I don't know what that means.

Sorry... I must have been unclear.
Reading through the advertisements on microphone emulators, you might get the impression that they could turn your cheap microphone into the equivalent of a much more expensive microphone.
That's obviously not possible.
Specifically, if my cheap microphone can't capture any signal above 1200Hz (I said it was cheap!), if I record a piccolo concerto, I'll notice that my lots of notes are absent from my recording. Running that through a microphone emulator won't make that "missing" information appear, because it was never captured in the first place.
Did that make sense?
