Abstract
A method for reproducing an acoustic signal from a digital signal, the digital signal being formed of successive bit sequences each having bits representative of the amplitude of an acoustic signal at a time sample, the method including (i) providing a plurality of transducers configured to emit acoustic signals that are wave trains having each a duration lower or equal to the duration of one time sample and including at least one oscillation per time sample, and (ii) successively, for each bit sequence, having each bit associated to at least one of the transducers and independently govern, depending on its value, amplitudes of the acoustic signals emitted by its associated transducers.
