Real Time Audio on Blackberry

Quite some time ago I was playing around with audio frequency signals analysis on BlackBerry. I came up with a rudimentary audio FFT display. I posted binaries to BlackBerryForums. The other day an other signals analyst and electroncics engineer tracked me down. He had seen my code and was looking advice on getting audio input on BlackBerries for a similar project. So I decided to publish my code, such as it is, under GNU GPL v3 on Google Code.
