BMA Spectrum Analyzer vs Spectrum

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.

Spectrum turns your phone into a modern real-time audio analyzer - the clean, fast tool that older spectrum apps never gave you. See sound the moment it happens: a live FFT frequency spectrum and a scrolling spectrogram (waterfall), with automatic peak detection and the matching musical note. Built for a phone screen, with a beautiful dark and light theme - not a cramped desktop port. WHY SPECTRUM • Modern, readable interface - designed for touch, dark & light themes • Save your measurements and revisit them anytime (most analyzers forget everything the moment you close them) • Export the spectrogram as a high-resolution image, or your data as CSV • Works on both iPhone and iPad • Real peak frequency + musical note readout, in cents FEATURES • Real-time FFT spectrum, log or linear frequency axis • Spectrogram (waterfall) view • Tap the chart for a frequency cursor with dB and musical note • Peak hold and peak-frequency tracking • Musical note detection (A4 = 440 Hz) • A-weighting for perceived loudness • Adjustable FFT size (2048 / 4096 / 8192) • Save, name and organize measurements • Image & CSV export • 8 languages SPECTRUM PRO - one-time purchase, no subscription • 1/3 octave RTA view with per-band peak hold - the classic real-time analyzer used for live sound and room tuning • Tone generator: sine tones, 20 Hz-20 kHz logarithmic sweep, white & pink noise for testing speakers and room acoustics • Peak list: the strongest peaks with harmonics tagged • Up to 4 frequency markers on the chart • Calibration offset (±20 dB) to match a reference meter • Extra-high resolution 16384 FFT • High-resolution image export and no ads, forever Everything is processed on your device - no audio is ever uploaded. Microphone access is the only permission needed. Perfect for musicians, audio engineers, students, DIY speaker builders, hum & noise hunters, and anyone curious about the sounds around them.
