The heartbeat loop was 100% generated in Audacity.

In order to do it, I generated a chirp (Sifflet in french) with a starting frequency of 100hz and and ending frequency of 1hz.
The amplitude was also reduced from 0.75 to 0. The duration of this chirp was set to 0.5 seconds.
To make the second part of the heartbeat, I generated another chirp, with a higher starting frequency, a lower amplitude at the start and a duration of 0.25 seconds.
I shifted the second chirp so that the two chirps simulated a full heart beat.
I then added some silence at the end of the cycle, and then I repeated the cycle 10 times.
I added some reverb and augmented the bass (as well as lowering the treble) to smooth the sound and make it sound like a deep heartbeat.

I recorded myself breathing, and I added this sound while making sure that 3 respiration cycles would perfectly align with 11 heartbeats, in order to make a perfect loop.

Typologie/morphologie de P. Schaeffer

Le battement de cœur est une impulsion variée (V'). Étant simplement répété et ne variant pas au fur et à mesure des répétitions, on ne peut pas selon moi qualifier cette boucle d'itération variée (V'')

Masse : Ce sample est composé de sons cannelés. En effet on entend la hauteur du son des battements de cœur, mais la respiration (son complexe) s'ajoute par dessus.

Grain : Le grain du son du battement de cœur est très lisse car purement sinusoïdale, cependant le souffle par dessus est lui rugueux.

Dynamique : Les battements de cœur ont une attaque assez abrupte suivie de deux pics et d'un relâchement immédiat. Le souffle quand à lui à une attaque assez douce, une longue phase de sustain et un relâchement lui aussi doux.

Profil mélodique : La transition entre les deux notes qui composent le battement de cœur est assez scalaire.

Profil de masse : Les battements de cœur ainsi que le souffle sont d'un niveau sonore similaire, cependant les battements de cœur sont bien plus graves.
