Abstract: An application is to be synchronised with an audio content intended to be consumed by a consumer terminal. The content is provided in the form of a stream of audio data time-stamped according to a first time reference. The application is executed according to a second time reference. Synchronising the application with the audio content comprises steps of: obtaining (6.4) audio data of said time-stamped content, on the basis of the second time reference, in order to indicate respective instants at which said audio data is consumed by said consumer terminal; determining (6.6) information on the correlation between the audio data; determining (6.7) information on the time offset between the first and second time references on the basis of the determined correlation information and of data time-stamping information; and synchronising the application with said content on the basis of this time-offset information.
