Hello, Goran,

I think I prefer the freedom to use 24 bits for live recording as I 
don't feel as compelled to risk clipping in order to optimize level 
settings. Other than that, I look at higher bit rates (88.2 and 
above) as "just in case someone with better hearing) can hear 
something I cannot -- and my hearing isn't bad -- in fact quite good 
for my mid-50s.

I hope that these tests bring about a comfort level in the archival 
world with digitization at less than 96/24 and hopefully we don't see 
specifications for digitizing oral history cassettes at 96/24. While 
bits are cheap for storage, they aren't free. I know IASA says 48/24 
for everything with 96/24 preferred.

Cheers,

Richard
