Thanks for the answer. However I don't see why the amplitude is not affected in the case when the source moves slower than sound speed?

Does the amplitude of a wave changes when the source is moving? I am mainly interested in waves in a medium (e.g. sound, water...) No text about Doppler effect I have found mentions anything about the amplitude so I guess it does not change. However in the case if the speed of the source...
