This is the first official release of DX Assist, and we're excited to finally share it with you.

We know many of you have been waiting — and asking — for early access, which is why we decided to make the app available now, even as we continue to actively develop and improve its features.

We’re working hard to add new tools, refine performance, and respond to your feedback — so don’t hesitate to reach out if you spot a bug, have a suggestion, or just want to say hi.

Below you’ll find a handful of useful details and known issues we’re currently working on.

1. Parameters.
‍
Probability determines how strict DXAssist is when detecting speech. Higher values cause elements like breaths, drawn-out word beginnings, and other speech-like sounds to be considered unnecessary and removed. It's recommended to experiment with settings in the range of 20% to 80%.

Strip Start and End Pad add a specified number of frames at the beginning and end of each region after processing. This is useful if you plan to add fade-ins and fade-outs later. However, keep in mind that setting the values too high may cause the regions to merge again.

Min Strip Gap defines the minimum gap that should remain between the cut regions. If the user finds the cuts between words too sharp and wants to maintain smoother continuity, this value can be increased. However, once again, setting it too high may result in regions being merged.

Vertical Processing is a new feature that processes material after the initial “horizontal” cuts are made. At this stage, audio bleed from other tracks may remain, since the program may recognize bleed from secondary lavaliers as speech. When Vertical Processing is enabled, the program attempts to choose the version that should be kept.

Caution is advised when using Vertical Processing and adjusting parameters other than Probability, as it may cause this function to behave incorrectly. We recommend keeping all parameters other than Probability within a range of 1–2 frames. Otherwise, the current version of the algorithm may remove too many regions due to overlapping results. This is the first fix planned for version 1.1.

A video explaining how use Vertical Processing can be found in the Workflow section.

‍2. Supported AAF formats.
‍
At this stage, DXAssist supports the WAV format contained within AAF files. We do not currently support MXF or AIFF formats. Additionally, due to the nature of the algorithm, we only support time division based on frames, not milliseconds. Expanding this functionality is one of the features we plan to develop in the future.

3. Troubleshooting

If program reads the AAF file but stops at the first clip and does not continue processing this means that the AAF contains formats that DXAssist currently does not support, such as MXF or AIFF. In this case, the best solution is to open the AAF in Pro Tools and re-export it using WAV embedded. A video explaining how to do this can be found in the Workflow section.
-
If nothing happens after pressing the Process button in the trial version, it may indicate that there is no content within the first 3 minutes of the AAF — which is the time range the trial version processes.To test the app properly, you should prepare an AAF file that contains audio from the very beginning.
-
Since we aimed to make the algorithm support all languages and work fully offline (DXAssist runs without internet access and only requires it to activate the license), there may be cases where it doesn't recognize short words, drawn-out syllables, or various accents.
It may also fail to treat singing as speech and remove it, as well as breaths and similar vocal noises. We're continuing to improve the algorithm, but for now, you may need to manually correct such cases.
-
If the program is removing too many regions where dialogue should remain, please try running the Process with Vertical Processing turned off, Probability set to 10–20%, and all other parameters set to 2 frames.
