Normalize to a dBFS or LUFS target, compare the original and processed audio, then export WAV, MP3, M4A, FLAC, or OGG locally.
Drop music, speech, or a recording here to normalize its level, or import from:
Set the maximum sample level for the complete file.
An audio normalizer measures a complete file and applies a controlled level change to reach a chosen peak or perceived-loudness target. Peak and loudness normalization solve different problems, so both methods are available in one workflow.
Match the highest sample in the complete file to a precise dBFS target without changing its internal dynamics.
Measure the complete program in Integrated LUFS and match its perceived overall level to a delivery target.
Set a dBTP ceiling in loudness mode to reduce the risk of inter-sample peaks exceeding the destination limit.
Review the original level, normalized level, gain change, and method-specific secondary measurements before exporting WAV, MP3, M4A, FLAC, or OGG.
The same uploaded file can be processed with either normalization method.
Select Peak Normalization for a dBFS target or Loudness Normalization for a LUFS target.
Choose music, speech, a recording, or a video file with an audio track.
Pick a preset or enter a custom value. Loudness mode also lets you choose a True Peak ceiling.
Normalize the complete file, compare the original and result, then export WAV, MP3, M4A, FLAC, or OGG.
Choose the method based on whether the destination cares about the highest digital sample or the perceived loudness of the complete program.
| Method | Measurement | Best for | Result |
|---|---|---|---|
| Peak normalization | Sample peak in dBFS | Samples, sound effects, and technical headroom | Applies one constant gain change and preserves the existing dynamics |
| Loudness normalization | Integrated LUFS with True Peak in dBTP | Podcasts, music, video, and complete programs | Matches perceived level; True Peak limiting may be used when the requested target needs it |
LUFS presets are practical references. Always confirm the current requirement supplied by the platform, broadcaster, client, or distributor.
Choose the mode based on how the destination evaluates audio level.
Use peak normalization to give a collection of clips consistent maximum headroom.
Use loudness normalization to make complete episodes or voice recordings feel consistently loud.
Match a LUFS reference and True Peak ceiling required by a platform or production workflow.
Normalization changes delivery level. It does not repair clipping, noise, uneven editing, or a poorly balanced mix.
Lowering a clipped recording cannot reconstruct peaks that were already distorted in the source.
One normalization pass does not automatically balance individual words, speakers, instruments, or sections inside the file.
Use EQ, compression, limiting, noise repair, or mastering tools when the audio needs more than an overall level adjustment.
Peak Normalization matches the single highest sample to a dBFS target. Loudness Normalization measures perceived level across the complete program and matches an Integrated LUFS target.
Peak normalization applies one constant gain change and preserves the existing dynamics. Loudness normalization also targets program loudness and uses True Peak control, but it is not a replacement for creative compression or mastering.
Loudness Normalization is usually more useful for podcasts because it matches perceived level across the complete episode.
Peak Normalization is usually the direct choice when you want predictable maximum headroom for short samples or sound effects.
Files selected from your device are decoded and normalized locally in the browser.
Edit one or more audio files with a browser-based timeline and export in popular formats.
Batch compress up to 10 files and export MP3, M4A, OGG, or configurable PCM WAV.
Match a sample-peak or LUFS target, compare the original and normalized audio, then export WAV, MP3, M4A, FLAC, or OGG.
Set the peak, shape lows, mids, and highs, control the final ceiling, compare, and export a mastered WAV.
Boost audio up to 300% or normalize it to a consistent -16 LUFS level.
Select a waveform section, add fades, loop-preview it, and export for iPhone or Android.
Select a waveform section, repeat it, smooth every join, then slow down, speed up, transpose, and export.
Update embedded title, artist, album, date, genre, track, comments, and supported cover art.
