I produced this sound only with audacity, 100% synthesized.
To create this sound on Audacity, I first generated one chirp with a frequency of 95 (Hz) to 1 (Hz) and an amplitude of 0.65. Then I generated two other chirps, for each of them I changed the frequency and the amplitude. I increased the frequency of each and I lowered their amplitude. I precisely modified the disposition of the different sounds to create a quick heart beat. After the mix and render, I added an effect of fade in at the beginning of the sound. Then I added an effect of invert on the whole sound. I copied the sound several times to create a repetition of the heart beat. Then I put some silence and I modified the speed, the tempo and I used the reverb effect.
To make the sound more realistic I also modified the bass and treble. At the end I changed the tempo again to have a quick and deep heartbeat.
Typologie/Morphologie de P. Schaeffer
Descriptif :
Je pense qu'il s'agit d'une impulsion complexe(X') répétée ce qui pourrait éventuellement tendre vers une itération complexe (X'').
Masse: Il s'agit d'un son seul, qui est répété et travaillé en boucle ce qui lui confère un rythme plus prompt.
Grain :
ll s’agit d’un sinusoïde, le son du battement de coeur est donc lisse.
Dynamique :
Le début du son n’est pas violent mais plutôt profond, intense. Cela rappelle le bruit des basses. Le rythme est plutôt rapide, et le son comporte des pics de tension et des relâchements succincts.
Profil mélodique : Il s’agit d’une variation scalaire puisque les battements de coeur sont réguliers et rythmés.
