Abstract
(EN)
The present invention relates to the field of audio signal processing. Disclosed is an audio signal processing method. The audio signal processing method comprises: obtaining an inputted audio signal (101); performing analysis to obtain an audio characteristic of the audio signal (102); determining a vibration characteristic corresponding to the audio characteristic (103); and generating a vibration signal corresponding to the audio signal according to the vibration characteristic (104). An inputted audio signal is automatically converted into a vibration signal according to a vibration characteristic corresponding to an audio characteristic of the inputted audio signal, so that errors caused by manual operations can be avoided and vibration signals may have higher universality.

La présente invention concerne le domaine du traitement des signaux audio. L'invention concerne un procédé de traitement de signal audio. Le procédé de traitement de signal audio comprend les étapes consistant à : obtenir un signal audio entré (101) ; effectuer une analyse pour obtenir une caractéristique audio du signal audio (102) ; déterminer une caractéristique de vibration correspondant à la caractéristique audio (103) ; et générer un signal de vibration correspondant au signal audio selon la caractéristique de vibration (104). Un signal audio entré est automatiquement converti en un signal de vibration selon une caractéristique de vibration correspondant à une caractéristique audio du signal audio entré, de telle sorte que des erreurs provoquées par des opérations manuelles peuvent être évitées et des signaux de vibration peuvent avoir une universalité plus élevée.
