Hi Phil,
Thanks - nice bit of work. Downloaded it this evening and it worked fine here. Will have to download the source and the SharpDSP, Audio, etc and SharpDevelop and see how to built it and play with it. Will have to play some more with it and hook it up with a 96 khz sound card and see how wider band tuning works.
One buglet -- when closing it (via the X button in the title bar) it says Stopping Audio and then hangs. Was using ASIO4ALL setup for a Sountblaster Extigy. About box says version is 10112005A.
Cheers,
Bill (kd5tfd)
