Si l'on «écoutait» […] un système stochastique, notre oreille pourrait distinguer éventuellement des notes de hauteur (de fréquence) bien définies, mais nous entendrions en outre un «bruit» un peu comparable à celui d'un torrent. Si l'on représente sur un graphe l'énergie de vibration en fonction de la fréquence, on obtient le spectre de Fourier […] 2, record 2, French, - spectre%20de%20Fourier

L'échantillonnage d'un son consiste à enregistrer sa valeur à intervalles réguliers sous forme numérique. La fréquence d'échantillonnage est le nombre d'échantillons prélevés par seconde. Plus cette fréquence est élevée, plus l'enregistrement est fidèle à l'original, et inversement. 3, record 3, French, - fr%C3%A9quence%20d%27%C3%A9chantillonnage
