    public abstract class DspActivity
extends Activity
    A DSP activity is one that allows to show and control a DSP process. It can be used to either run a "live" process and use the DSP facilities as an example or to run tests and display tests results on the screen. A DSP thread is launched to control the process of acquiring, modifying and outputting audio signals, with help from the algorithm classes. This activity also has a companion thread called the SystemWatchThread which takes care of polling the system for CPU usage and pinging this activity so the screen gets updated periodically.
