Louder, without
the distortion.
Fix the recording that came out too quiet, or bring a mixed bag of files to the same level. Boost by up to 18 dB with a limiter that stops clipping, or let loudness normalization measure each file and set it for you.
one loudness tool.
Boost when one file is too quiet
A voice memo recorded across the room, a lecture captured from the back row, a track that plays noticeably quieter than everything else in the queue. Pick the gain in dB, preview it live, and render with a limiter so pushing hard does not turn into crackle.
Normalize when files disagree
Five recordings from five sources will play at five volumes. Loudness normalization measures each file the way streaming platforms do and brings every one to −14 LUFS with a true-peak ceiling — the whole batch comes out at the same perceived level without touching a slider.

Drop in up to five tracks — MP3, OGG, WAV, FLAC, and more.

Boost by a dB amount you can preview live, or normalize the batch to −14 LUFS.
