Description

From the listing uploaded by “bigballsports”.

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. Usage: 1. Click on the "microphone" icon to start recording of audio. 2. Click on the "settings" icon to switch between time analysis and frequency analysis. Versioning: - https://github.com/nghianja/AudioVisualizer Reference Guide: - Pro Android Media by Shawn Van Every
