Abstract: A method for simultaneous playback of audio tracks from digital transceiver devices, which are adapted to define a communication network. The digital devices store audio tracks to be played. One of the digital devices is actuated as a Master device (M) and the remaining N digital devices as Slave devices. The master device generates a pilot signal by selecting a pilot audio track to be played from among stored audio tracks and by adding a synchronization frequency (fS) to the pilot audio track, having an assigned value that falls out of the sound wave frequency range. The Slave devices receive a pilot portion of the pilot signal and extract the synchronization frequency and the received part of the pilot audio track. The slave devices use the pilot to identify a stored track to be played using the synchronization frequency as a sampling frequency.
