Master your DJ mix.
In minutes, not hours.
Upload your mix, master it in minutes, and push it straight to Mixcloud and SoundCloud. Built for club DJs, radio hosts, and podcasters who want pro results without the pro-studio price tag.
DJ mix mastering in three steps.
No plugins. No DAWs. No audio engineering degree required.
1. Upload
Drop your mix - WAV, MP3, AIFF, FLAC, OGG, M4A. Up to 12 hours (Studio). Files go direct to secure cloud storage, no browser crashes.
2. Choose profile
Club, Streaming, Podcast, or Warm Analogue. Four mastering chains tuned for your playback environment.
3. Download or publish
Get a broadcast-ready MP3 or WAV - or push it straight to your Mixcloud or SoundCloud profile without leaving the app. Pro and Studio only.
Hear the difference.
The same DJ mix - before and after SetMaster Pro. No EQ tweaking, no plugins.
Streaming / Radio
BalancedSet to the level SoundCloud, Mixcloud, Spotify and Apple Music play back at.
Before
After - Mastered
Four profiles. Every venue.
Each profile shapes your mix for where it'll actually be heard - streaming, the club, a podcast feed, or a warmer listen.
Club / Festival
Big & PunchyVoiced for club PAs, festivals and DJ software - bigger low end, crisper highs, sub-bass summed to mono below 50 Hz so it stays tight on a large system.
Streaming / Radio
BalancedClean and balanced for SoundCloud, Mixcloud, Spotify and Apple Music - set to the level they play back at, so it arrives at the loudness they expect.
Podcast / Radio Show
Vocal ClarityLifts the voice so hosts cut cleanly through the music - the broadcast standard for podcasts and radio shows.
Warm / Analogue
Smooth & DeepA warmer, vinyl-style tone - softer highs and a fuller low end. 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. Each platform plays back at its own loudness target; a master set to that target plays as delivered. The Club profile is mastered louder, for USB sticks, car systems and PA playback that are not loudness-normalised, with peaks held below clipping.
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.
Fix the recording before it is mastered.
Four optional switches on the upload page. Off by default; with them off, your master comes out exactly as before.
Clipping repair
The “Repair clipped recording” switch
A mixer pushed into the red leaves the loudest peaks flattened. This finds those spots, rebuilds the peaks from the audio either side, and holds them below clipping. A lightly clipped set comes back clean; a heavily clipped one comes back better.
Vinyl cleanup
The “Vinyl cleanup” switch
For a set recorded from turntables. Takes out mains hum when it is clearly there and repairs surface clicks by rebuilding the audio either side of each one. Works on clicks shorter than 3 ms; deep scratches and skips are left as they are.
Multi-mix upload
The “Add more mixes” button under the drop zone
Pick several mixes, set the profile, format and destinations once, give each its own title, and click once. Close the page when the uploads finish; an email arrives as each master is ready.
Rumble and DC offset removal
The “Remove rumble and DC offset” switch
Strips the sub-audible rumble and offset that turntables, line-ins and older recorders leave behind, before mastering starts. On a clean digital mix it changes nothing.

What DJs are saying
“Amazing! - Such a massive difference to the playback quality on soundcloud! So simple to use too. Saved me hours of time. Thanks.”
“Absolutely fantastic. Such a difference!”
Common questions.
Will this work on an extended mix?
Yes. The engine is built for long recordings - long mixes, radio shows and recorded streams. Mixes up to 12 hours are handled without any processing on your machine.
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.
Can SetMaster Pro fix a clipped recording?
It can repair one. The Repair clipped recording switch finds the flat-topped peaks a mixer or recorder left when it went into the red, rebuilds each peak from the audio either side of it, and holds the rebuilt peaks below clipping. A lightly clipped set comes back clean, a heavily clipped one comes back better. Studio Lite and Studio.
Does SetMaster Pro clean up vinyl recordings?
Yes. The Vinyl cleanup switch removes mains hum when it is clearly there and repairs surface clicks shorter than 3 ms; deep scratches and skips are left as they are. Pro and above, with a High click setting on Studio Lite and Studio.
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's the difference between Free and a paid plan?
Free gives you one master a month (two in your first month) with the Streaming / Radio profile as a 320 kbps MP3. Paid plans unlock all four mastering profiles - including Club / Festival - WAV and MP3 downloads, more masters a month, and one-click publishing to SoundCloud and Mixcloud.
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.
