We discuss results and limitations of a new model for the components of the solar intensity (I) an d velocity (V ) photospheric fluctuations. The model is able to take into account the complex behavior of a low-frequency p-mode, as observed inall the four I and V spectra. We also demonstrate that the solar I-V cross-spectrum provides a sensitive diagnostic for the interaction between the oscillatory and non-oscillatory components of the solar velocity and intensity signals.
