Browser Audio Editor
Batch trim MP3 tracks and export each clip.
Load multiple MP3 files, switch between tracks in one workspace, define a separate clip for each song, preview the selection, and save every trimmed result as its own MP3.
The normalization toggle is peak normalization, which is a practical browser-side way to make clips more consistent, though it’s not the same as full LUFS loudness normalization.

How it works
The editor decodes your MP3 files locally in the browser, stores a separate clip range for each track in the batch list, and re-encodes each chosen slice as its own downloadable MP3.
