BMA Spectrum Analyzer vs Morlet

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.

Morlet shows the sound around you as a live, scrolling picture of frequency over time. Sing, play, whistle or just listen to a room, and watch notes, harmonics, rhythm and noise appear as they happen. TWO WAYS TO SEE SOUND • Spectrum: a fast Fourier transform with up to 288 rows and 8,192-sample frequency detail, on a log or linear axis. • Wavelet: a continuous Morlet scalogram with up to 48 scales per octave, giving low notes precise pitch and high sounds precise timing. Mexican Hat, Haar and Daubechies 8 wavelets are included too. OPEN ANY AUDIO • Play songs, voice memos and recordings from Files, or share audio to Morlet from other apps, with the graph scrolling in sync and a slider to jump around. READ ANY MOMENT • Tap or drag on the graph to read the frequency, nearest note with cents, level and time at that point. • Freeze the picture to study a moment while the microphone keeps running. • A pitch line traces the note across the graph with markers at its harmonics, and the tuner shows the note and cents. • A spectrum curve above the graph shows the current spectrum with averaging and peak hold, or octave and third-octave bars. • Save any view as an image to share. TUNE IT TO WHAT YOU HEAR • One-tap setups for music and singing, speech, drums, hum and machinery, and birdsong. • Set the lowest and highest frequency to put every row where you need it. • Choose the window shape and A or C frequency weighting, and generate sine, triangle, square and sawtooth tones or a full-range sweep. • Adjust frequency detail, time overlap, brightness and contrast. MAKE IT YOURS • A lab-notebook design in ink on white, or matte black for night use. • Choose your accent color and graph colors, including Ink, Sepia, Inferno, Grayscale and fully custom colors. • A built-in guide explains what each setting is for. RECORD AND EXPORT • Record sessions and share them as uncompressed WAV audio, CSV analysis data in decibels, and JSON metadata describing the settings used. • Recordings stay on your device until you share them. ON IPAD • A larger graph with every analysis setting open beside it, in portrait or landscape. PRIVATE BY DESIGN Morlet has no accounts, ads, tracking or in-app purchases, and collects no data. Audio is analyzed on your device and never leaves it unless you share a recording. Good for musicians, singers, sound designers, students, teachers, audio engineers, bird lovers, and anyone curious about what they are hearing.
