Sound Analyzer vs Live Spectrum Analyzer

Sound Analyzer analyzes audio from your microphone in real time using FFT, and displays the frequency spectrum visually. Perfect for noise surveys, acoustic checks, and environmental measurements. 【Features】 ■ Real-Time Spectrum Display Live FFT analysis from the microphone. Simultaneously shows peak frequency, peak amplitude, and RMS level. ■ Audio Recording & Playback (Pro) Record audio while measuring. During playback, the original FFT spectrum is recalculated in real time. Linear scale display is also supported. ■ GPS Location Tagging (Pro) Automatically attach location data to recordings and measurements. View where each measurement was taken on a map. ■ Memo & Tag Management (Pro) Add memos and tags to each recording for easy organization. Categorize by factory, traffic noise, outdoor, and more. ■ CSV Export (Pro) Export measurement data as CSV files for use in Excel or Numbers — ideal for reports and analysis. ■ Playback Speed Control (Pro) Play recordings at 0.5x, 1x, 2x, or 4x speed to closely examine audio details. 【Use Cases】 · Construction and facility noise level monitoring · Frequency response checks for instruments and speakers · Acoustic recording at outdoor events and natural environments · Audio and music education and research Professional frequency analysis, made simple — anytime, anywhere.

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. Key features: • 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 • Adjustable gain, time window, FFT floor, sonogram brightness, contrast, and speed • Pitch reference, tolerance, microphone gain, and noise gate settings • Record audio locally, review saved recordings, and share or delete files • Capture visualization snapshots as PNG images • Local-first workflow with no account required Subscription and purchase information: The app offers a free experience and optional Pro access. Actual prices, trials, promotions, and availability are shown in the App Store. Privacy and data information: Your microphone input, imported audio, recordings, snapshots, and analysis results stay on your device by default. The app does not require an account and does not upload your media to a server operated by us.
