Here are 2 very different versions of the same harp recording made in a huge cathedral with a 7 second reverberation time!
The first version, (though very grand), is considerably blurred by out of phase reflected sound arriving at the microphones. The mics used in version 1 are an M-S pair of AKG C414BTLs mounted on a stand 2-3m in front of the performer. On the floor at the base of the mic stand I also placed a pair of Shure MX393C boundary mics set at 90 degrees. Playing back this 2nd version of the same performance, recorded on the MX393s, it is hard to believe that this is the same concert! The reverberation of this enormous echoing space has all but vanished and the resulting recording is clean and sharp, and gives the impression of being much closer to the performer. No EQ or processing has been used. For further information visit:- https://martinmitchellsmicrophones.wordpress.com/2014/09/26/what-is-the-use-of-boundarypzm-microphones/
