Before
After - Mastered
Four profiles. Every venue.
Each profile is a carefully tuned EQ, compression, and limiting chain - built for where your mix will actually be heard.
Club / Festival
Loud & PunchyAggressive peak limiting with a smile-curve EQ - sub-bass boost and crisp highs. Built for main rooms and large PA systems.
Streaming / Radio
BalancedTargets -14 to -12 LUFS - the sweet spot for SoundCloud, Mixcloud, Spotify, Apple Music. Flat, transparent, streaming-safe.
Podcast / Radio Show
Vocal ClarityBoosts the 2-5kHz vocal range and applies dynamic ducking so host segments cut cleanly through the music.
Warm / Analogue
Smooth & DeepSubtle tape and tube saturation. Rolled-off harsh highs, thickened low-mids. For lounge, deep house, and techno.
Built different.
This isn't a volume booster. It's a full professional mastering chain - running on dedicated servers so your laptop never breaks a sweat.
The Invisible Hand Leveler
Every long mix has a quiet track hiding somewhere in the middle. Our auto-leveler reads ahead and smoothly rides the gain up over several seconds - so the energy stays locked in without audible pumping or compression artefacts.
LUFS Normalisation
Your master is measured and targeted to the exact integrated loudness standard for your chosen destination. Streaming platforms won't duck your track. Club profiles are pushed as loud as the format allows.
Brickwall Limiter
A lookahead true-peak limiter applies a hard -1 dBFS ceiling as the final stage. Your master will never clip - on any playback system, any DAC, any stream.
One-Click Multi-Platform Distribution
Connect once. After mastering, push your mix directly to SoundCloud and Mixcloud - no re-exporting, no switching tabs. Pro and Studio subscribers get access to both platforms. Perfect for DJs managing radio shows, residencies, or multiple streaming channels.

Common questions.
Will this work on a 2-hour continuous mix?
Yes. The engine is specifically built for long-format content. Files up to 5GB are handled without any processing on your machine. Processing time scales with file length - Studio tier users jump the queue.
My mix has a very quiet older track in the middle - will that get fixed?
Yes. The auto-leveler analyses the incoming audio and rides the gain to compensate for level drops between tracks. It does this gradually and transparently, without audible pumping or compression artefacts.
What loudness target does the Streaming / Radio profile use?
-14 LUFS integrated, with a -1 dBFS true-peak ceiling. This matches the normalisation targets used by Spotify, Apple Music, YouTube Music, and most major streaming platforms.
Can I upload WAV and get WAV back?
Yes, on any paid plan. Free tier outputs 320 kbps MP3 only.
How long are my files stored?
Input and output files are available for 24 hours after processing, then permanently deleted. We do not archive your audio.
What is the audio watermark on the Free plan?
Free tier masters include a short SetMaster Pro audio ident at the start and end of the file. It is removed on all paid plans.
Does SetMaster Pro use AI?
No. SetMaster Pro runs digital signal processing - compression, EQ, limiting and saturation - tuned by hand for four playback contexts (streaming, club, podcast and warm analogue). The chain is deterministic: the same input produces the same output every time. No machine learning, no opaque model. Results are predictable and adjustable, which matters when you need consistency across a release schedule.
