About this app

Tunelabs Pro puts a professional audio measurement lab in your pocket. Built for installers and serious tuners who need accurate, reliable tools — not guesswork. From your first speaker measurement to your final system verification, every step of the professional tuning workflow is covered in one app.

Set crossovers with confidence using automated DSP recommendations. Lock in perfect time alignment with temperature-compensated delay calculations. Verify phase coherence between drivers. Catch resonances and distortion before your client hears them. Tunelabs Pro gives you the same measurement capabilities that used to require expensive dedicated hardware — now running entirely on your Android phone, no internet required, no subscriptions, no hidden costs.

One purchase. The full toolkit. Measurement algorithms aligned with IEC 61260 and IEC 61672 industry standards — the same standards used by professional audio engineers worldwide.

1. 31-Band Real-Time Analyzer
Professional 1/3 octave RTA with frequency zoom, EQ target curve overlay, peak hold, and smoothing. See exactly what your system is doing in real time.

2. Automated Crossover Analysis
Measure each speaker, get instant HP/LP frequency, filter slope, filter type, and gain trim recommendations. Stop guessing crossover points — let the data decide.

3. Time Alignment Calculator
Zone-based delay calculation for Front, Rear, and Sub channels. Temperature-compensated speed of sound, cm/inch support, and experimental IR auto-measurement via your phone's mic.

4. SPL Meter
A and C frequency weighting (IEC 61672), broadband/RMS/peak SPL with reference lock. Match speaker levels precisely before you touch the EQ

5. Phase Analyzer
Detect polarity issues and crossover phase mismatches instantly. Live and reference-diff modes with cancellation zone highlighting — know exactly where your system is losing energy.

6. Spectrogram + Auto-Diagnostics
3D waterfall display with built-in diagnostic engine. Automatically detects resonances, harmonic distortion, dropouts, and noise floor problems — ranked by severity.

7. Professional Signal Generators
Band-limited Pink Noise with 8 frequency presets, phase-continuous Sine Wave across 31 ISO frequencies, and logarithmic Sine Sweep. Everything you need to drive your system during measurement

8. Calibrated Measurements
Import .cal/.csv mic calibration files for corrected frequency response. Noise floor profiling and external mic support (USB, wired 3.5mm) for measurement-grade accuracy.
