Abstract
Various embodiments enable audio data, such as music data, to be captured, by a device, from a background environment and processed to formulate a query that can then be transmitted to a content recognition service. In one or more embodiments, multiple queries are transmitted to the content recognition service. In at least some embodiments, subsequent queries can progressively incorporate previous queries plus additional data that is captured. In one or more embodiments, responsive to receiving the query, the content recognition service can employ a multi-stage matching technique to identify content items responding to the query. This matching technique can be employed as queries are progressively received.
