 |
|
I just picked up a Soundblaster Audigy on ebay for a snip. It was local and I
picked it up today saving a further £2 or so.
It's just the bare card though and I can't check which model it is on Creative's
site to download the right manual. Lots of Audigy models but none seem to match
this one.
The model number is SB0090 and it has the 'SB'1394 interface too. On the card
etched in the pcb foil is "Audigy SB1394 EAX Advanced HD".
The card looks like this one...

Ideas ? How good a performer is it really btw ?

There are versions of Audigy that don't resample. But resampling is
not a problem with modern CPU, one can do it perfectly in software.
Re-sampling is NOT the same as changing the sampling rate.
Changing the sampling rate is, as you say, a software function.
|
I'm using the word "resampling" with meaning like in Wikipedia:
http://en.wikipedia.org/wiki/Resampling
There is no fault in resampling itself, except that Audigy
implementation is not good. Reverting to external software methods
improves playback quality.
| Quote: | OTOH, re-sampling appears to involve going from digital to
analog and then back to digital for no compelling reason.
I just don't trust consumer-goods vendors like Creative to
do this right.
|
No, there is no such a process on Audigy.
Probably you are thinking about digital sample rate conversion to
48kHz that is executed even for 48kHz input. Fortunatly this can be
omited.

I think many of us know that.
| Quote: | Changing the sampling rate is, as you say, a software

|
Sample rate conversion is done in hardware or software.
| Quote: | OTOH, re-sampling appears to involve going from digital to

|
Sample rate conversion is almost always done 100% in the digital domain. I
know of no modern exceptions, so lets go with 100.00%.

|
They started out doing it not well at all in the Live!, and slowly worked
their way out of it. |

No. It can all be done in DSP.
The issue is not how it *can* be done, but how it was done
by "Creative".
It was always done in the digital domain. Cheaper that way.

What was so flawed about their original method Arny ?

I'm well aware of that thanks. It is however somewhat
superior to many classic soundcard implementations
though.
As gutter runoff is "somewhat superior" to sewage.
Damned by feint praise?
For £3.19 ($6.40) I'm really not complaining. I needed
another sound card anyway. I enjoy getting a bargain too.

If you want a real thrill, loop some of your favorite music through your
Audigy and re-record it, and see how many times you have to do this in
cascade until you can reliabily hear a difference with one of the PCABX
programs out there. Be sure to pay attention to level-matching. I suspect
the number is >1. |

The original method audibly degraded both dynamic range and bandwidth.
Download the files from this page and listen for yourself with one of the
many fine DBT test coordination software out there - right now I use this
one: http://www.kikeg.arrakis.es/winabx/ . Be sure to turn off the
nonstandard test option.
Looking around for user reports about my test files - it appears that the
french horn sample is particuarly revealatory.

One of many.
Not nearly as yucky as the earlier Live! cards where the resampling was done
incompetently. Eventually Creative were bludgeoned into at least doing the
resampling semi-competently. I may have had a hand in the bludgeon party.

They are branded eMu. |
