Lossless

brother raffells, your definition of "lossless" is, i should say ... unique

i will not argue over this, but lets just say for great many people lossless is lossless whether its 32bit 192khz or 8bit 8khz

admittedly i am new to the forum so perhaps you folks developed your own language here ... i can respect that, but it would sadden me
 
lossless, or lossy refers to the ability of the compression/decompression to rebuild an exact replica of the data after passing through the compression process.
It has nothing to do with the sampling rate to generate the original digital data stream.
Meridian invented their lossless packing (MLP) which is a digital compression system that is capable or rebuilding the data stream, but it only achieves around 50% compression at best.
 
on a different tack and almost off topic.

If we can buy an album that has the full datastream on it and can also buy/download a compressed version that has just 10% of the data, what price differential should apply to the lossy compressed version cf the full version?

Let's take an example.
a 16bit CD has about 600MB on it.
A 24bit DVDa has about 4GB on it.
If the DVDa were compressed down to 600MB, would we pay the same price for it as the CD?

If the CD is compressed to 40MB, then what is a fair price for the 40MB?
In my view 600MB is worth £10.
40Mb is worth £1 and that leaves each track at about 8pence (16cents).

This may be of interest

To me any system that records and something is audibly missing due to the limitation of the method/system used is lossy.ie CD.

I record in varying systems.I know when something is missing ie lost.Sony and Philips dont argue whether CD is a perfect system any more.The only people who do are hi end (expensive) CD manufacturers.

why not just say inadequate ?

http://en.wikipedia.org/wiki/Lossy

from the above lossy refers to compressing data

in other words "lossy" is whatever happens after the signal has been digitized and is not a measure of quantization error.

i see no point in inventing your own personal definitions when there is nothing wrong with existing ones.

i understand your point about CD format (16bit 44khz) but i think this issue is complicated enough that you do not need to deliberately confuse it further.
