Intrinsic Audio Recognition and Fingerprinting

Client:Confidential technology programme· Engagement:OEM scientific and engineering development

Challenge

Recognise audio, events or sound objects through intrinsic structural characteristics rather than relying only on external metadata.

Why the problem is difficult

Robust recognition must survive noise and transformation and scale to large indexes.
