About

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. I’ve edited 50+ podcast episodes, mastered audiobook productions, and created 400+ short-form videos—helping clients generate views from 5K to 290K and taking a faceless YouTube channel from zero to nearly 300 subscribers in just five months.

Lately, I’ve also been strengthening my workflow with AI assistance while keeping the content human and client-friendly. I build end-to-end AI-narrated video projects (scriptwriting, voice generation in English and Spanish, editing, and music synchronization) and use AI tools to produce faster without sacrificing quality. My goal is always the same: clean sound, strong pacing, and delivery-ready files for the platforms that matter.
