Built for releasing your own music
Right for your platform
Pick a target such as Spotify, Apple Music or YouTube, and Quantara masters toward that platform’s loudness reference, with a true-peak-safe ceiling.
An honest before and after
The loudness-matched A/B plays your mix and the master at equal loudness, so you hear what mastering changed, not just that it got louder.
Your songs stay yours
Mastering runs on your device and your files are not uploaded for it. You keep full ownership of everything you master, and Quantara Music claims no rights in your music.
Try it before you pay
Try it with a free account: one free export per account (MP3 320, with a watermark), no card required. Exports without a watermark come with Pay Per Track, Pro or Studio.
Before you send a song to your distributor
- Master to the platform, not to the maximumPlatforms turn loud masters down. Aim for the reference of the platform that matters most to you — the Spotify guide explains why.
- Keep true peak below the limitLossy encoding can push peaks over 0 dBFS. Quantara keeps exports true-peak safe; the true peak guide explains the numbers.
- Export the format your distributor asks forMost distributors accept WAV. Export WAV, FLAC or MP3, depending on your plan.
Mastering only — release it anywhere
Quantara Music does mastering and nothing else. It does not distribute music or take royalties, so you can release through any distributor you like and keep your current setup.
