I wanted to recreate an emergency alarm sound on Audacity. So, i have generated a noise (base on A : 440hz) with a sawtooth shape and Linear interpolation. Then, i added some effects, reverberation (by slightly decreasing the basic parameters, to avoid that the effect is too loud), but also by amplifying the bass and treble. After, I had to remove the saturation (-5 db) and copy the sound in a loop to reproduce the sound of an emergency alarm.
