BMA Spectrum Analyzer vs AudioEngineerKit

BMA Spectrum Analyzer turns your iPhone or iPad into a professional real-time audio spectrum analyzer. Built around a precision FFT engine with a retro instrument aesthetic, it delivers instant visual feedback on any sound source - from mixing and mastering to live events and room acoustics. HOW IT WORKS Point the microphone at any audio source and watch the frequency spectrum come alive across the full 31.5 Hz – 20 kHz range. The METER panel tracks AVG, PEAK, CREST and MAX levels with frequency readout in real time. FREE • Real-time spectrum display • 2 band configurations: 7 and 11 bands • 2 visual themes • Live METER with AVG, PEAK, CREST and MAX • Tap-to-read frequency and level PRO - ONE-TIME PURCHASE • Full controls: fall rate, hold time and compression • All 5 band configurations: 7, 11, 14, 21 and 31 bands • All 11 visual themes • Peak hold display, brightness mode and linear scale • Spectral envelope (ENV) average curve overlay • FFT resolution selector • High-precision dual 4096-point FFT for low frequencies • SPL calibration offset for live sound measurement SPL CALIBRATION Installing sound for a live event or venue? Calibrate against a reference SPL meter and the app displays calibrated dB SPL readings in the METER panel - useful for system checks, venue tuning and compliance measurements. DESIGNED FOR Musicians - Audio Engineers - Live Sound Technicians - Studio Producers - Educators - Audiophiles PRIVACY All audio processing runs entirely on-device. Microphone audio is never stored or transmitted. No account required.

SPL Meter & RTA is a precision measurement toolkit built for sound engineers working on site. Free • Real-time SPL (sound pressure level) meter — A/C weighting, dB • 31-band RTA (real-time analyzer) — ISO 266 standard center frequencies • Microphone calibration • Room Mode Calculator • Feedback detector (new) — spots acoustic feedback live and suggests the frequency and GEQ band to cut (for reference only; the first 3 detections of each session show the frequency) Unlock Pro (one-time purchase) • LUFS loudness meter (BS.1770-4, Integrated/Short-term, target LU delta) • RT60 reverberation time analysis • Delay Finder — ESS sweep-based speaker alignment distance/time • Polarity Checker — passive & active modes, A/B speaker comparison • THD+N Analyzer • Loopback Test — pink-noise RTA-style report • External microphone support • SPL threshold alerts & measurement history (session log) • Dashboard view (SPL + RTA at a glance) • Feedback sound check — collect the frequencies that ring before the show, save them by venue and share (for reference only) A universal app for iPhone, iPad, and Mac. Runs entirely on-device with no internet connection required — no accounts, no ads, no analytics, so your privacy stays yours.
