Mastering for your music, done in seconds
DZMASTER is an online tool that analyzes your WAV file right in your browser and automatically masters it to the correct loudness and safe peak level for Spotify, YouTube, Apple Music and everyday players.
How DZMASTER works
No parameters, no tweaking. Pick the platform you're releasing to and the tool handles the rest.
Upload a WAV
Drop your file into the browser — it stays on your device and is never uploaded.
Pick a preset
From 9 platform presets (Streaming, Apple/Podcast, Club/EDM, Broadcast, Vinyl and more) — or let Smart Auto decide based on the track's analysis.
The tool masters it
Loudness is matched to the target LUFS and a safe limiter protects the peaks from clipping.
Download the result
Grab the finished WAV and upload it straight to Spotify for Artists, YouTube or Bandcamp.
A preset for every platform
