Title: Weird hum in a SBD source how to fix?
Post by: AdamHuston on July 13, 2014, 08:56:19 PM

Have a SBD source that I'm wanting to matrix with my AUD recording.  It has an odd hum in it.  FOH gave me a mono feed, so far I've converted it to stereo but cannot figure out how to get this hum out of it or at least lower it so it's less noticeable.  I have Soundforge Pro 11 or Adobe Audition 3.0 to use.  If someone could walk me through this I would be grateful!  I will upload a sample tomorrow so that you can hear what I'm talking about

hum, often electrical ground issues.
in the US 60 hz and it's fundamentals can be notched with an EQ.

FOH gave me a mono feed

1) Since its mono just copy the good channel over the bad channel. (if left channel has hum, just copy right channel to left)
2) Wave Z-noise can take out a frequency if you have that plugin.
