Today, we look at a free audio editor, Audacity.  In particular, it has a great noise removal effect.

Cleaning sound in Audacity – a voice track.

First, we create a track and use the red button to record a few seconds of silence, and then a voice.

The denoise effect in Audible.

Now, we swipe the “silence” part of the track, which is really a bunch of background and mic noise.  Then, we select the noise removal effect.

Then we tell the effect plugin to “Get Noise Profile”.

Then, we go back to the track and swipe all of it.  Then, pull down the effect again and choose “OK”.

Now, look at how the effect has removed the noise from the entire track, including the part with the voice recording on it.

The result is a chunk of audio that sounds very professional.

More soon.
