Volume Level Guide

0x — Mute

Completely removes all audio from the video. Perfect for adding your own soundtrack or silent videos.

0.5x — Quiet

Reduces volume by half. Useful for background videos where the audio should not be distracting.

1x — Normal

Keeps the original audio level unchanged. Use this as a reference point.

1.5x — Louder

Increases volume by 50%. Good for videos that are slightly quiet.

2–3x — Amplified

Significantly boosts quiet recordings. Boosting too high may introduce audio clipping/distortion.

Frequently Asked Questions

Boosting beyond the original signal ceiling causes audio clipping (distortion). 2x is usually safe; 3x may cause distortion on already-loud audio. Use headphones to test.

No — volume adjustment only modifies the audio stream. The video track is copied without re-encoding, so visual quality is preserved completely.

This tool changes existing audio volume only. To replace or add a new audio track, you would need a video editing application like DaVinci Resolve or CapCut.
