Sounds good to me and eases my crotch while stealthing.
As long as you dig it, that's what counts.
Whats truncating all about anyway?
First, check out
this Archive thread re AD/DA to understand bit-depth / word length / resolution (referenced as sampling precision in the link) and sampling rate (though you may already know about both, figured it couldn't hurt to include it).
Your Mic2496 is capturing the audio at 24-bit resolution and for the sake of argument, let's just say 44.1kHz sampling rate since it's compatible with DAT/JB3 (we could just as easily say 48kHz for the sampling rate). However, DAT/JB3 are capable of resolving only 16-bit resolution. So, that means the Mic2496 has 8 too many bits for the recording device. What to do with those 8 extra bits? There are two options: dither or truncate.
Check out this
Wikipedia blurb on dither and truncation. The key section is
Dither In Digital Audio.
