Common questions
Will a volume booster fix background noise?
Gain raises the recording and any noise already in it. If hiss or traffic is already audible, listen to the boosted result before exporting.
What file formats can I use?
Choose MP3, WAV, M4A, or another audio format your browser can decode. Wavebench exports a new WAV file. The original stays unchanged.
How is this different from normalization?
Volume Booster applies the gain you choose. Audio Normalizer measures each file and adjusts it toward your chosen loudness target.
