How well dose flac encode 3hz to 30khz sounds?

Light travels faster then sound, which is why some people appear bright, until
you hear them speak

Perfectly.  FLAC is lossless.

You must first record the 30 kHz sounds, i.e. digitize the sound by  
converting analog to digital, meaning that you must use a sample rate  
above 60 kHz.  Preferably you would use a rate much higher than 60  
kHz, such as 96 kHz, so that the frequencies near 30 kHz are not  
attenuated by the conversion process.

Once you have a recording of 30 kHz sounds, FLAC will encode those  
sounds perfectly, into a file that is smaller than the original.   
There is no frequency dependence in the format whatsoever, because  
the original file is preserved exactly.
