Title
(EN) PROCESSING METHOD FOR SOUND EFFECT OF RECORDING AND MOBILE TERMINAL
(FR) PROCÉDÉ DE TRAITEMENT D’EFFET SONORE D’ENREGISTREMENT ET TERMINAL MOBILE
Abstract
(EN)
A processing method for sound effect of recording and a mobile terminal are disclosed in embodiments of the present disclosure. The method includes recording N audio signals generated from N sound sources, N being an integer greater than or equal to 2; obtaining location relationships of the N sound sources, determining a scene where the N sound sources are located in, and determining a reverberation algorithm according to the location relationships of the N sound sources and the scene where the N sound sources are located in; and performing a sound effect processing for the N audio signals according to the reverberation algorithm to obtain a reverbed sound effect.
(FR)
Des modes de réalisation de la présente invention concernent un procédé de traitement d’effet sonore d’enregistrement et un terminal mobile. Le procédé comprend : l’enregistrement de N signaux audio générés à partir de N sources sonores, N étant un nombre entier égal ou supérieur à 2 ; l’obtention de relations d’emplacement des N sources sonores, la détermination d’une scène où les N sources sonores sont situées, et la détermination d’un algorithme de réverbération selon les relations d’emplacement des N sources sonores et la scène où les N sources sonores sont situées ; et la réalisation d’un traitement d’effet sonore pour les N signaux audio selon l’algorithme de réverbération pour obtenir un effet sonore de réverbération.
