My name is Juan Sierra and I'm a recording and Mixing engineer from Bogotá, Colombia. Sometime ago a friend of mine defined me as the right combination between Kant an Werther; a combination of rationality and passion. Im an Audio Engineer with a BA in Music and Audio Engineer. Which assures a precise and emotional job approach

Mainly, I do mixing engineer for musical projects. My work is substantially artistic so I like to take my time with a client to discuss the sound and vibe he/she is expecting for his/her art to get from me and my job. However, my work is also quite rational and precise as I plan and take care of every detail inside a mix to make it as good as I can.

Although I'm open to work on almost any genre, I feel more comfortable on Rock, Pop, Jazz and Latin. And depending on the project's needs I'll work on a digital based system or with a 48 ch Analog Mixing Board as the core of the system.

Besides that I also do Music Recording, Sound Design and remixing Engineer for audiovisual material ranging between commercial videos and advertising to full length movies.

Terms of Service

I usually like to state terms of service on a project basis; I don't usually ask for a decent quality recording in order to accept a mix and usually charge extra revisions after 3rd revision.
