Audacity sound editor, audio editing, cleaning audio, denoising sound
Recently, we have been looked at the process of editing and cleaning sound. See the previous three postings: cleaning and editing(1) and editing(2). Then, we looked at a very popular Mac wave editor, Amadeus Pro. Most recently, we looked at basic sound editing in Amadeus.
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”.
The result is a chunk of audio that sounds very professional.
