Quiet recordings are a common problem — a voice memo captured too far from the phone, a video's audio track that's noticeably lower than everything else in your library, or a song ripped at a low gain. Our free volume booster amplifies your audio file by a gain multiplier you control, making it louder without needing an audio editor.

Upload your file, drag the gain slider to the boost level you want, and download the louder result. Push the gain too far on already-loud material and you may hear clipping or distortion, so it's worth previewing the result before committing to a large boost.
