About Louder Video: Volume Booster
You can't make out a word anyone is saying. The video is simply too quiet.
Pick that video, and its volume is raised automatically — as far as it can go without letting the sound clip.
No multiplier to choose. No editing app to learn.
HOW IT WORKS
1. Choose a video.
2. Save the louder version to Photos, or share it.
There is nothing to decide in between. The app measures the audio itself and works out how far to raise it.
IT DOES NOT DISTORT
The usual problem with turning audio up is that it starts to crackle. A limiter holds the peaks under the ceiling the whole way through, so the result does not clip.
Before you save, play the original and the louder version back to back on the result screen, and hear the difference for yourself.
YOUR PICTURE IS UNTOUCHED
The video track is copied across exactly as it was. Only the audio is re-encoded. Image quality does not change, and the export finishes quickly.
WHEN IT HELPS
- A school concert or sports day filmed from the back row
- A meeting or lecture recorded from across the table
- An interview you need to listen back to
- A clip someone sent you that you keep replaying to catch the words
EVERYTHING STAYS ON YOUR IPHONE
Your video is never uploaded. All processing happens on the device. There is no server, no analytics, and not a single third-party SDK in the app.
It asks for one permission only: adding to Photos. It never asks to read your photo library.
The temporary files it creates are deleted the moment you leave the result screen.
PAY ONCE
Buy it once and that is it. No in-app purchases, no monthly or yearly subscription, no ads.
WHAT IT DOES NOT DO
- It cannot remove noise. Background sound gets louder too.
- It cannot repair audio that was already distorted when it was recorded.
- Videos that are already loud enough are left alone, so nothing is degraded for no reason.
- Videos with almost no sound are left alone, because raising them would only amplify hiss.
- There is no volume multiplier to set by hand.
- There is no trimming, joining, or background music.
PLEASE NOTE
The processed video plays noticeably louder than the original. Turn your device volume down before you play it with earphones.
The comparison on the result screen plays sound even when the silent switch is on, so that you can judge the loudness.
Requires iPhone with iOS 17.0 or later.
