Easy Audio Spectrogram vs Live Spectrum Analyzer

Easy Audio Spectrogram is a simple real-time audio visualizer for microphone input. It shows live spectrogram and frequency spectrum views, helping you explore voices, instruments, music, room noise, and everyday sounds. The app is built around readability. Instead of adjusting gain values in the blind or fight a fixed color range, Easy Audio Spectrogram lets you adjust the graph’s dynamic range in real time. Use the live spectrum display as a guide, drag the color scale to the range you care about, and instantly get a clearer spectrogram. For music and voice, the app includes a note-based frequency scale and real-time pitch detection, making it easier to see sung notes, instrument pitch, harmonics, and resonance as they happen. The interface is minimal and comfortable to use in any orientation, even upside down. Text and icons rotate, but controls stay where they are, so the app remains easy to use whether the phone is in your hand, on a table, or pointed toward a sound source. You do not have to understand what's an FFT to use this app, the default setting works well and engineering settings have been translated to understandable concepts. You can save clean spectrogram screenshots directly from the app, without the buttons covering the image and without pressing hardware button combinations. This app is free to use, free of pop-ups or advertisement banners, use it to explore music or the science of acoustics. Additional Features: -Noise profile removal, hold the button to record a profile, release to activate. -Analyze harmonics in real time with multi-touch. -Psychoacoustic filter to make the graph reflect perceived sound signature rather than flat physical reality. -Optimized performance for many hours of use without heating up your device or draining the battery.

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.
