Robust Real-Time Identification of PCM Audio Sources

We propose a framework for matching a single PCM audio stream against multiple candidate audio streams. This framework allows for a real-time identification of a single audio stream w.r.t. the candidate streams. The identification is robust to signal delays of up to several seconds as well as to signal distortions due to lossy coding, a noisy environment, or analog transmission. An area of application is the query-by-mobile-phone scenario where a user transmits an audio stream recorded from the radio using his mobile phone as a recording device. The transmitted audio stream may then be identified using the proposed framework by real-time matching of the audio stream to all possible radio programmes.
