audio mix shouldn't be "noticed"—it should flow naturally. Avoid those harsh, abrupt, and annoying volume jumps by taking advantage of dedicated parameters like "Attack" and "Pre-roll", which intelligently anticipate and soften the audio transitions. Furthermore, by utilizing the "Hysteresis" setting, you ensure that your background music doesn't awkwardly snap back to full volume between sentences, but instead waits for the perfect moment of silence. Achieve recording studio results right at your editing desk.

How It Works: A Flawless Workflow

1. Export Your Audio Roles From Final Cut Pro, simply export your project Audio Roles (Dialogue, Music, and Sound Effects) as separate, high-quality audio files. Setting your timeline to Lanes view makes this incredibly easy and ensures the app analyzes the cleanest possible tracks.
2. Drag & Drop (Auto-Detect) Drag your newly exported files directly into the FCP AutoDuck NX window. You can drop them into their specific colored panes, or just drop them anywhere and let the app's smart engine auto-detect which track is which based on your roles.
3. Process the Audio Instantly Click the "Duck" button. Wait just a few moments for the blazingly fast processing engine to analyze the waveforms, and then choose which Final Cut Library you want to save the new timeline into. FCP AutoDuck NX calculates and plots every single keyframe for you automatically.
4. Import and Enjoy the Results Copy the beautifully ducked music and effects from the FCP AutoDuck timeline, return to your original edit, mute the old flat tracks, and paste the new files at the start. You now have a perfectly balanced, professional mix ready for export.
