Is my LT44 transformer suitable for audio (de)coupling?

Audio band white noise is totally dominated by high frequency noise !!
White noise has equal amounts of all frequencies.
** Wrong.
It has equal amounts of noise energy in equal amounts of bandwidth.
So, 50% of the noise energy is in the band from 10 kHz to 20 kHz.
90 % is in the band from 2kHz to 20 kHz.
95 % is in the band from 1 kHz to 20 kHz.
99% is in the band from 200Hz to 20 kHz.
Get it ?
We hear the HF dominate
because higher frequencies have more energy.
** No - because it does utterly dominates the energy spectrum.
