SciChart Android ships with ~90 Android Chart Examples which you can browse, play with, view the source-code and even export each SciChart Android Chart Example to a stand-alone Android Studio project. All of this is possible with the new and improved SciChart Android Examples Suite, which ships as part of our Android Charts SDK.

The Audio analyzer demo showcases how to use SciChart Android charts in a scientific context.

Download the examples and enable your microphone to see this demo at work.

In this example we listen to the microphone on your Android device or embedded systems and create a waveform of the sound recorded in the top chart. This chart has 500,000 data-points drawn in real-time on our High Performance charts. The example application then performs a Fourier Transform, creating a spectral / frequency analysis of the audio waveform and plots in the lower left chart. Finally, the histogram of the Fourier transform, known as a spectrogram, is plotted in a SciChart Android Heatmap control in the bottom right of the example.

If you are creating an app that needs to visualize scientific data from data-acquisition devices, audio spectra, or visualize radio frequency or spectral analysis choose SciChart to shortcut your development time & get to market faster with our well-tested, reliable Android Chart library.

The full source code for the Android Audio, Radio frequency and Spectrum Analyzer example is included below (Scroll down!).
