Yesterday I started getting a hiss in SF Pro 11. The waveform shows a squared off pattern during speech, but nothing when there is no sound. I don't think it's a microphone problem because it doesn't happen in other audio input programs (MixCraft, Vegas Pro, etc.). Volume levels are ok.

I can eliminate the hiss using the filters.

I've been using the program for months without any problems, but I guess I hit something I shouldn't have, and I'm not sure where to even start looking. Any ideas?

Thanx!!

Can you post a short clip of the audio so we have more to go on?
Are there any effects plug-ins or other processors engaged? Excessive comp/limiting and/or RMS normalizing can 'bring out' back ground noise. Remove or disable all the plug-ins from the chainer.. unlike earlier SF versions they will be active if not disabled or removed.

Or a sample-rate mis-match somewhere.
