Wicked Game (cover) - London Grammar Using Shure SM7 Moving Coil Inside Magnetic Field Microphone

 


Notes originally written to my friend Markos:

When we talk about dynamic microphones we really mean a moving coil inside a magnetic field microphone. 

A similar mic to the SM57 (God Only Knows - Brian Wilson vocal, possibly uses the Shure Unidyne III which is really the same to SM57) is the SM7. SM stands for Studio Microphone.

Here is London Grammar on a cover using the SM7. Listen for what we were discussing on how humans sing the first few milliseconds of the note flat, and then good singers immediately raise pitch so that it sounds correct to listener's brain.

The singer is very close so the mic will receive spherical waves instead of plane wave fronts so there will be proximity effect, boost of bass and mid. They probably correct bass using a external electrical filter or they might use the filter inside the mic activated by a switch on the side.
