Question 1

What does "audio normalization" actually do?

Accepted Answer

It analyzes your file's loudness and applies gain so the track hits a target loudness level, measured in LUFS (Loudness Units Full Scale) — the same standard streaming platforms use. Unlike a simple volume boost, it accounts for how loud the track sounds overall, not just its peak level.

Question 2

Which target loudness should I pick?

Accepted Answer

-14 LUFS matches Spotify and YouTube's streaming target. -16 LUFS is common for podcasts and Apple Music. -23 LUFS is the EBU R128 broadcast standard. -9 LUFS is louder, closer to club/EDM masters. If you are not sure, -14 LUFS is a safe default for most uploads.

Question 3

Will this clip or distort my audio?

Accepted Answer

No. The normalizer caps true peaks at -1.5 dBTP (decibels true peak), the same ceiling most streaming platforms recommend, so the result stays free of inter-sample clipping even after gain is applied.

Question 4

How is this different from just turning up the volume?

Accepted Answer

A manual volume boost multiplies every sample by the same factor, so a track with loud choruses and quiet verses keeps that same gap. Loudness normalization targets the perceived average loudness (LUFS), which is what makes tracks sound consistently leveled next to each other.

Question 5

Which audio formats are supported?

Accepted Answer

MP3, WAV, OGG, and M4A are all supported as input. The normalized file is saved in the same format as the file you uploaded.

Question 6

Why does the first use take longer than expected?

Accepted Answer

The first time you use any audio/video tool on this site, your browser downloads a ~30MB audio/video-processing engine (ffmpeg compiled to WebAssembly), cached afterward for instant use across all audio/video tools.

Question 7

Is my audio file uploaded to a server?

Accepted Answer

No. All analysis and processing happens entirely in your browser using WebAssembly — your file never leaves your device.
