A procedure for the emission of aromas/scents consists of playing, in a software, an audiovisual production with at least one encoded scent emission scene, wherein the software, for each encoded scent emission scene identified and decoded in the audiovisual production, sends a scent release signal through a wireless communication adapter (transmitter), which signal is received by a scent emission device through another wireless communication adapter (receiver). The scent emission device comprises a PCB which controls synchronized operation of a plurality of electrovalves coupled to a plurality of aerosols, for aroma/scent release, and a plurality of fan(s), to promote the a fast spread of aromas/scents, according to the encoded scent release signal received.
