The paper is concerned with the approach developed within the ANR Project StaRAC, and it gives an overview of its main results. The objective was to reconsider the concept of stationarity so as to make it operational, allowing for both an interpretation relatively to an observation scale and the possibility of its testing thanks to the use of time-frequency surrogates, as well as to offer various extensions, especially beyond shift invariance. MOTS-CLES : stationnarite, test, temps-frequence, distances spectrales, apprentissage, autosimilarite
