About WOW DB Meter & RTA
WOW DB Meter & RTA turns your iPhone and iPad into a professional-grade acoustic measurement tool and real-time audio spectrum analyzer (RTA). Engineered with precision DSP algorithms and fluid 60 FPS GPU-accelerated graphics, it is the ultimate tool for audio engineers, acoustic consultants, studio musicians, live sound technicians, and car audio enthusiasts. KEY FEATURES: • PRECISION DECIBEL (SPL) METER - Accurate real-time sound pressure level measurement in dB. - Industry-standard frequency weighting curves: dBA (human hearing response), dBC (bass/industrial sound), and dBZ (unweighted flat response). - Configurable response times: Fast (125ms), Slow (1000ms), and Room Impulse (2000ms). - Dynamic analog-style circular gauge with live peak indicator, numerical readout, and minimum / average / maximum dB stats tracking. • REAL-TIME AUDIO ANALYZER (RTA) - High-resolution Fast Fourier Transform (FFT) spectrum analysis with Hann windowing. - Multi-band octave band views: 1/1 Octave (10 ISO standard center bands) and 1/3 Octave (31 precision bands). - Pro 1/6 Octave High-Resolution mode (61 bands) for surgical room mode inspection and feedback suppression. - Continuous spectral curve mode with lingering peak decay indicators. - Interactive touch-to-inspect bar feature displaying exact frequency (Hz) and amplitude (dB). • MULTI-TARGET ACOUSTIC CURVES - Overlay reference acoustic targets directly onto your live RTA to tune speaker systems and home theaters: - Harman Target Curve (+6dB bass shelf) - Studio Flat (Reference calibration) - SMPTE 202M X-Curve (Cinema sound tuning) • BUILT-IN PINK NOISE GENERATOR - Integrated high-fidelity pink noise generator using the Kellet algorithm for room equalization, speaker voicing, and frequency response analysis. - Live output volume attenuation slider. • HARDWARE CALIBRATION & MIC PROFILES - Pre-calibrated hardware profiles optimized for Apple iPhone and iPad internal microphones. - Manual SPL trim adjustment (±15 dB) with one-tap 94.0 dB external calibrator reference mode. • RESPONSIVE STUDIO WORKSPACE - Optimized for both portrait handheld metering and landscape full-screen RTA visualization. - Native iPad split-view and tablet support.
