Welcome to Sam Casas Sound Design & Mix


My mission is to help you bring your audio vision to life. I have over 20 years experience and a passion for staying up to date with the latest techniques and technology. I look forward to hearing from you!



My Story

A passion for detail

After graduating from UCSD’s Revelle College as a Music Technology Major in 1999, I moved to Los Angeles to pursue a career in Audio Post Production. I quickly found my niche working in commercials for huge brands such as Nike, Microsoft, Target, Starbucks and Old Spice to name a few. To date I estimate that I have mixed over 500 commercials.

In addition to commercials, I also have a strong passion for film and television. My desire is to bring feature quality cinematic sound to every project, big or small. In 2015 I joined the Union (M.P.E.G.), I am an associate member of the Cinema Audio Society (C.A.S.), and a member of the Motion Picture Sound Editors (M.P.S.E.)

Please check out some of my favorite Sound Design and Mix projects, and I hope to work with you soon!

Only the Best

Cutting edge tools and techniques

 At my private studio in the hills of Studio City, I edit and mix in Pro tools Ultimate, with hundreds of world class plugins. I always keep my studio up to date to ensure I have the best tools available to bring your story to life. I love staying active in the audio community, staying connected with colleagues and mentors who are also at the top of their game. I hope to never stop learning and would love to share my knowledge and experience with you.
