DX ASSIST
Smart Tool for Preliminary Dialogue Editing

Key Features of DX Assist:


DXAssist is a standalone application for desktop computers. Runs on both Intel and Apple Silicon Macs, as well as on PCs.

After importing an AAF file, it analyzes the selected tracks and leaves only human speech, non-destructively removing unnecessary sound elements from the regions.

Its main purpose is the initial editing of lavalier microphone tracks.

The Vertical Editing option also allows you to remove crosstalk from other characters and choose the best audio sources.

It’s a huge time-saver — for example, a 55-minute TV episode containing six lavalier microphone tracks is processed in just 3 minutes and 30 seconds (on an Apple Silicon processor).

  • Automatic Dialogue Separation – Cut regions with silence, noise, and unwanted sounds while preserving speech. It works non-destructively — each region can be freely extended or merged.

  • AAF Format Support – Processes AAF files while maintaining track organization for efficient editing. All metadata from the AAF file are preserved.

  • Multi-Language Compatibility – Works with dialogue in multiple languages, making it ideal for global productions.

  • Adjustable Processing Parameters – Provides customizable settings to fine-tune the editing process to your needs. Includes ready-to-use presets and the option to save your own.

  • Designed for Professionals – Optimized for film, TV, podcast, You Tube and game audio post-production. Simply drag and drop a file — the program automatically adds the “.dxa” suffix to speed up your work.

You can add a few frames at the beginning and the end, which helps with applying fades.

With the VERTICAL PROCESSING parameter, DX Assist selects the best source by removing regions with crosstalk from other microphones.

A word from our users...

DXAssist saves me an incredible amount of time while keeping metadata intact. It’s already great - can’t wait to see what’s next.

– Benny Persson, Sound Designer, JUNI JULI studios

DXAssist is a fantastic time saver in my daily job. I use it on every project that has dialogue. Separating dialogue from other sounds has never been easier. Of course, you have to check and clean up after DXAssist but the workflow that developers suggest is quite good and useful. Check out their support videos.

- Ognjen Mihovilić, video and audio editor for TV entertainment shows

We use DX Assist in our two studios. At the moment, we’re working on a weekly broadcast series airing on a commercial TV channel. For us, the release of DX was a real lifesaver — it came at the exact moment we started post-production. Without it, we wouldn’t have been able to deliver our mixes on time. DX is a huge time saver for us.
