etc.

(seite = site / page)



it is a summary of German diploma work, written 1998, so it should be independent from companies like Zoony etc.

It was quite a good reading, I hope, somebody of the germans could translate important things, sorry, I have no time.

So, the result was:




44.1 kHz, 16 bit:

they used Tascam-DAT-Recorder DA-30 MKII as reference for CD standard, 44.1/16.

They tell, that this was picked out very clearly from the majority.

(btw, they show a graph, that says, that 16 bit has in mid frequency range a noise level, which is higher than our hearing abilities. very interesting !)

so, 44.1/16 is not sufficient.






48 kHz, 24 bit

one DAC was preferred over analogue original, but why could not be figured out. So there was difference but which ?

another DAC was able to reproduce the analogue original as best DAC of all tested, better than all the 96 kHz DACs !!!!!

in blind test it was 50/50 %, so this DAC could not be distinguihsed from original source.



96 kHz:

Dacs had worse performance than the 48 khZ ones.
but some were "beta-versions...".



Look at the graphs, especially site 9.

Sorry for this short post, but I think, it may interest you...

Hey, hey, people... stop, please!!! Sometimes I just wonder like Alice in the Wonderland rolleyes.gif what is being discussed here... Music stays completely aside, the talk si about something what almost nobody really needs. Just remember the old days back in 1955 to 1965 and excellent jazz recordings especially from Rudy van Gelder era done just with two mics in his living room on 2- (or 3-) track machines... The songs being recorded in one take, maybe some takes were made for each song and the whole album was made within a days (very often in one or two...) The recordings (be it on LP or later a CD re-issue) have excellent quality, maybe with higher noise but who really concerns? This is what really matters, real music in the real world... not these academical extracts... laugh.gif
