Okay,
I downconvert it to 96 kHz on Cool Edit and listen to it, and it sounds like it say "Yao keep?"
I alsow downconvert it from 192 Khz to 48 Khz, and later from 192 Khz to 22 Khz.
From 22 kHz i adjust it to 44 Khz to makes it player twice as fast. As it playback twice as fast, it sounds like a cat streaking and screaming...
I would like to make a slight correction, the recording signal to noise ratio is about -45 dB, not -48 as i check it again. About half the dynamic and S/N of 16 bits limits of CD which is -96 dB max.
Then I open it on WaveLab Lite, and its play at 192,000 sampling. So, that means my soundcard can play up to 192,000 Hz per sec....amazing...
