Start here
One account. Two places.
UniVerseCity is a school and a city for mixing engineers. You learn and prove your skills on the Campus. You meet artists, producers and work in the City. Creating an account is free.
The Campus
Where you train.
For mixing engineers, from first steps to expert.
- 7 levels named after record plaques, from Vinyl to Icon
- Lessons with sound examples before every test
- 186 tests: ear training, quizzes, decisions, hands-on mixing
- Unlimited practice, with the answer explained every time
- Ranked exams that earn your plaques
- Monthly mix competitions
The City
Where you connect.
For engineers, artists and producers.
- A public profile with your plaques, your sound and your mixes
- Artists and producers looking for an engineer
- Swipe-style matching for collabs, near you or anywhere
- Messages, and paid work posted by artists
How they connect: every plaque you earn on the Campus appears on your City profile. Artists don't have to take your word for it: they see what you've proven, and hear your mixes.
How the Campus works
Learn it. Practice it. Prove it.
You don't need any experience to start. Every level follows the same four steps.
- 1
Read the lesson
Every level starts with lessons: plain-language text and sound examples you can switch between while they play.
- 2
Practice
Take any test as often as you like. After every answer you see what was right and why. Nothing counts yet.
- 3
Pass the ranked exam
When you're ready, take the ranked version: one try per test per day, in full screen. Pass it on 3 different days and the test is cleared.
- 4
Earn the plaque
Clear every test of a level (and from Gold up, a mix reviewed by people) and the plaque is yours. The next level opens.
The way we teach
There are no good or bad frequencies.
Most tutorials teach you to boost a band by 10 dB, sweep until something sounds horrible, and cut it. With a 10 dB boost, everything sounds horrible. You end up cutting what was fine and tiring your ears.
Here you learn to listen to a track the way it is, hear what's out of balance, ringing or fighting, and make only the moves the song needs. That's how experienced engineers work, and it's what every lesson and test trains.
Six kinds of tests
- ListeningHear a change and name it: which band was boosted, which version is compressed, how big is the room.
- QuizKnowledge you need behind the console: what a control does, where an instrument lives.
- DecisionA real situation and several possible moves. Every answer is graded: best, acceptable, weak or harmful, with the reason.
- Hands-onReal faders and EQ in your browser: rebuild a balance, match a boost, set safe levels.
- MemoryPure tones and references you learn by heart, like 100 Hz, 1 kHz and 10 kHz.
- ProjectA real song to mix in your own studio, with your own plugins. Compared with expert mixes, and reviewed by people from Gold up.
The rules, in plain words
- Practice is unlimited
- Repeat any test as much as you want. That's how ears are trained.
- One ranked try per test per day
- You can't brute-force a plaque by retrying fifty times in a row.
- Three different days
- Passing on three days proves the skill is real, not a lucky guess.
- Full screen, no other tabs
- Leaving the exam (another tab, an analyzer) cancels the question.
- Loudness-matched sound
- Versions are level-matched, so you can never answer by picking the louder one.
- Mixes reviewed by people
- From Gold up, plaques also need a real mix reviewed by the panel.

Level 4 · Gold
Dynamics and character

Know more than anyone in the room.
Not presets. Not beginner tips. The techniques behind award-winning records: the physics, the circuits and the decisions, taught by working engineers and tested by ear.
Compression, from the circuit up.
- FETFast, aggressive and colored. Why it makes vocals and drums bite.
- OpticalA light-driven release that breathes. Why opto feels musical on vocals.
- VCAPrecise and punchy. The bus compressor that glues a mix together.
- Variable-muTube gain reduction that thickens the sound as it works harder.
- Digital look-aheadTransparent control, and when it removes the life from a track.
