An addendum to see if anyone is awake. Or muddy the waters...

Using just the same original 48k file from Lang, and respectively the 
same Peak 4.03 and Soundhack 0.892 as I used before, and a yet to be 
revealed *Magic*Incantation*, here's some new 44k converted files from 
those programs:

Peak:
m("44khz_peak_rev.aif","//madranis.home.mindspring.com/insect");">http:
Soundhack:
m("44khz_shak_rev.aif","//madranis.home.mindspring.com/insect");">http:

How do you like those compared to Spark, Audition, the original, the 
previous versions from the same programs etc.?

Anyone other than Lang want to take a stab at the *Magic*Incantation*? I 
already told Lang. I think it reveals the source of the problem.

And here I thought you wanted to know the brand of the convertor chip!

Hi-MD at highest quality will still be only 44.1KHz/16 bit PCM. I would
love to see a device made that uses its "data space" as a simple storage
area for recordings at other resolutions, but I kind of doubt it'll every
appear.

>From what Walt has said, the ATRAC spec for *ATRAC compressed* recordings
actually has a wider effective range, which I believe he has said is akin
to 24 bit depth.

Whether or not that effective depth is actually audible if you use 44/20
or 44/24 bit digital transport of the files recorded, I don't know. I
should give it a try though, my Sony JB920 has a setting for "output bit
depth"  which I always assumed was simply to allow it to match up with
other fixed-word-length devices...

 best,
