Hi there.
I have an interview with a lot of AC hum. I'd like to remove as much
of the hum as possible. This is not for broadcasting. I just want to
be able to hear what the persons on the recording are saying.
I've looked at the sound in a frequency spectrum analyzer[1]. The hum
looks just as consistent as it sounds so I guess there must be a way
to filter it out. I just don't know which linux tool will do it for
me.
Very sharp notch filter?
