A TIP 11. Using Waves X-Noise
- Create a noise profile by selecting an audio section from the source
recording (at least 100 ms) containing just the noise that you want to
remove. Click the Learn button in the Noise Profile area below the X-Noise
Analyzer. The button blinks and displays Learning. Play this section through
X-Noise. Click the Learn button again to stop the learning process and
create the noise profile, which appears as a white line on the X-Noise
Analyzer. The line represents the frequency content of the analyzed noise.
At this point, save your X-Noise setup, which includes your noise profile.
If you cannot find a noise-only section, try the default white noise profile
or one of the other available factory presets. After creating the noise
profile, cancel the selection of the noise-only segment to operate on
the whole sound file. While playing the recording, adjust the Threshold
and Reduction controls to the desired amount of noise reduction. Threshold
sets the level at which the noise profile is used to distinguish between
the sound source and the noise. Setting the Threshold to 10 dB typically
means that the noise level is below the noise profile and therefore subject
to removal. Use the Reduction control to set the amount of noise reduction
applied. Increasing the Reduction setting increases the amount of noise
removed from below the noise profile. If time-aliasing artifacts (singing
or robot-like sounds) appear, decrease the Reduction setting and increase
the Threshold (about 30 dB above the background noise). Artifacts can
be further minimized by adjusting the |
