See the Full Frequency Picture
Every sound contains a rich mixture of frequencies. The spectrum analyzer reveals them all—from fundamental tones to harmonic overtones—helping you understand timbre, diagnose resonances, and explore the acoustic fingerprint of any instrument or voice.
In the app
Here are some things that are even better in the app.
-
Named peaks
Stable partials labeled with note, frequency, and cents.
-
Higher sensitivity
Faster response and higher resolution.
-
Better form factor
Improved portability, performance, and diagram quality.
The Full Experience
What the spectrum reveals
Pitch tells you which note. The spectrum tells you everything else about the sound: the overtones, the room, and the frequencies you did not mean to make.
Tilted so music looks like music
Raw spectra sag toward the top end until the high octaves look empty. A 3 dB per octave tilt puts brightness back where your ear expects it.
Close partials stay apart
A large transform separates overtones only a few hertz apart, and averaging across frames holds the trace steady enough to read.
Rumble and air on one screen
10 Hz to 20 kHz on a logarithmic sweep, so every octave gets equal width instead of everything crowding to the left.
