Abstract:
(EN) Disclosed are an audio device and a sound source correction method, the audio device comprising: a sound source storage unit for storing a sound source file; a digital/analog converting unit for converting, into a first analog audio signal, first digital audio data inputted from the sound source storage unit; an output unit for outputting the first analog audio signal; a microphone unit for sensing a sound source; an analog/digital converting unit for converting, into second digital audio data, a second analog audio signal sensed by the microphone unit; and a sound source correction unit for analyzing the difference between digital audio data of the sound source file and the second digital audio data, and correcting digital audio data inputted to the digital/analog converting unit by using the analyzed difference such that the second digital audio data approaches the digital audio data of the sound source file.
(FR) L'invention concerne un dispositif audio et un procédé de correction de source sonore, le dispositif audio comprenant : une unité de stockage de source sonore pour stocker un fichier source sonore ; une unité de conversion numérique/analogique pour convertir, en un premier signal audio analogique, des premières données audio numériques entrées à partir de l'unité de stockage de source sonore ; une unité de sortie pour fournir en sortie le premier signal audio analogique ; une unité microphone pour détecter une source sonore ; une unité de conversion analogique/numérique pour convertir, en secondes données audio numériques, un second signal audio analogique détecté par l'unité microphone ; et une unité de correction de source sonore pour analyser la différence entre des données audio numériques du fichier source sonore et les secondes données audio numériques, et corriger des données audio numériques entrées dans l'unité de conversion numérique/analogique à l'aide de la différence analysée de telle sorte que les secondes données audio numériques approchent les données audio numériques du fichier source sonore.
