Live Spectrum Analyzer
Waveform FFT Sonogram
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
View live microphone or audio-file sound as waveform, FFT, sonogram, pitch, VU, frequency peaks, and visual snapshots.
Live Spectrum Analyzer is a real-time audio visualization tool for musicians, students, teachers, sound makers, and anyone who wants to see sound clearly. Use the microphone for live input, or import an audio file from Files to inspect how frequency, amplitude, pitch, and dynamics change over time.
Switch between waveform, FFT, sonogram, spectrum bars, VU meter, pitch, octave bands, peak hold, envelope, waterfall, phase, Lissajous, and XY Scope views. Each mode is designed for quick visual reading while you listen, tune, practice, demonstrate acoustics, compare sounds, or check a recording.
The app also provides practical analysis readouts, including RMS, peak level, decibels, detected pitch, strongest frequency peaks, spectral centroid, zero crossing rate, dynamic range, estimated BPM, beat strength, mel bands, chroma, noise floor, and clipping status. Results are intended as helpful visual references rather than certified measurement data.

• Live microphone waveform and spectrum visualization
• Import audio files for playback and local visual analysis
• Waveform, FFT, sonogram, bars, VU, pitch, waterfall, phase, and scope modes
