Simple Mode

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.
