Juan Sierra


I am a professional musician with an emphasis in Audio Engineering and a masters in Music, Science and Technology from the Center for Computer Research in Music and Acoustics (CCRMA) at Stanford, known for my strong knowledge in production, music recording and mixing. Often this knowledge is supported by deep understanding of physics and mathematics which have helped me develop great projects in acoustics, digital signal processing and software development.This is the basis, not only of my decisions, but of a precise and meticulous workflow without ever leaving emotivity and art behind.
