Podcaster’s problem: If you are recording in not 100% perfect environment you want to make sure that your voice stands out above anything else in the background. Compression can achieve just that.
Compression is a great thing when producing audio but can be overused when it comes to podcasting. You want to make sure your sound is natural and not like a CHR radio station. A little light compression will even the peaks and valleys in your audio to ensure a pleasant experience even within a listening environment with external noises.
1. Go to Effects > Amplitude And Compression > Dynamics Processing.
2. Start from a preset such as Boomy Kick.
3. Tweak the on screen graph until you have reduced the dynamic range of your audio while still keeping a natural sound.
