This app is an online audio tuner to find the pitch of an audio signal. It's handy for musicians and DJs who want to experiment with music on their own, and for students studying an acoustic analysis class.

The app features a microphone to capture sound from anywhere. After that, you will be able to ascertain the exact pitch by measuring the sample rate and using a divider to convert the frequency.

The data is displayed in a graph where the x-axis represents frequency while the y-axis is for amplitude. The app also supports a real-time zoom function, so you can measure small and large frequencies on the same graph.

The app has a sound spectrum analyzer to help you understand what you hear and visualize the pitch.
