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.

  • 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.
