Adalberto G.

Audio Engineer, Voice Actor, AI Data Specialist, and Musician

Top-performing Audio Engineer, Voice Actor, AI Data Specialist, and Professional Guitarist with 15+ years of experience across vocal performance, studio post-production, live entertainment, and AI audio evaluation. As an accomplished Lead Guitarist, I have performed in high-end corporate productions, luxury resort shows, and major national venues alongside renowned artists, bringing high-stage energy, sequence programming, and live FOH sound mixing expertise. As a Voice Talent, I specialize in character performance, dialogue dubbing, and conversational AI voice agents, delivering high vocal versatility, precise prosodic control, and regional accent adaptability across thousands of recorded utterances. As a Certified Pro-Tools Engineer, I manage complex multitrack audio pipelines—from building structured session architectures with marker alignment and JSON metadata synchronization to ensuring strict LUFS/dBFS loudness and true-peak mix compliance. Complementing my performance and engineering skills, I bring a solid background in phonetics, acoustic analysis, and AI data processing. I specialize in auditing voice models, annotating complex audio events, and evaluating speech synthesis to fine-tune generative AI models for natural, human-like delivery.
