Because most hum noise is in the 50Hz to 60Hz frequency range band, sometimes the simple mode of selecting a specific frequency range band is all that is required to remove the hum noise.
In Simple Mode, do this:
1. | Select a frequency band from the list as follows: |
• | Remove 50Hz: select this option to remove all audio that is in the 50Hz frequency range band. |
• | Remove 50Hz and the harmonics: select this option to remove all audio that is in the 50Hz frequency range band. This option will also remove any corresponding harmonics. |
• | Remove 60Hz: select this option to remove all audio that is in the 60Hz frequency range band. |
• | Remove 60Hz and the harmonics: select this option to remove all audio that is in the 60Hz frequency range band. This option will also remove any corresponding harmonics. |
2. | Use the Reduction level slider to set the amount of attenuation applied on the hum noise. |
3. | 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. |
4. | Click Apply to repair the audio. |
