For example, turning the Noise Tuner knob all the way to the left (counter-clockwise), means setting a very low threshold value. With a very low threshold value, all audio content with an amplitude above this threshold is considered to be part of the desired audio signal that we wish to preserve. On the other hand, setting a higher threshold value with the Noise Tuner means that any of the audio content with an amplitude lower than the threshold level will be eliminated. Another important concept related to the Noise Tuner knob and the idea of a threshold level is that of a "noise profile". If the threshold determines the level at which some audio content is desired signal and some is noise, think of the noise profile as the "shape" of the point where the desired signal meets the noise. SoundSoap has the ability to use either a "flat" noise profile, in which all frequencies are treated equally ­ or, if the Learn Noise feature is used, then a custom noise profile is created that addresses the actual broadband frequencies that happen to be present in a media file. When using a learned noise profile, more noise reduction is applied in the frequency ranges where it is needed. The Noise Tuner can be used in a variety of ways ­ first, it can be set automatically by first using SoundSoap's Learn Noise feature. This method is ideal when the media file being cleaned has an isolated area of the noise by itself. Learn Noise first analyzes the frequency content of this portion of audio, creates a noise profile, and then automatically sets the Noise Tuner knob to what should be an ideal position. The diagram below illustrates this concept. audio above threshold = desired signal THRESHO LD LEVEL/NO ISE PROFILE Amplitude If we needed to adjust the threshold level, we could just rotate the Noise Tuner knob ­ for example, if we rotated it counter-clockwise, the noise profile would remain unchanged, but more of the overall audio content would be considered to be the part we wish to preserve. Amplitude audio above threshold = desired signal TH RESHO LD LEVEL/NO ISE PROFILE audio below threshold = noise Frequency This diagram illustrates having a low Noise Tuner setting, with a custom noise profile ­ a custom noise profile is the result of having used the Learn Noise feature ­ different frequencies are affected in different ways. The second way to use the Noise Tuner is to make adjustments without having first "learned" a custom noise profile. This method is typically used when the media file being cleaned does not contain an isolated portion of noise by itself. In some instances, learning a noise profile within a section of the desired audio signal can cause some frequencies that should be preserved to be removed, based on the custom noise profile that's created. In cases where there is no isolated portion of noise by itself, adjusting the Noise Tuner knob using a "flat" noise profile can often produce better noise reduction results, as a flat noise profile affects all frequencies equally. The diagrams below illustrate using a flat noise profile. audio below threshold = noise Frequency This diagram illustrates having a high Noise Tuner setting, with a custom noise profile ­ a custom noise profile is the result of having used the Learn Noise feature ­ different frequencies are affected in different ways. 30 SoundSoap User's Guide audio above threshold = desired signal THRESHOLD LEVEL/NOISE PROFILE Amplitude audio below threshold = noise (or most of what you hear) is noise. When you find the best setting for the Noise Tuner in Noise Only mode, (the one that allows you to hear the most noise) you should hear a dramatic difference when you toggle the listening mode back to the "On" position. When Noise Only mode is used, the Wash Window works "in reverse" ­ that is, the left side still shows both red and blue lines, but when the ideal noise reduction settings are found, only red lines (noise) are displayed on the right side. Noise Reduction Knob Frequency This diagram illustrates having a high Noise Tuner setting, with a flat noise profile ­ in this example, all frequencies are affected equally. 3 Whether you're using a learned noise profile or a flat noise profile, the Noise Tuner knob behaves in exactly the same way ­ it simply varies the threshold level. So, with a flat noise profile, if we were to rotate the Noise Tuner knob counter-clockwise it would lower the threshold level, just as in the previous example using a learned noise profile. To make a setting with the Noise Reduction knob, click the knob with your mouse, and rotate to the left or right. [. . . ] In iMovie, locate the clip that needs editing. 46 SoundSoap User's Guide 4.
