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.
