I’m Mario Crespo, an audio engineer and computer scientist specialized in technical sound design, audio programming, and audio AI.
With over 10 years of professional experience, I’ve worked across AAA games, media production, audio software, and AI-driven products. My background combines hands-on engineering with leadership and product ownership, allowing me to operate comfortably between creative teams, R&D, and business stakeholders.
I’ve served as CPO and co-founder of WitSound Technologies, where I led the creation of Audio AI products for the voice-over industry, including automated QC systems and end-to-end audio pipelines covering DSP, data augmentation, machine learning, and deployment.
Alongside product leadership, I’ve worked as a Lead and Senior Technical Sound Designer on multiple shipped titles, collaborating with composers, VO studios, and development teams to build robust, scalable audio systems using Wwise, Unreal Engine, C++, and Python.
I’m currently working as a Senior Technical Sound Designer at Rebel Wolves, while also consulting on Audio AI technologies and developing advanced audio tools and plugins.
