I've asked you before & you failed to produce any evidence of your claim about me - I'm asking again - care to point out an example to back up your assertion?

If you fail to do so I would ask you to desist from this.

Bill,
Interesting, but presumably unintended implications.

Are you so forgetful? Others aren't, I can't be bothered to go trawling back over stuff to provide you with evidence of what you and others already know, what's the point? Coming over all innocent doesn't cut it anymore. It doesn't matter....space will probably get a bee in his bonnet too, again he knows what I'm talking about.

Hang in there Markw4 and 99, but I just can't put the energy into attempting in proving the 'unprovable' i.e. whether I hear differences that I talk about, whether Jack Bybee knows what he is doing, etc. I am just going to keep going, and report in when something comes up that I feel might be shared with others.

This is the point, even if you "prove" it someone will "prove" that you haven't by undermining the test procedure by saying something like...oh...I don't know....it wasn't scientific enough for my liking.

And we haven't even begun to introduce the more recent work on placebo effect into the mix.

back to lurk

Of course not, only just IF you want the most accurate reproduction.
And those mics are almost never used in a recording studio. This is the gold standard in studios for almost 70 years. Freq response graph at bottom.

Most engineers will filter out anything not in the instruments range. Why keep noise below 100hz in a recording of a female vocal? And the best filters are microphones.

With the classic HF peak. A lot of microphones that recordists love have a "presence" peak. To be fair the crooner sound popular in the 40's was better served by ribbons.

Most microphones have other useful characteristics. For example, RIBBON microphones are very often used for human voice. Why? Other microphones are directional, or more convenient to operate than B&K omni mikes, but Crystal Clear did many, many recordings with B&K 1/2" mikes, as have several others.

Yeah, recording mikes are not the measuring mikes. Second, it is pretty difficult for frequencies >20kHz to find its path to the eardrum and make some stimulation there.
