Hello! Been a while since last time I posted here.

In all my years of recording I have never bothered to learn what the specified frequency response (FR) of a microphone really means. I have always thought it means that the mic wont capture anything outside of the FR range, but is that really true?

A measurement of the frequency range that can be handled by a specific piece of electrical equipment or loudspeaker when referenced to amplitude. A graph of all the frequencies plotted versus level is the Frequency Response Curve of a particular piece of equipment.

Anyone have any frequency response curves of a Figure 8 mic? I believe that they should exhibit a 6 dB/octave slope, but I haven't seen any data.

So to me this has a somewhat obvious answer, but I've never actually heard it discussed so I'm not certain, and I'm not sure many people have thought about it too much.

I got a blue tube stereo tube preamp with the 12ax7 tube. As well as a apex 435 condenser mic. I want to know what frequencies these add or cut. (how they color the signal). Any idea where I can get this info?

Also is it possible to get the same info for these speakers? Altec Lansing ACS33?

Thanks

Is there software or something that I can use to see what the frequency response of my speakers are? Like say I do a full spectrum sweep, I want to know what frequencies are being boosted/cut by the speakers. Is there some way to do this?

I know an engineer who eq's his recording with peaks at the frequencies where the ear is the most sensitive. His goal was to make the sound "Louder" with out pushing compression and limiting hard. I had never seen this. His results were O.K. sounding.

i've seen some priced at 100 dollars each.
i've heard if you can make it sound good on crap then it can sound good on anything.
any suggestions on where to look first?

Is it possible that mic frequency response can vary with the temperature of the microphone? I recently used two Shure KSM-32 mics, that had been inadvertently stored at around 50 degrees F, to record a grand piano. These mics are generally pretty useful for the piano but the results in this case seemed better than usual.
