The really interesting value is the noise density
shown in the upper
left corner (for the marker at 1100 Hz): noise density is -137.9 dB/Hz
Add 43 dBHz (for 20 kHz), and the resulting S/N ratio is -94.9 dB.
Which is 16-bit performance, even if the card is 24-bit.
Not quite. With a 16 bit card you wouldn't be able to pick up anything
at all @ -96 dB ... zilch!
Assuming this card otherwise works as promised (?), you will still be
able to pick up a conversation drenched in 24 dB of noise @ -120 dB.
So 20 "useful" bits - approx.
