In this talk I will demonstrate a method dubbed active sound spectroscopy which makes it possible to fully characterize the hydrodynamics of spontaneously flowing liquids. To do so I will first experimenatlly evidence the free propagation of two sound modes in polar active liquids assembled from colloidal rollers. I will then show how to infer the material constants of this active material from the dispersion relation and the spectral width of these active sound modes.
