Frequency Analyzer
Visualize the frequency spectrum of any sound in real-time. See which frequencies are present in your audio using your device's microphone. For measuring sound levels, try our sound level meter.
Frequency Spectrum
Understanding the Spectrum
Bass sounds, rumble, thunder
Human voice, most instruments
Treble, consonants, brightness
Sibilance, air, sparkle
What is a Frequency Analyzer?
A frequency analyzer, also known as a spectrum analyzer, breaks down sound into its component frequencies using Fast Fourier Transform (FFT). This allows you to see which frequencies are present in any audio signal and their relative intensities. Combined with a decibel meter, you can get a complete picture of your sound environment.
Real-Time Analysis
See instant visual feedback as you speak, play music, or analyze any sound in your environment.
