This application is just a reference implementation showcasing the use of the following two open libraries:
– Java translation of fftpack [http://www.netlib.org/fftpack/jfftpack.tgz]
– GraphView [https://github.com/jjoe64/GraphView]
It is by no means an optimized implementation so users should notice the considerable lag in the display. Users are advised to incorporate into their own codes by rewriting it.
1. Click on the “microphone” icon to start recording of audio.
