Well, for me to write one of those may really be scary, since even though I'm a programmer, I'm not familiar with Java (I have always hated its verbosity). However, the DSP part is what's more scary, since I don't know if there are ready-made DSP functions for Java. Also, if I wanted to really do

As far as best practices go writing HW independent code should be desirable.
