Make Audio Louder, Quieter or Normalize It
A recording that is too quiet or too loud is easy to fix: move the slider to raise or lower the volume in decibels (+6 dB is about twice as loud), or choose normalization.
Normalization brings the sound to a standard loudness, like streaming services do, so several tracks play at the same level without clipping. Files are deleted from our server automatically after 48 hours.

Frequently Asked Questions
Is this tool free?
Yes, it is completely free, with no registration and no watermark.
What is the difference between louder and normalize?
Louder adds the same number of decibels to the whole file, which can cause clipping on loud parts. Normalization measures the loudness and adjusts it to a standard level safely.
Which formats are supported?
MP3, WAV, M4A, OGG, FLAC, AAC, Opus, WMA, AMR and videos (MP4, MOV, MKV, WebM, AVI). The result is MP3, WAV, OGG or M4A.
Are my files safe?
Files are sent over an encrypted connection and deleted from our server automatically after 48 hours; you can delete them earlier in "Your files".
