which first: Normalize or Noise Reduction? -Sound Forge - PC

Subject:which first: Normalize or Noise Reduction? Posted by: artistdomain Date:1/16/2003 8:21:01 PM I have a video project done in Premiere consisting of captured clips strung together on Premiere's timeline. Some of the clips have audio volume that's too low and and have background noise such as A/C. The others are loud enough and sound clean. I want to raise the volume and clean up the noisy clips so that they are as loud as the good sounding ones. Should I use Noise Reduction (2.0) on each individual problem clip first and then export the whole program audio AVI to use Sound Forge's (4.5h) Normalize funtion on the whole file? Or Should I Normalize the whole audio AVI and then use Noise Reduction to clean it up. Does the new Sound Forge 6.0 offer enhanced function capability to do any of this? Thanks a million for any advice.

The background noise print would most likley be different. SF-6 comes with the stand alone application Batch Converter-5.0b. It can save lots of time if one has to normalize or process a lot of files.

If not any artifacts caused by the noise reduction (and there always are some with any type of noise reduction) will be amplified also. One way to always find the answer to any audio question: try each way and see what sounds best.
