WHY USE THIS TOOL

Raise or lower audio level with fixed gain controls

Use this general volume tool when you need either direction: increase a quiet source or reduce a loud one before sharing, editing or another workflow.

Boost quiet audio

Positive gain makes the signal louder, subject to available headroom.

Reduce loud audio

Negative gain can lower a file before mixing or sharing.

Choose output format

Keep MP3 for portability or select another supported audio format.
