Phase shift in a two channel recording is generally inaudable if the phase shift is the same for each channel. If channel 1 exhibits a change in phase different from that of channel 2 at a given frequency the stereo image will tend to shift toward the channel having the leading phase. This phenomon raises much difficulity in producing good recordings. Proper microphone placement tends to have greatest influence phase of a recorded signal. Many recording engineers tend to frown on multi-mic recording, often using only two cardoid mics placed in closed proximity (~10-15cm apart) with axis of 90-120 degrees. To be honest, most recordings are suffer in this regard. Consider giving some good classical or jazz recordings by Telarc a listen. These guys know how to do it proper.
