Actually the most interesting subject in physicality of ear to me is not the cochlea damping but the fact that brain and ear are liquid decoupled and whatever brain hears is transmitted through a liquid pressure wave. Of course it is the case if a person is not a Bush-republican… BTW, is it possible to do liquid damping/decoupling with diaphragm in order to kill the “artefact of microphone diaphragm resonance, made worse by excessive proximity”?

I thought that eventually you would take my hint.... liquid damping in microphones is something I have given some thought to - especially given that air comes under 'fluid dynamics' - but I will get to my own solution shortly.....

Andy, let be a let bit more practical as it is what I uselessly try to do in audio. Would you comment on my feedback above about your recordings?

Also, all of your recording has very idiosyncratic, very shallow and very noisy midbass, there is no lower bass weight in any of the recordings (I was listening only classical recording - I do not care about others). I initially thought that “no bass” was the properly of the recording environment but then I decided that it is something in your recording chain – microphones, preamps, A/D or whatever. Can you comment on it? Your bass basically does not exist below I would say 45Hz and whatever is near 45Hz is very purely defined and very badly articulated. Andy, are you using ported monitor to conduct your listening experiments?

I did comment. I like mushrooms.

But seriously, there is not much to be gained by directly answering your comments about smoke or air or mushrooms. Sounds 'popping up like mushrooms' implies many things but you will have to be clear about your criticism in order to be answered with any value.

I will say that you could not (in your wildest dreams) imagine worse pre-amps, converters & cables which my poor microphones were connected to (Jim has some details).
Also, with these microphones (as I will elaborate upon later) there is the issue of 'callibration'. More later....

For now, my replies will be very slow over the next few days as I will be in Germany presenting my work and may not be able to reach a computer or have time to reply.

Also, if you are hosting a few of my files, you might also put one of the string quartet recordings there too - firstly, as this is the only recording which represents a 'wet' acoustic and secondly, as this is a very clear example of strings recorded without resonance on sustained notes (constant excitation resonance) - something no other microphone can do to this extent. More on this critical subject later too.

Best regards,

Andy
