reducing background noise from mono recording

I’m on a Macbook Pro using OS 10.8.5 and Audacity 2.0.5 via .dmg installer.
I have a mono voice recording that was created using the Rev recording app on my iPhone 4s.
I’m a complete newbie regarding the ins and outs of audio recording/editing.
My recording was made with a radio on and the radio was closer to the iPhone than the people who were speaking.
What editing tool(s) are available (if any) that will enable me to maximize the voices in the background and minimize the music in the foreground, and how do I go about setting the variables in any specific tool(s) recommended. THANKS!

You should consider what you would do if you have no show. There are no tools I know of to rescue this performance.

Number Four:

The Four Horsemen of Audio Recording (reliable, time-tested ways to kill your show)
– 1. Echoes and room reverberation (Don’t record the show in your mum’s kitchen.)
– 2. Overload and Clipping (Sound that’s recorded too loud is permanently trashed.)
– 3. Compression Damage (Never do production in MP3.)
– 4. Background Sound (Don’t leave the TV on in the next room.)

Yes, I know how to best record audio when advance planning is possible. I simply had no choice or options in this case. It was a spur-of-the-moment recording of a spontaneous event. Thanks anyway.

We can only go with what you tell us. Now you’re a more experienced recordist.


Big picture — I’m assuming that there are some basic EQ, compression, filtering (etc) options that will help enhance the background voices and/or suppress the foreground music. That’s what I’d like some advice on. I’ve looked and some of the many “effect” options and have noticed that most require knowledge of frequency, amplitude, etc. in order to make adjustments that will affect the resulting audio in different ways. Those are the things I could us some help with to making “blind” adjustments. Thanks.

As Koz said, there are no tools that can rescue this recording. The frequencies of the music/voices on the radio are the same as the live voices. You are, in effect, asking how to separate the cream from the coffee.

There are brute force tools that can split very quiet sounds from very loud ones assuming the loud ones are your show. If the loud ones are the interference then that’s the end. Even if you go that route and the voices is dominant, you don’t walk away with a theatrical performance. You get a stuttery, odd-sounding, pumping voice.

If there was no other way to capture the voice, then I would have tried it that way, too.

This question might also be a violation of a forum policy of no involvement with law enforcement or the legal profession.
