About this app

This app uses a Fast Fourier Transform (FFT) to analyse the sound picked up by the device's microphone in real time.

It then displays the results in the form of a spectrogram. Try whistling some notes to see the effect.

Also featuring a frequency and musical note detector, displayed at the top left of the screen.

Hello, tell your friends, but i need an app that displays video in real time and returns the source of the incoming sound and light, and can emit different sounds and lights itself.

Excellent app for analysis of audio whether it's music or sounds in a shop it would be better if it allowed you to change the colors for different locations.

Audio quality isn't great and refresh rate is slow and it picks up multiple freqs when I whistle one tone Edit: good to know you're still working on it!
