I have noticed that many podcasts are plagued with a Buzz/Hum in their audio. I recently built a new computer and noticed that there was an awful buzz in all my recordings. I did some research and found a Buzz/ Hum eliminator.

Here is a link to the one that worked for me

Yes, the dreaded groundloop problem. Radioshack also sells something simular. You can also try HumX

The Radio Shack ground loop isolators (http://www.radioshack.com/product/index.jsp?productId=2062214#) are excellent, but they're $20 each. I buy suitable units on eBay for less than $5 each. If you need them in a hurry, Radio Shack is the way to go. Every store I've checked had them in stock.

I'm sure you could buy them cheaper online like anything else. But if you have a broadcast coming up and have to have them right away.

I bought this one from my local Best Buy. It's meant for a car, but it works just fine for an audio mixer. I used to have a terrible issue with hum and noise, and as soon as I slapped it on the main out, I immediately saw a difference.

Many Podcasters suffer from a ground loop problem. I hear it nearly every time we have a skype guest on

If you are pre-recording and using programs like Adobe or other audio work stations, you can also filter the ground loop out.

Although true, it's best if you can get it at the source before recording. Post production should always be used as a means of final tweaks to the audio. You should always try to record the cleanest sound possible up front. When removing noise and other tones from your audio you destroy a bit of the good portions as well which takes away from the final product.

Yes it is always better to fix the source. In my case the hum is introduced via the computer. Post Production on voice tracks is the only place I use it.
