To use the Noise Reduction on audio, do this:
1. | In step 1, do one of the following: |
• | Select the first option and then select a range of the audio that only contains the noise, i.e. devoid of the audio you want to keep in the file. See Range Selection for more information on selecting a range of an audio file. Next, click the Analyze button to analyze the range of audio. Doing this creates a noise profile that CyberLink AudioDirector uses to remove the noise. |

|
Note: you can click the Noise button to listen to the detected noise, if required.
|
• | Select the second option and then Select a preset from the drop-down. Select the preset that best fits the type of noise you are trying to remove. |
2. | Use the Sensitivity and Noise reduction level sliders to adjust the amount of reduction applied to the selected range. If required, click the Noise button again to listen to the noise that will be removed. |

|
Note: when previewing the noise, if you hear portions of the audio you want to keep, it is recommended that you reduce the Sensitivity and/or the Noise reduction level until you don't hear it anymore, for the best results on the repaired audio.
|
3. | Use the Dry-Wet mix slider to set the ratio between the dry (original audio that includes the unwanted noise) and wet (audio with noise reduction applied) audio. Adjusting the mix can balance the original audio and the audio with the noise reduction applied, reducing a loss of quality on the audio portion you want to keep. |
4. | Click the Next button to go to step 2. |
5. | Select which range of audio you want to apply the noise reduction to by selecting one of the following: |
• | Analyzed range only: select this option to only apply the noise reduction to the range of audio you selected and analyzed in step 1. |
• | Entire audio content: select this option if you want to apply the noise reduction to the entire audio clip. |
• | Select a different range: select this option to select a new range of audio where you want the noise reduction applied. This range can contain both the noise and the audio content you want to keep. |
6. | If required, you can preview the repaired audio by selecting Restored result and then clicking the Preview button. Select Original audio if you want to play the original audio. |

|
Note: click the Save as Preset button once you are done to save the Noise Reduction settings as a new preset. The next time you need to remove noise from audio that was recorded in the same or similar environment, you can just select the preset from the drop-down in step 1.
|
7. | Click Apply to repair the audio. |
