FFT Analyzer vs Live Spectrum Analyzer

FFT Analyzer is a powerful real-time spectrum analyzer for iPhone. It visualizes audio signals as a detailed frequency spectrum and waveform while presenting important measurements clearly. In addition to live microphone analysis, you can import and examine audio and video files from the Files app or Photo Library. Control playback directly from the waveform while the spectrum and measurements are recalculated for the current position. Key features: - Real-time FFT analysis using the microphone - Analysis of local audio and video files - Import from Files and Photo Library - Open compatible media directly from other apps - Interactive waveform with position slider - Play, pause, stop, and skip controls - Peak, RMS, and clipping indicators - Detection of dominant frequencies - Adjustable frequency and decibel ranges - Linear, logarithmic, and octave-based frequency axes - FFT bars, spectrum trace, and combined display - Waterfall and oscilloscope displays - Persistence, peak hold, and other visual effects - Customizable landscape layout - Extensive smoothing and level behavior settings - User interface in 18 languages File analysis also provides information such as duration, sample rate, channel count, peak values, and prominent frequency regions. Analysis remains synchronized with playback so you can inspect individual sections precisely. FFT Analyzer is designed for musicians, audio engineers, producers, educators, students, and anyone who wants to visualize and better understand audio signals. Processing takes place directly on your iPhone for fast and independent audio analysis tailored to the current signal. Export and reports Analysis results can be exported as a CSV file. The export includes the app version and a timestamp, file details and metadata, technical audio data, overall RMS, peak, and dynamic range values, dominant frequencies, detected findings, and time-based RMS, peak, and frequency values for each analysis frame.

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.
