I have battled with Sound Forge 7 and Noise Reduction 2 for the past 2 hours and cannot remove background noise without bizarre chirps at various locations throughout the clip. I I have been through the Vegas 5 Editing Workbook and followed the tips to the letter. I went online and reviewed troubleshooting and FAQs and followed their instruction...nothing. Every time I hit OK, the chirps pop up. I have tried sliders...I am at a loss. I know I am doing something wrong, but what? Any help would be appreciated.
