Title (EN) SOUND EFFECT SIMULATION METHOD, APPARATUS AND SYSTEM
(FR) PROCÉDÉ, APPAREIL ET SYSTÈME DE SIMULATION D'EFFET SONORE
(ZH) 音效模拟方法和装置及系统
Abstract: front page image
(EN)A sound effect simulation method, apparatus and system, for simulating the sound effect of a phonograph. The method comprises: performing band-pass filtering processing on an input sound signal by using a band-pass filter, so as to get an intermediate signal (110); and multiplying an envelope signal with the intermediate signal, so as to generate an output signal (120).
(FR)L'invention concerne un procédé, un appareil et un système de simulation d'effet sonore pour simuler l'effet sonore d'un phonographe. Le procédé consiste : à réaliser un traitement de filtrage passe-bande sur un signal sonore d'entrée en utilisant un filtre passe-bande, de façon à obtenir un signal intermédiaire (110) ; et à multiplier un signal d'enveloppe avec le signal intermédiaire, de façon à générer un signal de sortie (120).
(ZH)一种音效模拟方法和装置及系统,以便用于模拟留声机的音效。所述方法包括:利用带通滤波器对输入的声音信号进行带通滤波处理,得到中间信号(110);将包络信号与所述中间信号相乘,生成输出信号(120)。
