The BBC have always had great faith on ribbon and moving coil presure microphones

After more than 70 years...

Attention before dismissing a microphone part 2

It seems singing needs less bandwidth than speech. When we sing more bass and treble frequencies are produced. And contrary to intuition the high male notes may have may have more  chest low content.


And a microphone that does not sound too good on speech for exactly the reason it may be perfect for singing.


For example:


Are you Lonesome Tonight - Elvis Presley


It may be safe to assume that no EQ change was done between the speech and singing part, see reference.


And of course a mic for singing should be tested by singing, not speaking, common sense.

A great book on microphones by the BBC

BBC engineering training manual, Microphones.


It explains so much. For example it is a joy to read what mass control. resistance control, stiffness control on microphone membranes mean, and what happens on each type of microphones.
