Frequently asked questions
Everything you need to know about SetMaster Pro.
What is SetMaster Pro?
SetMaster Pro is an online audio mastering service built specifically for DJ mixes. You upload your mix file, choose a mastering profile suited to where your mix will be heard (club, streaming, podcast, or warm analogue), and receive a professionally mastered file - typically within 1-3 minutes.
Who is SetMaster Pro designed for?
SetMaster Pro is built for club DJs, radio presenters, podcast hosts, and anyone who records DJ mixes. If you want your mix to sound polished and broadcast-ready without hiring a mastering engineer or learning audio production software, SetMaster Pro is for you.
What file formats can I upload?
You can upload WAV, MP3, FLAC, AIFF, OGG, and M4A files. For best results, we recommend uploading a WAV or AIFF file as these are lossless formats that give the mastering engine the most information to work with. MP3 and M4A files are accepted but the quality ceiling is limited by their original compression.
How large can my upload file be?
File size limits depend on your plan: Free - up to 1GB; Pro - up to 3GB; Studio - up to 5GB (WAV files are capped at 3GB across all plans, which is approximately 3 hours of audio at standard quality).
How long does mastering take?
Most mixes complete in 1-3 minutes. Longer files or periods of high server load can extend this slightly. Studio plan users are prioritised in the processing queue.
What mastering profiles are available?
There are four profiles: Streaming / Radio (targets -14 to -12 LUFS, optimised for Spotify, Apple Music, and Mixcloud); Club / Festival (aggressive limiting and smile-curve EQ for large PA systems); Podcast / Radio Show (vocal clarity boost targeting -16 LUFS for podcast platforms); and Warm / Analogue (tape and tube saturation for a vintage, smooth sound). The Streaming / Radio profile is available on the Free plan; all four profiles are available on any paid plan.
What output formats are available?
Free plan users receive a 320kbps MP3. Paid users can choose between 320kbps MP3 or a lossless WAV (16-bit / 44.1kHz).
How long are mastered files available to download?
Mastered files are available for 24 hours after processing completes on all plans. After that the file is permanently deleted from our servers. We recommend downloading and backing up your master as soon as it is ready.
What is the audio watermark on the free plan?
Free plan masters include a short SetMaster Pro promotional audio clip at the start and end of the file. Upgrading to Pro or Studio removes the watermark and delivers a completely clean master.
Can I master the same file more than once?
Yes. Each submission counts as one mix against your monthly allowance, regardless of whether it is a new file or a re-upload of the same mix.
What happens when I reach my monthly mix limit?
You will not be able to start new mastering jobs until your allowance resets at the start of the next calendar month. You can upgrade to a higher plan at any time to increase your limit immediately.
How is DJ mix mastering different from track mastering?
Track mastering focuses on a single piece of music - controlling dynamics, EQ, and loudness for a standalone release. DJ mix mastering handles a continuous recording that may span hours, multiple genres, and varying recording levels. Our profiles are tuned specifically for this longer-form content, targeting the loudness and tonal balance appropriate for each playback environment.
Is my audio kept private?
Yes. Your files are stored in private cloud storage and are never shared or accessible to other users. Only you can access and download your masters. Files are permanently deleted 24 hours after processing.
Can I cancel my subscription?
Yes, at any time from the Billing page inside your dashboard. You retain access to your plan until the end of the current billing period, and you will not be charged again after cancellation.
Can I publish my master directly to SoundCloud?
Yes - Pro and Studio users can publish their mastered mix to SoundCloud in two ways. From the dashboard upload page, enable 'Publish to SoundCloud' before you click Upload & Master: fill in the track details (title, artwork, artist, genre, tags, description) and it will publish automatically the moment mastering finishes - fire and forget. Alternatively, from your History page you can click 'Publish to SoundCloud' on any completed master at any time. Connect your SoundCloud account first from the Profile page in your dashboard.
Can I upload directly to Mixcloud from SetMaster Pro?
Yes - Pro and Studio subscribers can upload mastered mixes directly to Mixcloud without exporting. After mastering finishes, hit 'Upload to Mixcloud' and your mix goes live on your profile. Connect your Mixcloud account from the Profile page in your dashboard.
What is the difference between the export and the Mixcloud upload?
The export downloads a file to your computer (MP3 or WAV). The Mixcloud upload sends your mastered mix directly to your Mixcloud profile, so it is available to stream immediately - no downloading, no switching apps.
Do I still need to export to MP3 if I am uploading to Mixcloud?
No - the direct Mixcloud upload handles everything. You only need to export if you want a file for your computer or to upload to other platforms manually.
Which tiers get Mixcloud uploads?
All paid tiers - Pro (£4.99/mo), Studio Lite (£9.99/mo) and Studio (£24.99/mo). Free tier does not include publishing to SoundCloud or Mixcloud.
What should I do if my mastering job fails?
Check your History page - failed jobs are shown clearly. The most common cause is a corrupted or unsupported file. Try re-uploading the file. If the problem persists, contact us at contact@setmasterpro.com and we will investigate.
