Tuning Auto-Tune
Tuning Labs' most powerful feature: a 25-test AI system that measures, analyzes, and corrects your car audio in real time. One screen, three modes: Full Auto (fully automated, and the only mode that connects to the DSP), Semi-Auto (the AI tells you exactly what to adjust and you make each change on the DSP yourself) and Manual (the same tests with the AI off).

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: 12 tunes per month
Full Auto vs Semi-Auto vs Manual
🤖 Full Auto
The AI runs all 25 tests, makes corrections, writes them to the DSP, re-measures, and iterates — auto-advancing from test to test without stopping to ask. You come back when it's done. This is the only mode that connects to the DSP.
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 same 25 tests, each one started when you press Run. The AI computes the same corrections as Full Auto and tells you exactly what to adjust on your DSP — channel, band, frequency, dB, Q. Nothing is written for you: Semi-Auto has no DSP connection. You make the change, and the next measurement verifies it.
Each session opens with a one-time flat start: set every EQ band to 0 dB and enter each channel's current gain, so the AI knows your starting point. Before any test tone plays, the measurement mic checks the master level.
Best for: Technicians learning the process, fine-tuning an existing setup, or when you want full control.
- You see the exact instruction before each change
- You make the change on the DSP yourself, then press OK, Skip or Can't
- Great for teaching / learning
- AI coaching explains each decision
🧰 Manual is the same screen with the AI engine off: the same 25 tests, tone generators, graphs and score, each test on your Run button, no DSP connection, and it uses no token.
The 25-Test Sequence
Full Auto, Semi-Auto and Manual 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
