TuneHelper
Car-audio measurement signals
$1.99 · Designed for iPad. Not verified for macOS.
Real-time pink noise, sweeps, bursts, impulses and polarity — plus stereo correlation, hands-free L/R and per-driver band noise. Tune your car with REW.
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
• Polarity test — L/R phase check
STEREO TOOLS
• Correlation modes — correlated, uncorrelated or anti-phase
• Auto L/R — hands-free alternation between the speakers
• Per-driver band noise — sub, woofer, midrange and tweeter presets
• Anti-phase sine and a subsonic / high-pass finder
WHY TUNEHELPER
• 100% real-time synthesis — every signal generated live, never a looped buffer
• Click-free start, stop and switching
• Live spectrum analyser, oscilloscope and RMS metering
• Background audio — keeps playing with the screen locked
PRIVACY
No accounts, no tracking, no data collection. All settings stay on your device.
