Soniclyze: SPL & RTA Meter

Noise, room & loudness tools

Free · In-App Purchases · Designed for iPad. Not verified for macOS.

RTA, SPL, and audio file analysis — all free. No external audio interface required. Pro unlocks PDF/CSV/JSON reports and unlimited-duration measurement. Soniclyze turns your iPhone and iPad into a professional sound measurement toolkit — and the core is free. Measure SPL, analyze frequency response in real time, inspect audio files, detect feedback, and export clean reports. No external audio interface required. Algorithms are implemented with reference to IEC, ISO, ASTM, and ITU-R standards. **For noise & environmental monitoring** Long-duration sound level measurement with A/C/Z weighting and Fast/Slow/Impulse time constants. Full statistics: Leq, Lmax, Lmin, Lpeak, L10, L50, L90, and SEL. Adaptive noise-event detection logs each event's level, duration, and rise/fall rate. NIOSH/OSHA noise-exposure dose for occupational settings, and automatic zone-limit assessment per GB 3096-2008. If a call or Siri interrupts a measurement, Soniclyze pauses and marks the interrupted interval automatically, then lets you continue. **For live sound engineers** High-resolution real-time spectrum analysis (standard ~11.7 Hz; EPPO low-frequency mode down to ~0.73 Hz, FFT up to 65536). Octave-band resolution from 1/1 to 1/24. Six window functions including Flat-Top for pure-tone amplitude work. Real-time feedback detection. Microphone sensitivity correction (via known mV/Pa spec, optional 94 dB reference calibrator). Five built-in industry reference room-correction target curves spanning cinema, broadcast, and home-theater traditions, plus A/B/C/D snapshot comparison for before/after tuning. **For broadcast, podcast & mastering** Loudness and true-peak analysis (Integrated / Short-term / Momentary LUFS, LRA, 4x oversampled true peak), with compliance checks against 11 industry loudness targets spanning broadcast (EBU R128, ATSC A/85), streaming, podcast, cinema, and CD mastering. Anomaly detection for DC offset, clipping, spectral notches, transcoding artifacts, and band limiting. Multi-band phase/polarity inversion analysis (8-band + full-band) and mono compatibility. Play and analyze at once: waveform, spectrum, and waterfall views stay in sync as you audition. **Toolbox** Signal generator, parametric EQ designer, FIR filter designer, acoustic calculators, and frequency-response export. **Free & Pro** Free includes real-time analysis (RTA), sound level metering (SPL), and audio file analysis. Pro unlocks unlimited-duration measurement, advanced modules, and PDF/CSV/JSON report export. Pro includes a 7-day free trial. Supports 17 languages. Reports export independently of the app's display language. Measurement accuracy depends on your device's microphone and calibration; for legal metrology, use equipment certified to the relevant national standard.

Ratings & Reviews

  • This app has not received enough ratings or reviews to display an overview.

This update focuses on professional PDF reports. • Unified section headers and numbering across every report type for a cleaner, more consistent layout. • Redesigned table of contents with precise visual alignment. • Report-integrity hash and QR code on SPL and file-analysis reports, so results are verifiable and traceable. • Many accuracy and wording refinements across SPL, RT60, RTA, and file-analysis reports: clearer event/transient figures, stronger uncalibrated-state disclaimers, and consistent labels. • New app icon and refreshed in-app branding. • SPL export fixes: resolved a duplicate share sheet and corrected sheet timing. • Localization and stability refinements.
