TuneHelper

Store description excerpt

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. You bring the mic and REW — TuneHelper brings lab-grade signals to the driver's seat.
