 | Where are the audio filters?

I am editing some old vhs tapes and this one section has a hum in it. I have read the manual and think the Hum Cut Filter is what I want. Where are the filters located and how do you apply them?

Select your audio clip in the timeline or in the bin and Press "CMD-5" to open the Audio Effects window. There you have various audio filters; to remove a hum you should probably try the EQ section.

NTSC In the Audio Effects I selected 60Hz Cut2
I left Hi and Mid on Notch and set Lo EQ on Hum Cut
the selected audio track turns magenta but I do not hear anything different. the hum is still there.
Any suggestions?

Hi Jerome,
Assuming that the effect is being applied to both the audio channels of the clip, and that "bypass" isn't activated, the remaining hum could either be because of a harmonic of the 60hz hum, or that the hum you are hearing isn't mains (60hz) in nature.
The best way I find is to set a single filter to "notch", give it the widest possible width and then whilst playing the clip slide the frequency up and down. You'll hear the affect of the filter in real time, so you should be able to zero in on the offending frequency.
Once you've found it you can then narrow the notch to filter out the hum but leave other nearby frequencies (that might be part of say speech) less affected.
You may need to use another notch to catch a harmonic if one is present.
