Chopper: Video Silence Remover2.6.2 - App Store

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!
