Noise Reduction Compression Brightness Ambience Minimum Level Decay Noise Reduction Hum Frequency
The Highpass effect removes frequencies below the specified Cutoff frequency. Use it to reduce low-pitched noises and rumbles.
The Lowpass effect eliminates frequencies above the specified Cutoff frequency. Use it to eliminate high-pitched noises, squeals, and whistles.
Invert
The Invert effect inverts the phase of all channels. Use it, for example, to bring the sound of one shot of an event into phase with another shot of the same event taken from another camcorder.
NewBlue Audio Polish
Audio Polish that cleans and enhances audio. It includes features for noise reduction, compression, brightening the high end and even adding reverberation.
Sets the amount of noise reduction to apply to the audio. Rotate the knob to the right to decrease background noise.
Boosts lower-level signals, flattening the sound to be more consistent. Compression is especially useful for dialog because it brings voices up to a constant level. Rotate the knob to the right to increase compression.
Adds a little high end to the signal. Rotate the knob to the right to “brighten” the sound. Brightening help polish muddy recordings.
Adds a little reverberation to the mix. Rotate the knob to the right to increase the amount of reverberation.
NewBlue Auto Mute
Auto Mute reduces background noise by turning off all sound when the signal goes below a specified threshold.
Sets the minimum acceptable signal level. Auto Mute only allows sounds above the minimum level to play. Auto Mute erases the sound whenever it dips below the minimum level. Turn the knob to the far left and almost every sound level makes it through. Turn it to the right and sensitivity increases to the point that only the loudest sounds make it through.
Controls the speed at which a sound is removed after its level drops below the minimum threshold. Most sounds have a natural decay to them. A quick cut immediately after the decay drops below the minimum Level sounds unnatural. On the other hand, the longer the decay, the more background noise can be heard. Turn the Decay knob to the left for a quick fadeout. Turn the knob to the right for a longer decay.
NewBlue Cleaner
Removes many undesirable sounds from the mix. The effect includes noise-reduction circuitry and tone elimination, useful for removing isolated tones such as hum.
Sets the amount of noise reduction to apply to the audio. Turn the knob to the right to decrease background noise.
Sets the cut frequency for the tone eliminator. If you know the frequency (such as 60-Hz electric hum), select it. If you don't know the frequency, perform the following steps:
1. Turn the Hum Cut slider to the far left so that it magnifies the tone.
2. Turn Hum Frequency control to find the spot where the tone that you want to remove is at its loudest. After you have isolated the frequency, turn the Hum Cut control to the right to set the depth of the tone elimination.
Most tones are not pure; they have overtones, or harmonics. Turn the Hum Harmonics slider to the right to add tone removal of higher harmonics. Don't overdo it because the increased filtering can also cut desired sounds.

NewBlue Hum Remover
Hum Remover scrubs hum from your soundtrack. Electric power is usually the most common reason for hum. Reasons range from a microphone cable that runs too close to a power cord to the humming sound of an electronically dimmed light. Power hum is easy to isolate because it is always the same frequency: In North America, the power frequency is 60-Hz. In other countries, power hum is 50-Hz.Hum Remover applies a
notch filter specifically to the frequency of the hum. Sometimes, that's not enough. The hum signal often distorts, which adds additional tones. Hum Remover calculates the frequencies of these additional tones and removes them as well.
Sets the frequency that must be removed. Typically, the frequency is 60-Hz or 50-Hz. However, you can turn the knob to select any frequency within the range of 40-Hz to 75-Hz. The two most useful frequencies, 50-Hz and 60-Hz, are provided as presets.
Determines the strength of the hum filter. Start with the knob at the left and turn to the right until the hum goes away. Ensure that you have set the Pitch and Hum Distortion sliders correctly. If the Pitch and Hum Distortion sliders have not been set appropriately, Hum Remover removes the wrong part of the signal.
Provides information to the Hum Remover about the level of distortion of the hum tone. A distorted hum has higher frequency overtones that must also be eliminated. Turn the knob to the right to remove more of these overtones (also known as "harmonics"). The number of overtones removed depends on the level of distortion.
NewBlue Noise Fader
Reduces background noise by progressively reducing the volume of quieter sounds.
Sets the signal level for attenuation. Noise Fader leaves any sound louder than the threshold unchanged, while fading down sounds below the threshold. Turn the knob to the left to set the threshold low. Turn the knob to the far right to fade all but the loudest sounds.
Determines how to fade out sounds below the threshold level. Turn the knob to the left for minimum fading. Turn the knob all the way to the right to completely mute all sounds below the threshold. The correct level is somewhere in the middle.
NewBlue Noise Reducer
Removes background noise. Use the effect to clean videos shot under less-than-ideal audio conditions.
Sets the intensity of the noise reduction. Turn all the way to the left for no reduction at all. Turn to the middle to significantly drop background noise while keeping the louder sounds prominently in the foreground. Turn further to the right and more of the signal fades out.
Notch
The Notch effect removes frequencies that are near the specified center. The Center control specifies the frequency to be removed. If you are removing power-line hum, type a value that matches the power-line frequency used by the electrical system where the clip was recorded. For example, in North America and Japan, type 60 Hz, and in most other countries, type 50 Hz.
PitchShifter (Windows only)
The PitchShifter effect adjusts the pitch of the incoming signal. Use this effect to deepen high voices or vice versa. You can adjust each property by using graphical controls in the Custom Setup view, or by changing the Individual Parameters values.
FineTune Formant Preserve PreDelay Absorption Size Density Lo Damp Hi Damp Mix Note:
Fine tunes the semitone grid.
Prevents formants in the audio clip from being affected. For example, use this control when increasing the pitch of a high voice to prevent it from sounding cartoon like.
