Abstract

Il est divulgué un procédé de classification du niveau de bruit d'un signal audio pour le test de la qualité de réception radio d'un système audio de véhicule automobile sous test. Le procédé comprend les étapes suivantes, réalisées par une unité de traitement: la réception d'un signal audio dit signal audio de test (207) ; la génération à partir du signal audio de test d'un vecteur de caractéristiques (208) ayant un nombre déterminé de composantes correspondant à des caractéristiques déterminées respectives du signal audio de test ; et, la détermination, sur la base des composantes du vecteur de caractéristiques du signal audio de test et sur la base en outre d'un modèle de prédiction (206) associant des composantes données de vecteurs de caractéristiques avec des étiquettes données caractérisant le niveau de bruit d'un signal audio correspondant, d'une étiquette (209) caractérisant le niveau de bruit du signal audio de test.There is disclosed a method of classifying the noise level of an audio signal for testing the quality of radio reception of a motor vehicle audio system under test. The method comprises the following steps, performed by a processing unit: receiving an audio signal called a test audio signal (207); generating from the test audio signal a feature vector (208) having a determined number of components corresponding to respective determined characteristics of the test audio signal; and, determining, based on the components of the characteristic vector of the test audio signal and further based on a prediction model (206) associating given components of characteristic vectors with given labels characterizing the level of noise of a corresponding audio signal, of a label (209) characterizing the noise level of the test audio signal.
