Tuning Auto-Tune
Tuning Labs' most powerful feature: a 25-test AI system that measures, analyzes, and corrects your car audio in real time. Available in Full Auto (fully automated) or Semi-Auto (you approve every correction).

The Dependency Tree — What Auto-Tune Needs
Auto-Tune has hard prerequisites. Every item on this list must be complete before it will start. This is intentional — skipping any step produces inaccurate results.
- DSP model must be selected
- Channel map must be complete
- At least one speaker role mapped
- USB connected to the processor
- WebHID permission granted
- State successfully read from DSP
- Measurement mic connected
- Calibration (.cal) file uploaded
- At least one RTA capture taken
- Harman, Audiofrog, Flat, or Custom curve active in RTA
- Audio Enthusiast: 6 tunes total
- Shop Small: 3 tunes per month (additional available)
- Shop Large: 25 tunes per month
Full Auto vs Semi-Auto
🤖 Full Auto
The AI runs all 25 tests, makes corrections, writes them to the DSP, re-measures, and iterates — without stopping to ask. You come back when it's done.
Best for: Shops tuning many vehicles. Technician sets it up and moves on to other work.
- Fully automated — no interaction needed
- One correction per pass (worst offender first)
- Re-measures after every write
- Stops when within target curve tolerance
🧑🔧 Semi-Auto
The AI runs each test, shows you what it found and what it recommends, then waits for your approval before writing anything to the DSP.
Best for: Technicians learning the process, fine-tuning an existing setup, or when you want full control.
- You see the recommendation before each write
- You can accept, reject, or adjust the value
- Great for teaching / learning
- AI coaching explains each decision
The 25-Test Sequence
Both Full Auto and Semi-Auto run the same 25 tests in the same order. The sequence is derived from the Tuning Labs Academy's PhD-level course on acoustic measurement and DSP calibration.
Phase 1 — Preflight (Tests 1–8)
These run before any audio correction. They verify the system is ready and establish baseline measurements.
| # | Test | What It Checks |
|---|---|---|
| 1 | DSP Connection Verify | USB link alive, state readable |
| 2 | Mic Calibration Check | Cal file present, valid frequency range |
| 3 | RTA Initialization | Mic input live, signal-to-noise ratio acceptable |
| 4 | Noise Floor Measurement | Ambient noise level — flags if too high for accurate measurement |
| 5 | Channel Polarity Check | Confirms no wiring phase inversions |
| 6 | Channel Level Balance | Left/right channel matching within tolerance |
| 7 | Crossover Verify | Confirms crossover points are in the expected range for each speaker role |
| 8 | Baseline Capture | Records the "before" frequency response for all channels |
Phase 2 — Correction (Tests 9–16)
The AI analyzes the baseline, identifies problems, and applies corrections one at a time.
| # | Test | What It Does |
|---|---|---|
| 9 | Sub-Bass Correction (20–80 Hz) | EQ correction for low bass region |
| 10 | Bass Correction (80–200 Hz) | EQ correction for mid-bass region |
| 11 | Upper Bass Correction (200–500 Hz) | EQ correction for upper bass / warmth region |
| 12 | Lower Midrange Correction (500–1kHz) | EQ correction for lower midrange / male vocals |
| 13 | Midrange Correction (1–3kHz) | EQ correction for presence / female vocals |
| 14 | Upper Midrange Correction (3–6kHz) | EQ correction for upper midrange / attack |
| 15 | Treble Correction (6–12kHz) | EQ correction for air / sibilance region |
| 16 | High Treble Correction (12–20kHz) | EQ correction for upper air extension |
Phase 3 — Verification (Tests 17–25)
After corrections are applied, the system re-measures and verifies the results.
| # | Test | What It Verifies |
|---|---|---|
| 17 | Post-Correction Capture | Full frequency response after all EQ changes |
| 18 | Target Curve Deviation | How close to the target curve we are (dB error per band) |
| 19 | Polarity Re-Check | Corrections didn't introduce phase issues |
| 20 | Channel Balance Re-Check | L/R balance still maintained post-correction |
| 21 | Crossover Integrity | Crossover slopes still appropriate post-EQ |
| 22 | Sub Integration | Sub-to-satellite handoff smooth and in-phase |
| 23 | Dynamic Range Check | No clipping at normal listening levels |
| 24 | Headroom Verify | Adequate headroom before DSP clipping |
| 25 | Final Score | Overall system score (0–100) based on all metrics |
How the AI Applies Corrections
Here's the loop for each correction pass:
Auto-Tune running — the AI has completed preflight and is now in the correction phase. The actual vs. target overlay shows progress.
Reading the Results
Frequency Display
- Line graph (top) — actual vs. target curve overlay. The closer the actual line is to the target, the better the correction.
- Bar graph (bottom) — per-band deviation in dB. Green bars = within tolerance. Red bars = still needs correction.
Test Progress
- Each of the 25 tests shows pass (✅), fail (❌), or in-progress (⏳)
- The final score appears after Test 25: 0–100 overall system rating
- Detailed breakdown: per-zone scores for Sub, Bass, Midrange, Treble, and Integration
