Spectrum Lab vs NAMILIUM

A real-time audio spectrum analyzer with a fast, responsive display. Monitor live frequencies from any input source, including built-in microphones, USB devices, and Bluetooth audio. Peak detection helps you track signal changes instantly and see how your signal evolves over time. Use it to analyze music, inspect mixes, and understand the frequency balance of tracks in real time. Check how different environments affect sound, identify noise or unwanted frequencies, and get a clear view of what your microphone is actually capturing. Test speakers, headphones, and audio equipment to see how they respond across the frequency range. Useful for quick checks, setup validation, and comparing different devices or signal paths. Also helpful during development and debugging - visualize audio output, verify signal presence, and monitor changes instantly without needing complex tools. Designed to be simple and direct: no manual configuration, no unnecessary controls. Just open the app, select your input, and start analyzing. No setup required. Everything runs automatically.

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
