WHAT NAMILIUM IS A real-time audio analyzer for measuring sound, seeing it, and singing with it. Spectrum, spectrogram, oscilloscope, loudness metering, and now a voice tuner, with no extra purchase. FFT sizes up to 32768 (about 1.5 Hz resolution). No account, no ads, no tracking. WHO IT IS FOR - You want your stream or podcast to sit at the right level - You want to check how a room or a speaker actually sounds, in numbers - You want to see whether you are singing in tune, not just hear it - You want to keep the tune you just hummed as written notes - You want to watch how sound works while you learn it GETTING STARTED Open the app, turn on the mic, and whatever is around you is drawn as it happens. Load an audio file to watch a track you like. Play a sine tone or a sweep from the signal generator to check gear or a speaker. Switching views and adjusting the details both live in the control panel. WHAT YOU CAN DO Measure - Spectrum: A and C weighting curves, 1/1 to 1/12 octave band bars, or a continuous curve. You can load a correction curve for a measurement mic (FRD format) - Loudness: BS.1770 LUFS (momentary, short-term, integrated), loudness range, and true peak with 4x oversampling, useful for matching levels for streaming or podcasts - dB SPL: pair a measurement mic with its correction curve to read sound pressure levels - Snapshots and CSV: keep the current shape to compare against, or export the numbers to work on elsewhere - Multi-resolution analysis: fast response up high, fine detail down low See - Spectrogram: how frequencies move over time. Pinch to zoom in time or frequency, and freezing recomputes the visible range. The axis can be linear, logarithmic or mel, and you can overlay the three peaks that shape a vowel sound - Waterfall: your spectrum history as a 3D landscape - Oscilloscope: Auto and Normal triggering holds the waveform still, with a ms/div time base you can pinch to zoom - Phase Scope: stereo width and phase on a Lissajous display, with a correlation meter for mono compatibility - Crosshair readout: exact frequency, time and level under your finger Sing - Voice tuner: sing and your pitch flows across the screen as a line, with the note you are on spelled out. Set a target note and you can see whether you are on it, close to it, or off - Transcription: what you sing is written down as notes. Export as MIDI and the tune you just hummed goes straight into your DAW. The audio and the raw numbers come along too - Click and beat: keep time while you sing and the exported notes line up to the bar. Freeze the display and zoom in to find where it drifted Input and output - Input: the built-in mic, a Bluetooth mic, or your own audio files - Signal generator: sine tones and sweeps for testing - Screen capture: save or share any analyzer view as an image WHAT MAKES IT DIFFERENT - It works entirely on your device. Your audio is never sent anywhere - Nine themes including Neon and Ocean, plus custom themes you design yourself, and an optional rainbow that flows across the frequency axis

Spectrum turns your phone into a modern real-time audio analyzer - the clean, fast tool that older spectrum apps never gave you. See sound the moment it happens: a live FFT frequency spectrum and a scrolling spectrogram (waterfall), with automatic peak detection and the matching musical note. Built for a phone screen, with a beautiful dark and light theme - not a cramped desktop port. WHY SPECTRUM • Modern, readable interface - designed for touch, dark & light themes • Save your measurements and revisit them anytime (most analyzers forget everything the moment you close them) • Export the spectrogram as a high-resolution image, or your data as CSV • Works on both iPhone and iPad • Real peak frequency + musical note readout, in cents FEATURES • Real-time FFT spectrum, log or linear frequency axis • Spectrogram (waterfall) view • Tap the chart for a frequency cursor with dB and musical note • Peak hold and peak-frequency tracking • Musical note detection (A4 = 440 Hz) • A-weighting for perceived loudness • Adjustable FFT size (2048 / 4096 / 8192) • Save, name and organize measurements • Image & CSV export • 8 languages SPECTRUM PRO - one-time purchase, no subscription • 1/3 octave RTA view with per-band peak hold - the classic real-time analyzer used for live sound and room tuning • Tone generator: sine tones, 20 Hz-20 kHz logarithmic sweep, white & pink noise for testing speakers and room acoustics • Peak list: the strongest peaks with harmonics tagged • Up to 4 frequency markers on the chart • Calibration offset (±20 dB) to match a reference meter • Extra-high resolution 16384 FFT • High-resolution image export and no ads, forever Everything is processed on your device - no audio is ever uploaded. Microphone access is the only permission needed. Perfect for musicians, audio engineers, students, DIY speaker builders, hum & noise hunters, and anyone curious about the sounds around them.

Verdict
The clearest difference is in-app purchases: NAMILIUM at none against Spectrum's 1. NAMILIUM also leads on ads (none vs shown). Spectrum's advantage is iOS requirement (15.0 vs 17.0). On price, update cadence and device support there is nothing between them.
