In this paper we describe an innovative synchronization technique based on audio fingerprinting to help create a time base common to source content and receivers.We also introduce, as a relevant use case, the concept of hybrid content radio, a new radio service allowing the enrichment of broadcast radio with personalized audio content.Hybrid content radio is a novel radio service relying on audio replacement, and needing a precise synchronization between the main audio content and the enriching audio.We then discuss a variation of an existing audio fingerprinting algorithm, used to assess the proposed technique using real audio content.
