Testimonials
What music creators are saying about Automix
"I have to say after nearly 40 years mixing, recording and playing professionally, I am very impressed with your product. Most engineers want to complicate a mix… when a clean simple mix with good levels and panning usually wins. My wife has heard every tune from hundreds of artists out of my studios, and says you do in minutes what I used to take days to do."
Steve Callahan, NC, USA
Retired studio engineer
"These AI mixing and mastering tools are perfect for us bedroom artists who know the basics, but don't have the time to dedicate to learning and purchasing thousands of pounds of equipment/software or hire out a £100 per song."
Amina Bhatt, Leicester, UK
Independent electronic producer
"I would like to give my thanks to you guys over at Mix Check Studio for helping me become a better producer! If it wasn't for you guys, I wouldn't have had any idea that most of my beats out of my collection need more work! I had no idea about a lot of issues you guys mentioned in your analytics. If it weren't for the very accurate and constructive critiques on my beats, I wouldn’t be where I am now! Learning more things with each new beat I make and upload for testing every time!"
Lucas Fernandes, São Paulo, Brazil
Hip-hop beatmaker
"I like the concept of having a pair of "external ears" judging my work, a pair of ears that are not human and not influenced by tastes, moods, or physical differences (different ears, hearing loss, etc..)."
Hiroko Watanabe, Sapporo, Japan
Composer and ambient sound artist
