About

I'm Andrew Grathwohl, a software and systems engineer and technical researcher specializing in multimedia, digital signal processing, and content production. My work sits at the intersection of audio, technology, and creative expression.

After years in New York City's vibrant tech and media scene, I relocated to Nashville, Tennessee, where I now live and homestead with my wife and son. Together, we run the Bon Aqua Computer Club .

Digital Freedom Advocate

I'm a passionate advocate for digital freedom and technological autonomy. My commitment to free software, privacy, free speech, and right-to-repair isn't just philosophical—it's woven into everything I create.

Sonic Multiplicities

←→

For over 13 years, I've been pioneering the future of musical AI through my project Sonic Multiplicities . What began in 2010 as a radical musical philosophy has evolved into a trailblazing platform that continues to make groundbreaking innovations in real-time musical AI.

Sonic Multiplicities represents the most extreme effort ever made towards empowering the solo instrumentalist with software. The project constructs a unified, broadened musical consciousness by leveraging neural networks, digital signal processing, and free software principles.

My work with Sonic Multiplicities earned recognition from SEAMUS (Society for Electroacoustic Music in the United States), where I was honored for pushing the boundaries of what's possible in electroacoustic music. The project's innovations include:

• A real-time musical AI that can "talk back" to human performers
• The HyperMusic framework, a permissive and flexible approach to music distribution
• Novel fundamentals that emphasize the soloist's creative expression
• An AI free improvisation "friend" that responds with genuine musical understanding

What sets Sonic Multiplicities apart is its approach to AI as a collaborative partner rather than a replacement for human creativity. The system begins and ends with acoustic output from a human being, creating a feedback loop that enhances rather than diminishes the human element in digital music creation.

Audio Engineering & Mastering

As a mastering engineer under the moniker Sacred Data , I've worked with numerous artists across genres. One of my proudest achievements was mastering Photay's self-titled EP , a breakthrough electronic music release that received critical acclaim.

My approach to mastering combines technical precision with artistic sensitivity, ensuring each project maintains its creative vision while achieving professional sound quality.

Audible & Audiobook Production

During my tenure at Audible, I served as Director of ACX audio operations, scaling production from 200 to over 3,000 audiobooks monthly. My contributions to the field were recognized with an Audie Award for excellence in audiobook production.

I'm also the inventor behind Audible's voice search technology (US Patent #9412395), which revolutionized how listeners discover content.

As "Andrew the Audio Scientist" , I created educational content demystifying audio production techniques for creators and listeners alike.

Film & Television

My background spans beyond audio into film and television production, where I've applied my technical expertise to create immersive viewing experiences. This cross-disciplinary experience informs my approach to multimedia projects, ensuring technical excellence across visual and auditory elements.

From NYC to Nashville

My journey from the fast-paced tech scene of New York City to the creative community of Nashville represents my evolution as both a technologist and artist. In Tennessee, I've found the perfect balance between cutting-edge technology and a connection to the land through homesteading. This unique perspective influences my work, combining technical innovation with authentic creative expression.
