Choose audioDrag an audio file onto the box or click to browse. The tool measures its peak and loudness instantly.
Normalize to a peak ceiling to preserve dynamics, or to a loudness (RMS) target to match levels across clips.
See the exact gain being applied, then download as MP3 or WAV. Normalize as many files as you like.
Normalize to a peak ceiling for headroom, or to an average loudness so clips match each other.
The tool shows the file’s measured peak and RMS, plus the exact gain it will apply before you export.
Analysis and processing run on your device — nothing is uploaded.
Give every episode or clip the same target so listeners never reach for the volume.
Normalizing means applying a single, constant gain so your audio hits a chosen level. Unlike compression, it doesn’t change the dynamics — it just moves everything up (or down) by the same amount. This tool measures your file with the Web Audio API and applies the gain locally.
Peak mode raises the loudest sample to your chosen ceiling (for example −1 dBFS). It’s the safe default: it maximizes level without ever clipping and keeps the natural dynamics intact.
Loudness mode targets the average level instead, which is what makes several clips feel equally loud. The tool automatically holds back the gain if it would push the peak into clipping, so quiet and loud recordings end up matched and clean.
