Blastking App vs BMA Spectrum Analyzer

BlastKing is a professional audio toolkit for engineers, musicians, audiophiles, and educators. Three powerful tools in one beautifully designed app. TONE GENERATOR • Generate precise frequencies from 20 Hz to 20 kHz • 5 waveforms: Sine, Triangle, Square, Pink Noise, White Noise • Real-time oscilloscope visualization • Smooth rotary knob control with logarithmic frequency sweep • Precise volume slider with mute toggle • Start muted — engage when ready 31-BAND FREQUENCY ANALYZER • Real-time FFT spectrum analysis across 31 ISO standard bands • Full 20 Hz – 20 kHz coverage • Color-coded amplitude display (green → yellow → red) • Touch any band to see real-time dB readings • Start/Stop analysis on demand • Landscape optimized for maximum detail SPL METER (SOUND PRESSURE LEVEL) • Real-time dB readout with seven-segment display • Vertical LED ladder meter with LOW / MID / HIGH zones • A & C weighting filters • Fast & Slow response time • Minimum, Average, and Maximum statistics • One-tap reset PERFECT FOR: • Audio system tuning and calibration • Room acoustics analysis • Speaker and headphone testing • Music production and education • Noise level monitoring • Hearing protection awareness Requires microphone access for Frequency Analyzer and SPL Meter.

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.
