Om du har Wavelab 6 så skulle jag prova spektrum editorn:
” SURGICAL EDITING
Together, these two modes make quick work of cleaning up audio. The Spectrum option is particularly useful because it shows things that may not be visible in any other view and the editor allows for surgical removal. For example, low rumble due to air conditioning is usually visible as a line running through the Spectrum view. Using the Spectrum selector, you can select a portion of that line that appears in a quiet passage and extend that selection throughout the audio file.
Using the editor, the selected noise can be “damped” or filtered out with a linear phase filter whose slope is variable up to a steep 96 dB/octave, or can be set to “infinite,” which Steinberg says gives a slope in excess of 1,000 dB/octave. The selection can also be faded out and back in for a more subtle approach. By adjusting the crossfade time, WaveLab smooths out the areas where the filtered audio meets the unfiltered. The results are every bit as good as I get using a broadband noise-reduction plug, but without the artifacts.” *
