audio hum
i don’t know if ppro 1.5 is equipped to deal with my problem, but let me be
brief yet give as much information as possible.
the mic was sitting on a table top podium that had a speaker on the front
side. the speaker gestured and hit the mic. the person sitting next to him
reached over to readjust the mic resulting in a slight feedback that develop-
ed into a hum that is loud enough to be annoying. i think the base of the mic
stand was touching the rim of the podium and picked up the vibration of the
speaker.
i have tried everything in audio effects from top to bottom, and nothing affects the hum. is this anything that anyone has dealt with successfully
within the abilities of ppro 1.5? it may require another piece of equipment,
but i sure hope not!
thanks for any suggestions i can get.

It always nice when budget permits having an audio guy on shoots to nip this. Hindsight 20/20. Audition may be able to help though. You can go into Spectral analysis, and generally find the exact ofending band of frequencies that are the culprits. Im no expert here, but have seen it used very effectively. You can cut out the offending audio using this spectral view, and copy/paste adjacent views in place of. It works much better than the noise reduction presets, but is much more time intensive to use especially if a long chunk of audio needs treatment. Hopefully someone who does this frequently can help you here. (maybe even post a tutorial on this subject.)

You could try using the EQ filter.
Go into the lower frequency ranges and use the sliders to remove the hum. I’ve done this on a couple of occassions and as long as the voice is not in the same range you should remove it effectively.

Hi JBM5707,
You can try and fix this problem in ppro, using the NOTCH effect (in audio filters).
You can use it on the bad audio track, then play around with the frequency cut to find the problem freq.
for example if you knew it was hum because of power-line problems. then just get rid of the 60HZ freq.Good luck,
Peace,

You can try to remove bad hum by reducing the EQ filter’s output gain under individual parameters. It’s a nice quick fix.
