Abstract	The BISOU (Balloon Interferometer for Spectral Observations of the primordial Universe) project studies the viability of a balloon borne spectrometer, pathfinder of a future space mission dedicated to the measurements of the CMB spectral distortions. Taking into account the specificities of balloon flights, a concept based on a Fourier Transform Spectrometer covering a spectral range from about 90 GHz to 2 THz is being studied and modelled. I will present the scientific goals, the instrument and payload concept together with the results of this CNES phase 0 study evaluating the sensitivity of this project to the CMB Compton y distortion and CIB measurements. leaflet
