Audio Normalizer

What it does

Recordings from phones, social apps, and old rips often sit at uneven levels. Audio Normalizer adjusts gain so the signal reaches a target loudness using either peak or RMS measurement. Peak mode scales to a maximum sample level — useful when you want to avoid digital clipping while using full headroom. RMS mode aims at average energy, which can feel more natural for music with varying dynamics. Like the other edit tools here, normalization is pure client-side DSP: your audio is not sent to a remote API.

Peak vs. RMS audio normalization

Audio normalization adjusts gain to bring a recording toward a chosen level. Peak normalization measures the largest sample value and is useful for setting a ceiling. RMS normalization measures average signal energy and can make material with different average levels feel more consistent, although it is not the same as perceptual loudness or LUFS mastering.

Normalization applies gain; it does not repair distortion or dynamically compress loud sections. If the requested RMS target requires excessive gain, peaks may reach the digital ceiling and be clipped. Use a conservative target and listen to the exported WAV before replacing or sharing your original.

Set a useful level without changing the performance

Normalization applies a gain adjustment to the entire clip. It can make a quiet recording easier to hear or help bring several files closer to a common level, but it does not automatically even out every loud and quiet moment the way compression or automation would. The original dynamics remain largely intact unless clipping occurs.

Choose a target with enough headroom for the next stage of your workflow. Peak normalization is a straightforward ceiling-based option, while RMS gives an average-energy measurement. Because perceived loudness also depends on frequency balance and dynamics, always audition the processed version instead of relying on a number alone.

For tone shaping before normalization, open the Audio Equalizer. To remove silence or unwanted sections, use the Audio Trimmer.

How to use it

Tip: Leave a little headroom if you plan to apply EQ or other processing afterward, and keep the original file as a reference.
