Abstract

In this work, a survey about how the audio codification formats affect in song recognition using fingerprinting systems will be developed. Initially, the robustness of each audio codec will be evaluated using different type of degradations. In order to do that, a synthetic environment is built, raising an own fingerprint system built from excerpts of 10,000 musical pieces and testing it against intentionally degradated queues. Among the used degradations, dynamic range compression, noise, pitch shifting or time stretiching can be found . Finally, after analysing each codec performance, a real case is developed using TV and radio channels content in order to compare results.
