## What is BMA Spectrum Analyzer?

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
