Yes, on a DAW, 1% linear scale and -38 to -40dBFS. The Triplett sound
meter I can borrow doesn't give me very reliable readings below 35dB
but I'm guessing the background sound levels involved were 20-25dB (A
weighted).  Now that I've have a recorder that records at both 16 and
24, I really should make an A/B comparison test using levels of this
scale.  Rob D.
