Spek Spectrogram analyzer vs NAMILIUM

Professional audio spectrum analysis and spectrogram visualization for engineers, producers, creators, and audio enthusiasts. Spek transforms audio into a detailed visual spectrogram, allowing you to inspect frequencies, identify compression artifacts, evaluate audio quality, and explore how sound changes over time. Whether you're mastering music, verifying lossless audio, analyzing recordings, or troubleshooting noise issues, Spek provides powerful analysis tools directly on your device. Built with performance and privacy in mind, all audio processing is performed locally on your device. No audio files are uploaded, and no analysis data leaves your device. PROFESSIONAL AUDIO ANALYSIS Import audio files and instantly generate detailed spectrograms that reveal the frequency content of your recordings over time. Use Spek to: • Verify audio quality and detect compression artifacts • Identify frequency cutoffs caused by lossy encoding • Check whether a file is truly lossless or an upscaled source • Analyze background noise and unwanted frequencies • Inspect dynamic range and spectral balance • Examine left and right audio channels independently • Explore detailed frequency information throughout an entire recording SUPPORTED AUDIO FORMATS Analyze a wide range of popular audio formats, including: • WAV • AIFF • MP3 • AAC • M4A • FLAC • OGG Advanced decoding and file validation help ensure reliable analysis, even when audio files contain metadata issues or damaged container structures. HIGH-RESOLUTION SPECTROGRAMS Customize the analysis engine to match your workflow: • Multiple FFT sizes (1024, 2048, 4096, 8192) • Adjustable overlap and time density settings • Selectable window functions including Rectangular, Hann, and Hamming • Configurable minimum and maximum dB ranges • Multiple color palettes for enhanced visibility Fine-tune the balance between frequency resolution and time resolution to reveal exactly the information you need. Navigate large spectrograms with ease: • Pinch to zoom • Smooth pan navigation • Linear frequency scale • Logarithmic frequency scale • High-detail deep zoom rendering • Fast viewport updates and responsive interaction Explore both broad frequency trends and microscopic spectral details without sacrificing performance. Listen while you analyze. Spek includes an integrated audio player with a synchronized playhead that moves across the spectrogram in real time. Quickly correlate what you hear with what you see and locate specific events within the audio. Features include: • Real-time playback synchronization • Moving visual playhead cursor • Optional playhead following mode • Efficient rendering for smooth performance Visualize incoming audio directly from your microphone. Monitor environmental sounds, voices, instruments, and test signals in real time through a continuously updating spectrogram display. Ideal for: • Acoustic inspection • Noise identification • Equipment testing • Educational demonstrations • Sound design experimentation Share or archive your analysis results with high-resolution spectrogram exports. Export: • Full spectrograms • Current viewport selections • Professional-quality PNG images Perfect for reports, documentation, presentations, and collaboration. Spek is useful for: • Audio Engineers • Music Producers • Mastering Engineers • Podcasters • Sound Designers • Archivists • Collectors • Researchers • Students and Educators Whether you're validating audio sources, investigating recordings, or studying sound behavior, Spek provides the tools needed for accurate visual audio analysis. FAST, PRIVATE, AND OFFLINE Your privacy matters. • No account required • No audio uploads • No cloud processing • No user tracking by the app itself • 100% local audio analysis Audio decoding, FFT processing, and spectrogram rendering are performed directly on your device, giving you complete control over your files and data.

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
