Wiltshire, UK (remote)
VP of Engineering and Audio Technology, 2020 to present
LifeScore is a small startup out of Abbey Road Studios applying AI technologies to create adaptive soundtrack music for videos, wellness, games, streaming, and embedded applications. And cars, with partnerships with Bentley Motors and Audi for the first automotive application composing music based on driving and road conditions.
Developed and implemented algorithms to analyze real-time CAN Bus telemetry data, to direct the structure of the composition, to create the composition on the fly, and to sequence and mix combinations of audio samples. Extended the concept to environment tracks with a set of algorithms to generate continuous environment sounds from a tiny set of samples.
Designed and implemented the in-house CAD System for building adaptive music. Composers can import and validate audio files, construct relationships between them, set parameters, perform simulations, analyze the results, and generate metadata for the compose engine. And built a high-performance compose engine.
