I’m Samuel Diaz, an audio engineer and video editor based in Buenos Aires with 10+ years of experience turning raw recordings into polished podcasts, ACX-ready audiobooks, and social media videos designed to keep people watching.

My goal is always the same: clean sound, strong pacing, and delivery-ready files for the platforms that matter.…
