What it fixes in an EDM mix
General-purpose mastering treats a supersaw drop like an acoustic ballad. DropMastr listens for the things that go wrong in electronic music.
A sub that hits everywhere
Bass below about 120 Hz is folded to mono, so it doesn't vanish on club rigs or cancel out on a phone speaker.
Highs that shine without the sting
Harsh supersaw peaks get turned down only at the moment they spike. The rest of your top end stays bright.
Glue that leaves the kick alone
The bus compression ignores the kick when deciding how hard to work, so the mix tightens up without pumping.
Loud, but never crushed
We push to your target loudness and stop before the limiter starts to distort. If your mix can't get there cleanly, the report tells you why.
Pick the sound you make
Each style has its own tonal target, loudness and low-end handling. More genres are on the way.
- Melodic EDM
Melodic house, progressive, trance, future bass. Wide pads, clean sub, smooth top end.
- Bass Music
Dubstep, riddim, drum and bass, trap. Heavy sub, aggressive, loud.
- House & Techno
Punchy kick and a steady groove, with dynamics kept for the club.
- Festival
Big room and electro drops built for maximum impact.
- AI musicBeta
For Suno and Udio tracks. Tames the metallic shimmer and harsh highs that AI audio is known for.
DJ mix mode
For hour-long YouTube and SoundCloud mixes. Evens out level and tone between tracks from different producers.
Reference matching
Upload a track you love and DropMastr matches its tone, loudness and width.
Album and EP mode
Drop several tracks at once. They share one tonal target and land at the same loudness, so the record plays back to back evenly.
Hear the real difference, not just "louder"
Louder always sounds better at first, which is how most mastering previews win you over. DropMastr plays your mix and the master at the same volume, and you can flip between them mid-drop without the music stopping, so you judge the sound itself.

Questions
What should I upload?
Your final mix, exported as WAV or AIFF at 24-bit if you can. Take any limiter or clipper off the master bus and leave a few dB of headroom. MP3 works too, but a lossless file gives a cleaner master.
How loud will my master be?
That depends on the style and intensity you pick. Melodic EDM on balanced lands around -9 LUFS, bass music around -7.5. You can also pick a loudness-normalized master for streaming or a YouTube mix setting.
Is this AI mastering?
It's an automated mastering chain that measures your track and adapts to it: tone, low end, stereo width, harshness and loudness, all tuned per genre. The report shows every move it made.
Can I use it on music made with Suno or Udio?
Yes. The AI music profile is in beta and is tuned for the brittle high end and smeared transients common in generated tracks.
What happens to my files?
Your uploads and masters are kept for 7 days so you can come back and download them, then deleted. We never use your music to train AI or share it with anyone.
Can I cancel Pro anytime?
Yes. Cancel from your account and you keep Pro until the end of the period you paid for.
