It's an all synthetized sound, created on audacity. I wanted to recreat a basic emergency alarm, which can be use for cops, firemen or ambulance. I started by creat a track, then i add chirps. After, i duplicated the track and make a stereo of both. After, i copy and stick multiples times my sound. After, i chossed to raise the speed of the track, twice. I also modified a little bit the height. Then, i normalized the track. _______________________________________________________________________________je pense que c'est un son répété formant un groupe tonique, au timbre harmonique éclatant voir acide, dynamique et au grain lisse.
