Feel the sound

What started with original music and post-production for documentaries and commercial work gradually grew into a dedicated sound studio. In 2025, Symmetry Sound became its own entity, founded by Gerardo Martínez and Alejandro Durán.

Today, we work across original music, sound design, foley, recording, mixing and mastering for film, advertising and other creative projects.

Music is equally at the heart of Symmetry Sound. We develop and license original music, create our own musical projects, and work with artists to help them find and shape their sound.
