There is a much cheaper solution to noise reduction than buying Sony’s Noise Reduction. For $40 get GoldWave which includes a noise reduction filter. (You can try a fully working version for free for a long time before you have to pay the $40.) I have not used Sony’s and I would hope that at many times the price it is better. Note that GoldWave can stand as a good substitute for both SoundForge and the Noise Reduction package. As for any of these efforts, it often takes many passes reducing just a little the background noise to get to a place you want to be. None of these filters substitutes for getting good sound to begin with.
To stay within Vegas, you have to go the expensive route. However, Vegas will recognize GoldWave and you can (under options I think) designate it as your primary sound editor. Then it works exactly like SoundForge. Right click on an audio clip and you can copy it into Goldwave, then save it back to Vegas once you’ve doctored the clip. So in this sense it does work “within” Vegas.
