Please Help.


I recently conducted a telephone interview for an enterainment/community website, but on the recording, I cannot hear the other side of the conversation over a persistent buzzing. So I'm trying to either reduce the buzz or enhance the voice, because little of it is audible in its present condition.

I used a standard Radio Shack Telephone-> Line In adapter, and the line in function of an Iriver 120 audio device. The call was transatlantic, conferenced through New York. When I put the resultant mp3 on my hard drive, the whole thing shows up with almost no peaks or valleys.

What can I do to hear the voice better? What software can I use (if any), where can I get it, and what do I have to do with it?

Please Help.

Welcome to HRC.

I have restored hours and hours of old-time radio tapes that had similar issue. First, using an EQ, find the basic frequency range of the voice and the buzz, hopefully they are much different, you can then raise and lower the approriate EQ ranges...also, good restoration plugins (I use Sonic Foundries old ones) have options to "learn" noise, get it's patterns and remove it, but be warned, they can be destructive if overused.

You might want to try boosting 1-4kHz. if theres not to much noise there. These are the frequencies that the ear is most sensitive at, and also, where the intelligibility of speech lies.
