FIELD: information technology.
SUBSTANCE: method provides generation of a synchronisation signal (Si synch) from a synthetic audio file, initialisation involving recording parametres which include a list of preferred instruments in the portable communication device; generation, involving analysis of information read from synthetic audio file relating to each instrument for which a track may be extracted in the synthetic audio file, and deciding which extracted track is to be used for generating the synchronisation signal (Si synch) as a function of said parametres. Parametres include a predetermined frequency threshold, and reading and analysis apparatus can detect frequency of notes in the synthetic audio file for each extracted track.
EFFECT: more accurate synchronisation of a multimedia peripheral device.
