Your DSP cost €800. You're still guessing.
The car audio DSP platform for diagnostics, system blueprints, and guided tuning. Guides free.
- No opaque "auto-tune": every crossover and gain stays visible and editable.
- We don't sell hardware, just the method to tune yours.
- No promise of perfect sound: a procedure you drive, step by step.
You bought the Focal K2 kit (~$3950). You paid $200-300 for a pro tuning session. The core of our app does the same and more — it keeps refining over time, like a sound engineer who reminds you to re-check (Refinement Lab). And that core is free.
