Online mastering for Spotify and every other platform
RefBooth masters your track for the platform you pick, at the target it publishes or −14 LUFS where it publishes none, or to figures of your own, and reads the result like every report. Mastering is part of Studio, with a 3-day trial.
Your report opens with a 3-day trial. Stored on our own servers in the EU, never used to train anything. Without an account it is deleted after 7 days. See a sample report
What you get
- A mastered copy at a platform’s true-peak ceiling and the loudness above, at the club convention, or at figures of your own.
- Three styles and three strengths: Warm, Balanced or Open, held lightly, moderately or tightly, so you can hear which suits the track.
- Saved as a new version of the track, beside the original, with its own full report: loudness, true peak, dynamics, stereo and spectrum, against the platform.
- A/B against the original at matched loudness, so you hear the master and not the level.
- Downloads as WAV or FLAC.
How it works
- Drop the track above. Its report shows where it stands against the platform now.
- Sign in with Studio, press Tools on the report, choose Mastering, and pick the platform or set your own target.
- The master arrives as a new version of the track with its own report. A/B it against the original, then download it.
Which target to choose
Spotify and SoundCloud publish −14 LUFS as their loudness target. Apple Music publishes a headroom rule rather than a loudness figure, and most other figures you see quoted are reported, not published, so RefBooth masters for those platforms at −14 LUFS and says so on the result. The loudness targets page gives each platform’s figure and its source, and the guide to mastering loudness explains what a target does to your track.
Limits and plan
- Mastering is part of Studio. Pricing has the price for your country.
- Each plan includes 20 tool runs a day, shared across the tools.
- The tools take tracks up to 15 minutes long.
- Studio starts with a 3-day trial. Cancel in those three days and nothing is charged.
Your files
Your track and its master are stored on our own servers in the European Union and never used to train anything. The master is kept like any track, while it is in your library. The privacy policy has the details.
Questions
Is online mastering free here?
No. It is part of Studio, with a 3-day trial first. Pricing has the price for your country.
What happens to my original?
Nothing. The master is saved as a new version beside it, and you can A/B the two at matched loudness.
Can I master to my own loudness?
Yes. Pick a platform and its ceiling is used, with the target it publishes or −14 LUFS where it publishes none; or set your own integrated loudness in LUFS and a true-peak ceiling in dBTP.
How do I know the master is right?
It gets its own full report, the same as any track: loudness, true peak, dynamics, stereo and spectrum against the platform, with what to fix first.
Before and after: the LUFS checker and the true peak checker. In both plans: the stem splitter and the vocal remover.
