I'm trying to wrap my head around this:

So to answer the question-- yes, the mic has to respond.  So if the worry is cellphone microphones, I simply don't see how the mic could deliver any

useful data whatsoever to the analysis software.

Will your mic respond? Or are the physics immaterial?

Hi list,

Suppose a bird sings a song in a frequency range around 1gHz. (Yes, "g"Hz)

The song the bird sings is always exactly the same.

The bird repeats its song several million times over the course

of an hour.

If I record at a sampling rate of 44.1kHz below the tree in which the bird is perched,

for a duration of one hour, would I be able to recreate the bird's song?
