A mobile telephone has a receiver, a transmitter, a microprocessor and an associated memory. The memory includes a first-in-first-out (FIFO) queue and a static buffer. An audio signal carried by the mobile telephone is digitized and provided to the microprocessor. The resulting digital signal is continuously written to the FIFO queue. In response to a first command from the mobile telephone user, the microprocessor causes the contents of the FIFO queue to be transferred to the static buffer. Upon a second command from the user, the contents of the buffer are converted to an analog signal and played back over the mobile telephone's speaker.
Téléphone mobile doté d'un récepteur, d'un émetteur, d'un microprocesseur et d'une mémoire associée. La mémoire comporte une liste directe et une mémoire tampon statique. Un signal audio acheminé par le téléphone mobile est numérisé puis amené au microprocesseur. Le signal numérique résultant est enregistré en continu dans la liste directe. En réponse à une première commande provenant de l'utilisateur du téléphone mobile, le microprocesseur provoque le transfert du contenu de la liste directe vers la mémoire tampon statique. Après une seconde commande de l'utilisateur, le contenu de la mémoire tampon est converti en signal analogique et reproduit dans le haut-parleur du téléphone mobile.
