[FFmpeg-user] audio noise filtering

[Ricardo Kleemann]

Hi,

I know almost nothing about audio filtering, and I wanted to better
understand more about it. I would like to filter out some low level
hum/noise from an mp4 file (h264/aac) and I understand there are different
types of filters, for example, a noise gate.

Can someone provide me with different configurations (command line syntax)
for noise filtering that I can experiment on the mp4 file and see the
results?

If it helps, the video is a recording from a church service (kind of like
an auditorium type location), and I was looking for ways to enhance the
audio.

Any help is appreciated

thanks
Ricardo
