How good the AI based silence removal is?
---------------------------------

Conventional silence cutters (based on audio levels) cannot cut out noise, rustling, etc.

This apps 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
