Description
This app can automatically remove silences in your video/audio by detecting human voice using AI.
It can be used for audio, too.
Good for YouTube, podcasts, etc.
---------------------------------
How good the AI based silence removal is?
---------------------------------
Conventional silence cutters (based on audio levels) cannot cut out noise, rustling, etc.
This app's AI (deep learning) technology identifies only the "human voice" and can remove those unnecessary parts.
---------------------------------
All is done on-device!
---------------------------------
All processing is done on the iPhone/iPad, so you can use it offline.
No data is sent to the server, so you can rest assured of security and privacy.
---------------------------------
How to use
---------------------------------
Just select a video and tap the "Export" button!
---------------------------------
Features of Chopper

What’s New
Version 2.4.1

Ratings and Reviews
This app is amazing
But it worked better a couple of weeks ago. There was an update with watermark removal. Since then, it leaves silence in the video. Sometimes the silence will last several seconds. Prior to the update, the app worked perfect and there was complete silence removal.
Please fix this developer because I love this app!!

Did not work as advertised
I didn’t have high expectations before downloading the app, but since there aren’t many options for iPad I went with this. I imported the video, and nothing happened. I watched the video on their app, but it kept running smooth with not a single cut.
Developer Response ,
Version 2.4.0 has significantly improved cutting accuracy. We hope you will try it again.
