dxRevive

This plugin is absolute must-have for every podcast creator. No matter if you record in a proffesional studio or you use a cheap smartphone, DxRevive helps not only to solve issues such as pops, noises and all that stuff, but it also enhances your voice sound greatly. It does miracles even with such low quality materials like recordings of phone conversations. If you ever used Adobe's Podcast Enhancer, DxRevive does the same job - but much, MUCH better, and it gives you much more control over the quality of the output.
