From the developer:
If a picture speaks a thousand words, then a video certainly adds a good few more on top of that. Watch the presentation video at our website. There you can also find Radio Recorder User Manual.
Stream it. Record it. Keep it.
"Radio Recorder is the most powerful streaming audio capture toolkit ever created!"
