Questions
Is the audio loudness booster free?
Yes, 100% free. No sign up, no watermark and no limits.
Does my file get uploaded?
No. Your file never leaves your device. Everything happens right in your browser, so it stays private and works on unreleased tracks, beats and voice memos too.
Why is my audio file so quiet?
It was probably recorded too far from the mic or at a low level. Boosting it here brings it up to a normal level.
How do I make it louder?
Drop the file in the box. It starts at +12 dB. Press Play to check, then click Export MP3.
Will it also make background noise louder?
Yes, boosting raises everything. For very noisy recordings, boost a little at a time.
What file types can I use?
Any audio your browser can play: MP3, WAV, M4A, FLAC, OGG and more. Save the result as MP3 or WAV.
No sound on my iPhone?
Turn off silent mode (the switch or Action button on the side), turn up the volume, and press Play again. Older iPhones mute web audio in silent mode.
