I looked at the video only for a few minutes... I think there is a fundamental flaw here (perhaps later on it takes those things into account, but I comment on the part I saw). The source the guy uses is a coaxial speaker and the microphone used in very close proximity. As such, all the music information comes only on axis and also, all the microphones are compared in the region of the maximum proximity effect buildup, so the low end is wrong.


Indeed, in this situation the main difference between the microphones will be frequency response of mid to the top end response. However, in the real life situation the 'microphone tone' rather comes from off axis response and (especially) from phase response integrity, which can be all over the place for a conventional cardioid microphone. In this case that 'on axis frequency response' becomes almost useless. This is one of the reasons one should always take the published frequency response charts with a (large) grain of salt and always audition a microphone in a real situation with complex sound sources...


Best, M
