As I recall, back in the day, SoundForge was the lightest and fastest audio editor for Windows. (On the Mac there were of course many choices for simple editing, going all the way back to SoundEdit16.) It was a little sad to SoundForge sold to Sony. The author should be proud of that software. There was nothing else comparable for Windows back then, to my knowledge. Interesting that he became involved with something as different as Bitcoin.
