Veteran content ID that fingerprints AI songs at the moment they're made.
Audible Magic is a California content-recognition company with more than 25 years in the business and Emmy-winning technology, used by platforms, labels, publishers and studios to identify and manage rights. In April 2025 it partnered with Udio to fingerprint every track at the point of generation and register it with its ID system, so distributors and streaming services can recognize AI-generated tracks downstream and apply licensing rules. Its content ID is also available through partners like Music.ai.
