DecibelRTA is an ultra-fast, professional real-time acoustic analyzer combining a fractional-octave IIR spectrum analyzer and an advanced IEC sound level meter on a unified display. Engineered with a native, zero-latency DSP core, DecibelRTA displays 11 vital acoustic metrics simultaneously without requiring navigation through menus: 11 METRICS AT A SINGLE GLANCE • Instant Spectral Pitch: Dominant musical note (e.g. A#2), frequency (Hz), and exact level (dB). • Core Metrology Chips: Leq 5s (equivalent continuous level), ACUM (psychoacoustic sharpness), LRA (Loudness Range dynamic spread), L50 (median ambient level), and CRST (crest factor). • Standard SPL Bar: SLOW (1s), FAST (125ms), and instant PEAK decay monitoring. HIGH-PRECISION SPECTRUM ANALYZER (RTA) • 3, 6, 12, and 24 bands per octave constant-Q filter bank (up to 240 selective IIR bands). • Contextual dual-path engine delivering sharp low-frequency transient tracking below 280 Hz. • Real-time spectral centroid, active -3 dB bandwidth marker, and continuous peak-hold curve. • Linear regression spectral tilt line (beta) for instantaneous noise color identification (pink, white, brown noise). • Built-in industry reference target curves (Flat, Audiofrog, Harman Room, JBL House, B&K Optimum) with a ±3 dB tolerance corridor. IEC 61672 SOUND LEVEL METER & STATISTICS • Type-standard A-weighting with true-RMS exponential ballistics (FAST / SLOW). • Continuous 5-second sliding Leq and sliding statistical histogram (L10, L50, L90). • Dual-mode dynamic range: Studio Mode (30 to 100 dB) and LIVE Mode (50 to 120 dB). • Fast overload CLIP warning and color-coded acoustic safety levels. BUILT FOR SOUND PROFESSIONALS • Live sound engineers & FOH: Quick feedback detection and stage SPL limits. • Studio & Mastering: Mix tonal balance, dynamic compression (LRA), and high-frequency fatigue check (ACUM). • Car Audio & Hi-Fi: In-cabin acoustic calibration and speaker alignment against target curves. • Acoustic & Industrial Hygiene: Noise floor surveys (L90) and OSHA/NIOSH threshold tracking. Microphone access is strictly processed on-device in real-time. No audio data is ever recorded, stored, or transmitted.
