TuneHelper
Car-audio measurement signals
$1.99 · Designed for iPad. Not verified for macOS.
TuneHelper turns your phone into an instrument-grade measurement-signal generator for car-audio DSP tuning. Stream its output into your car over Bluetooth, USB-C or a 3.5 mm cable and measure the result with REW (Room EQ Wizard) and a calibrated microphone.
Every signal is synthesized in real time, sample by sample — no pre-rendered loops, no audible seams — at a precise, honest dBFS level you can re-tune live from the driver's seat.
SIGNALS
• Pink & white noise — continuous, loop-seamless
• Log sweep & sub sweep — frequency response and impulse
• Tone bursts — transients and decay
• Periodic pink noise — synchronous averaging in REW
• Dirac impulses — impulse response
• Sine tone — 20 Hz to 20 kHz, with optional anti-phase
• 1/3-octave band noise — 32 ISO 266 bands
• Stepped-sine RTA — a tone walking all 32 band centres, hands-free
• Multitone comb — up to 64 tones at once, the instant RTA
• Gated pink burst — DSP settling and room decay
• Synthetic kick drum — sub-to-front time alignment by ear
• Brown noise — heavy low end for rattle hunting
ALIGNMENT & STEREO TOOLS
• Inter-channel delay dial — ±5 ms in 0.01 ms steps, read the value off in ms and cm
• Correlation modes — correlated, uncorrelated or anti-phase
• Auto L/R — hands-free alternation between the speakers, optionally via the phantom centre
• Per-driver band noise — sub, woofer, midrange and tweeter presets
• Anti-phase sine, a subsonic / high-pass finder and a rattle hunter with marks
WHY TUNEHELPER
• 100% real-time synthesis — every signal generated live, never a looped buffer
• Click-free start, stop and switching
• Live spectrum analyser with optional A/C weighting, RMS metering and a clip LED
• Auto-pause — cycles play and silence for hands-free averaging in REW
• Save and recall measurement presets
• Background audio — keeps playing with the screen locked
PRIVACY
No accounts, no tracking, no data collection. All settings stay on your device.
You bring the mic and REW — TuneHelper brings lab-grade signals to the driver's seat.
Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
• NEW: Stage balance — one band of noise at a time, pushed left or right until it sits in the centre. At the end a table for your DSP and REW's EQ table per channel.
• Seven frequency regions from sub-bass to air, shared by driver noise, multitone and the impulse.
• Auto L/R moves with the signal; the ten-second check plays every element at every position.
• Tidier tabs: parameter cards fold away.
• The distortion trainer is gone.
• Many fixes platforms.
