MelSpectrum - Audio Analyzer

When a note drifts, a mix turns muddy, or a room rings in the low end, guessing slows you down. MelSpectrum is a real-time audio analyzer for Android that helps you see pitch, tone balance, and frequency detail the moment your phone hears it. 🔒 100% Ad-Free • Pro Precision • Zero Data Collection Enjoy a clean, distraction-free professional tool. The app contains no ads, requires no login, works 100% offline, and collects no personal data. Who it's for For musicians, MelSpectrum shows the dominant note, pitch deviation in cents, and confidence, so you can tune and check intonation while you play. For producers and mix engineers, the Mel spectrogram, tone balance, and spectral tilt make it easier to spot low-end buildup, harsh highs, and unstable transients before they become bigger problems. For acoustics, education, and voice analysis, the high-resolution presets reveal room resonances, speech formants, and changing spectral patterns in a format that is fast to read on mobile. Why people install it • Tune more confidently thanks to note detection with cent deviation. • Read tonal balance faster thanks to low, mid, and high energy breakdown. • See important sounds more clearly thanks to adaptive denoising. • Catch movement and instability thanks to real-time spectral flux and peak hold. • Keep your workflow mobile thanks to on-device analysis and image export. Key features 🎯 Pitch tools • Dominant note detection with a ±50 cent tuning gauge • Confidence display and color-coded tuning feedback • English note names, with French notation support 📊 Spectrogram and analysis • Real-time Mel spectrogram optimized for fast visual reading • FFT presets from 512 to 8192 points for voice, general use, transients, and acoustics • Optional Centroid and Peak overlays for extra visual tracking 🎚 Spectral insight • Tone balance across lows, mids, and highs • Spectral tilt labels from Dark to Neutral to Bright • Spectral flux meter with peak hold for transient activity ⚙ Expert controls • Adjustable smoothing for faster or steadier readings • Display duration options for short events or longer trends • Multiple color palettes, including Inferno and Plasma • JPEG spectrogram export in Premium mode What makes MelSpectrum different This audio analyzer combines note detection, Mel spectrogram viewing, tone balance, spectral tilt, spectral flux, and adaptive denoising in one mobile workflow. Its native DSP pipeline is built for responsive real-time analysis, and the pitch engine is designed to show small tuning deviations in cents instead of only broad note labels. Rather than giving you a single number without context, MelSpectrum helps you understand what your sound is doing across pitch, energy, and movement at the same time. Transparent pricing & privacy MelSpectrum accesses the microphone solely for real-time audio analysis, with no audio recording or data transmission. 100% Ad-Free: Zero ads, zero pop-ups, zero tracking, ever.
