DuckFlow

What is DuckFlow?

DuckFlow is a smart audio ducking extension designed for video editors and motion designers who like to listen to music or other audio while working inside After Effects or Premiere Pro.

The problem is that external audio (music players, notifications, etc.) mixes with the timeline audio. Every time you want to play the timeline, you have to manually mute the player, play the timeline, and then unmute it again. This breaks your workflow and wastes time.

DuckFlow solves this problem automatically.

How It Works

When DuckFlow is active, it monitors your timeline playback in real-time.
As soon as you press play, it automatically lowers the volume of all external audio players (Spotify, YouTube, VLC, notifications, etc.) to the level you set.
The moment you stop the timeline, the external audio returns to its original volume all without any manual muting.

  • Timeline Play:
    External audio volume drops automatically
  • Timeline Stop:
    External audio returns to normal instantly
  • Seamless Experience:
    No manual muting required

Works with After Effects & Premiere Pro

DuckFlow works seamlessly with both After Effects and Premiere Pro one purchase covers both applications.

Cross-application support:
Enable it once and it works across both apps. Whether you're editing in Premiere or animating in After Effects, DuckFlow automatically activates on whichever timeline you play. No need to toggle between extensions or restart anything just focus on your work and let DuckFlow handle the audio.

Enable / Disable Toggle

The main toggle button lets you enable or disable DuckFlow with a single click.
When enabled, the extension will automatically duck external audio when the timeline is played.
When disabled, everything works normally.

Keyboard Shortcut

For quick access and convenience, DuckFlow supports keyboard shortcuts to enable or disable the extension without opening the panel. Simply set your preferred key combination in the settings and use it to toggle DuckFlow on or off instantly, even while working in full-screen mode. This allows you to stay focused on your creative work without any interruptions.

⚠️ Limitations

Currently, DuckFlow is only available for Windows. Due to differences in audio handling between operating systems, this extension does not work on macOS at this time. However, a similar plugin called Doppler is already available for After Effects on macOS.
