MicCheck vs Simple Spectrogram

MicCheck helps you quickly test microphones, speakers, AirPods, Bluetooth headsets, and audio routes from your iPhone. Run practical audio checks for everyday problems: weak microphone quality, noisy recordings, incorrect left/right channels, Bluetooth headset issues, and speaker response problems. Core features: • Left and right stereo speaker test • Balance tone test • 5-second microphone recording and playback • Recording quality score with RMS, peak, and spectral centroid analysis • Noise floor measurement for room/background noise • Microphone comparison for iPhone, AirPods, and Bluetooth headsets • Frequency Sweep from 20 Hz to 20 kHz • Test history by device • Shareable and exportable audio reports MicCheck is useful when you want to check whether your AirPods microphone sounds worse than your iPhone microphone, confirm that both stereo channels work correctly, test a Bluetooth headset before a call, or compare audio quality before and after cleaning a microphone grille. MicCheck does not provide medical, hearing, diagnostic, or repair advice. Results are practical audio measurements intended to help users compare devices and identify possible audio quality issues.

See the frequencies in the sound around you. Spectrogram turns your microphone input into a smooth, real-time spectrogram with a clear logarithmic frequency scale and Inferno colors. • Watch sound evolve over time, with the newest audio at the top. • Pause and tap any slice to inspect its frequency spectrum. • Tap or drag on the spectrum to find nearby peaks and their exact frequencies. • See the nearest musical note and the difference in hertz and cents, referenced to A4 = 440 Hz. • Adjust the frequency range, noise floor, and contrast. • Use portrait or landscape on iPhone and iPad. Audio is analyzed on your device in memory. It is never recorded, uploaded, or shared. No account, ads, or tracking. Musical note labels describe individual spectral peaks, which may be harmonics rather than a sound’s fundamental frequency.
