Title (EN) PROCESS FOR IDENTIFYING AUDIO CONTENT
(FR) PROCEDE D'IDENTIFICATION DE CONTENU AUDIO
Abstract: front page image
(EN)A fingerprint of an audio signal is generated based on the energy content in frequency subbands. Processing techniques assure a robust identification fingerprint that will be useful for signals altered subsequent to the generation of the fingerprint. The fingerprint is compared to a database to identify the audio signal.
(FR)Une empreinte d'un signal audio est produite sur la base du contenu énergétique de sous-bandes de fréquence. Des techniques de traitement permettent d'obtenir une empreinte d'identification robuste utile pour les signaux modifiés consécutivement à la production de l'empreinte. L'empreinte est comparée aux empreintes d'une base de données pour identifier le signal audio.
