MelSpectrum - Audio Analyzer on Windows Pc

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.

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.

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.

Trust and transparency
MelSpectrum uses microphone access for real-time audio capture. The app includes ads in the free experience, and some advanced features are available through Premium or temporary rewarded unlock access. Internet and billing access support monetization features, while the core experience centers on microphone-based analysis.
