Why use Aback Video for this
Boost without clipping
A limiter catches peaks when you boost, so loud moments do not crackle.
Loudness normalisation
Two-stage EBU R128 measurement brings quiet and loud recordings to the same perceived level.

Frequently asked questions
How many dB should I add?
Every 6 dB roughly doubles the signal level; 10 dB sounds about twice as loud. Start there and go higher only if needed.
Will boosting add noise?
Background noise gets louder along with the voice. Run Reduce Background Noise afterwards if the hiss becomes noticeable.
How many dB should I add?
6 dB sounds roughly one and a half times as loud, 10 dB about twice as loud. Start with 6 and increase if needed.
What is LUFS and which target should I use?
LUFS measures perceived loudness. YouTube and Spotify play at about -14 LUFS, Apple Podcasts suggests -16, and broadcast uses -23. Normalising to the platform's level keeps your video from sounding quieter than others.
Will boosting a very quiet recording make it sound good?
It will be louder, but background noise rises too. Run Reduce Background Noise first if hiss becomes obvious.
Is the picture re-encoded?
No. For videos, only the audio is processed and the video stream is copied.
Is my file uploaded?
No. The volume change is done by FFmpeg inside your browser.
Can I use this on a phone?
Yes. It is quick on phones because only the audio is processed.
