How to boost the volume of a Audio file

  1. 1

    Drop in the too-quiet or too-loud recording. Audio and video files both work.

  2. 2

    Pick Normalize to hit the broadcast loudness standard, or choose a straight multiplier up to 3×.

  3. 3

    Hit Fix the volume and download the corrected file. Normalize is the safe choice when you are not sure.

Why fix the volume here

Broadcast-grade normalize

The Normalize option runs EBU R128 loudness normalization, the standard broadcasters and podcast platforms measure by: not a blunt gain knob.

Multipliers when you want them

Half, 1.5x, 2x or 3x, applied evenly across the whole file. Simple and predictable when you already know how far off the level is.

Audio and video alike

Drop in an MP3, WAV, M4A or a whole video: if it has sound, the level gets fixed the same way.

No watermark, no signup

Free for everyday use, and files delete themselves from our servers within an hour.

Loudness vs volume: why Normalize usually wins

A multiplier scales every sample by the same factor. That is fine until the loud parts are already near the ceiling: push past it and they clip into crunch. And doubling the numbers does not double how loud a track feels, because hearing works on a roughly logarithmic scale.

Normalize measures the whole file the way ears do, in loudness units (LUFS), then adjusts it to the EBU R128 broadcast target. Quiet recordings come up, hot ones come down, and peaks are kept from clipping.

Streaming platforms run their own loudness normalization anyway: Spotify and YouTube pull everything toward roughly -14 LUFS at playback. Blasting a file to 3x before uploading there just gets turned back down. Consistent loudness is what actually survives the trip.

Questions people ask

Will this work with every Audio file?

Depends entirely on the format it lands in. If a stubborn Audio refuses, run it through the converter first: a clean rewrap fixes most oddballs.

What does Normalize do exactly?

It measures the file's loudness and adjusts it to the EBU R128 broadcast standard, the same target podcasts and streaming platforms use. Quiet parts come up without the loud parts clipping.
