About Chopper: Video/Audio Shortener
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
---------------------------------
- "Cut level" (the strength of the cut) can be adjusted in three levels.
- You can choose the export quality.
- Supports not only video but also audio files.
- You can also extract the audio from the video.
- You can also reduce the size (capacity) of the video. Select "Medium Quality".
