  • Stereo in sight and sound
    (These minor fluctuations were prob- ably caused by the difference in the angle that the sound made with the diaphragms of the cardioid microphones used, since these had then replaced ribbon microphones due to their better uniformity of response with frequency and … Very modern recordings are made using ribbon cardioids, which may well produce even better phase coherence .) .

  • Handbook of Signal Processing in Acoustics
    In near coincindent microphone techniques, the distance between microphones is selected in a way that the microphone signals are effectively in same phase at low frequencies, and in different phase at high frequencies. … the most used near coincident technique is the ORTF technique, in which two cardioid microphones are spaced … The too high coherence produced by first- order directional patterns can be enhanced using information of directional …
