Frequently asked questions
Will boosting distort my audio?
A soft limiter bends peaks smoothly instead of clipping. Very large boosts still flatten dynamics — use Normalize for consistent levels.
Can I boost a video's volume?
Add the video to extract and boost its audio; to keep the picture, use the video tools.
What's a dB?
+6 dB roughly doubles the signal level; +10 dB sounds about twice as loud.
