The diversity of wave modes in the magnetic gas gives rise to a wide variety of nonlinear phenomenaassociated with these modes. We focus on the planar fast and slow magnetosound waves in the geometryof a flow where the wave vector forms an arbitrary angleθwith the equilibrium straight magnetic field.Nonlinear distortions of a modulated signal in the magnetic gas are considered and compared to thatin unmagnetised gas. The case of acoustical activity of a plasma is included into consideration. Theresonant three-wave non-collinear interactions are also discussed. The results depend on the degree ofnon-adiabaticity of a flow,θ, and plasma-β.
