According to my pocket diary, there are a few
more: yocto, Yotta, zepto, Zetta, pico, Peta.
There is also deci (d) and deca (da).

Thanks to everyone who responded to the posts re file formats.
Does lossless A = lossless B (commutative property?) in ALL instances. Does
every lossless file type use all 16 bits (e.g.) for the net resolution, or are
one or two bits used in hand-shaking protocols to insure transfer accuracy
Sorry to get pedantic, but K is in common usage to mean 2^10 and there has
been lot of confusion about mega being 2^20 vs 10^6 for storage. (In fact,
I think someone sued Seagate or Western Digital over the discrepancy).
To fix this, IEC 60027-2 (2000) defines a set of prefixes and abbreviations

In summary, my reasons for not recommending MP3s is that they are already
“psychoacoustically tainted” and not the equivalent to actual stimuli
even if perceived by normal-hearing listeners as equivalent. Frequency
response isn’t the culprit. And with today’s technology, there’s

Eric B has already addressed this; lossless

Unlike kilohertz (kHz), the K is capitalized when
referencing kilobytes (KB) or kilobits (Kb).

For me the lowest acceptable bitrate for listening to music is 256kbps with
MP3s. I still prefer lossless over any MP3. It's not that I can spot or
describe any specific artifacts with 320kbps compression, but listening to
lossless audio just feels betters.

Hi Eric B.,
Thanks for your detailed and informative reply.
While drafting a recent Sursound post regarding KEMAR, I did a Google search to
make sure I was spelling Zwislocki correctly. One reference that appeared at
the top had something to do with inner ear simulation software--I need to go
