A unified mathematical technique for analyzing a one-dimensional Doppler effects by a moving interface is presented. Exact and closed form expressions for stress waves are obtained. The solution for the stress has no restriction not only for the motion of the interface, but also for the wave nature, impulsive or time-harmonic. As an application example, the Doppler frequency shifts by the uniform and back and forth motions of the interface are discussed for the time-harmonic wave
