Patent

CA 2318552

Audio recording occurs by input through a microphone (16) allowing storage thereof in memory (28). Control of the power supply (20) is affected with an on/off switch (22). The memory is addressable (30) to allow for playback through a typical loudspeaker (40). The audio data may be passed through a compressor (26) to reduce storage requirements. A decompressor (36) processes appropriate audio output to the loudspeaker (40) during replay.

L'enregistrement audio se fait par mise en mémoire (28) d'une entrée passant par un microphone (16). La commande de l'alimentation électrique (20) se fait avec un interrupteur marche/arrêt (22). La mémoire est adressable (30) de façon à permettre une lecture reproduite par un haut-parleur classique (40). On peut faire passer les données audio dans un compresseur (26) afin de réduire les besoins en espace de mise en mémoire. Un décompresseur (36) traite une sortie audio appropriée pour qu'elle puisse être utilisée par le haut-parleur (40) lors de la lecture.
