Here are the series of audio mastering software processors I've used on the over 30,000 songs I've mastered since 1999. In this video, I use mostly izotope ozone plugins because it's easier to explain using them. In real-life, I do mix in a few hardware pieces, and a waves plugin.
Don't spend 1-2 years (please never), 6 months, or even 6 weeks learning how to professionally master audio. Not to mention waste a ton of money too. Not when I can show you EVERYTHING you need to know in ONLY TWO HOURS with my Audio Mastering Secrets Video Series!
