Hallo,
Have anybody another tip to run these configuration at 96khz? At 48khz anithing works fine.

Booth IRQ 9- first and last PCI
no more other PCI- Cards
Asus p4p 8ooe deluxe Raid Array HDD
2,8 P4
1GB Ram
400 Watt Netzteil
all changes PCI Latency Timet tryed

I know the Problem is known, but maybe someone have new informations.....
Is it the same problem when I connect two Pulsar2 boards? Then the only solution is get a second Pulsar2 to have more cheap dsp power and i/os ?

Thank you very much for answering

a second generation card instead of the p1 might help.

there are some plugins that may not work well at 96khz such as minimax whose filters are already oversampled.

once again, i question the wisdom of high sample rates when the target is 44.1khz on a cd. downsampling will destroy any benefits of 96khz and depending on how the downsampling is done, the final result may be worse than being at 44.1khz from the start.

also, computer resources in general will be maxed out much quicker(hd space, track count, dsp usage). you won't get nearly as much work done, in fact, less than half....

high sample rates are how gear is sold to unsuspecting consumers...at any rate(pun), sorry for sounding so cranky...

Thank you for these interesting facts. I tryed some n1084-eqing with 44,1 and 96 khz to an original 44,1 khz track. In the end of the cd the track with the 96khz eq-ing sounds a little bit better/bigger.
Maybe you´re right. Its true. The difference makes the AD/DA- and all the signalprocessing quality! not the Samplerate first. So creamware sound is creamware sound! But why not this little bit more. And dont forget at mixing-process the overtones/harmonies...some RETURNS to the range of 20 hz - 20 khz.
mp3-listening makes me feeling bad, 96khz makes "boom", cd sounds cold (I don´t have a rme adi2)... if the samplerate setting have a "dsd"-button I would use it.(But then I`ve to build some new pci slots at my motherboard for moooore creamware-cards...)

Yeah, 96k is ludicrous. There is barely any benefit. It takes over twice as many computations on your computer and the DSPs when you work at 96 instead of 44.1.

Think of it this way. If you work at that rate, it's like turning a Scope Professional card at 96khz INTO a Scope Project card at 44.1khz.

Thank you very much for the answer.

In the last time since I have the second card I worked with 48 khz...The sound is goood, indeed. The computer has an easy work, the creamware dsps too.
I think its my subjective feeling and HEARING what I miss at 48 khz. I get accustomed to that. Its absolute ok.

But when I switch to 96 khz back with 1 card (...3 -Hardwareprofile- Pulsar1, Pulsar2, booth...dont know the english word)I hear that smooth mellow bright sound...

I have no outboard fx-equipment. Thats the thing...All fx and mixing makes the cream-ware. If I had 10000s Eur tube eqs, compressors, 808, ad/da, microphones and so on I think it makes no difference wich samplerate to take...

So I´ll try to mix my tracks at 48 khz and mastering at 96 khz.
Also I´ll try to mastering at 48 khz next time.

If there is absulute no difference between the tracks I´ll post it! - Don´t know.

Have a nice day, be careFULL to your ears...
...maybe I become a "Goldene Schallplatte" whith 48khz-producing I will post it...

your cds will be at 44.1khz. that is where you should work. downsampling produces aliasing.

DVD Audio is 96kHz

I recorded 3 tracks 96kHz 32bit (back in 2003) just as a test.
I used a Luna Card (Powersampler) with a Luna 24/96 box.
No problem with recording or playback, but i can't remember if i used any Scope effects.

As i remember, you can't record 96kHz with 14 or 15 DSP cards.

good testing :smile:

some dvds are at 96k. most commercial releases are at 44.1 or 48khz. 96k is all about marketing, but if you want to work there, it's ok by me. it sounds great, wastes resources. heck, most people listen to mp3s these days....

mm i can record/playback fine at 96khz with a 15-DSP board.

i find moste of the dvd's i have checked are using 48kHz samplerate.

96kHz seem to be hype, and as pointed out, cd's are 44.1kHz for now. As for listening 44.1kHz or 48kHz are good enough.

But its realy a diffrent in the producing and mastringstage to have a bit higher samplerate then 44.1kHz, i haven't used 96kHz too much to say its worth the cpu/dsp drain, but i know its audiable to move from 44.1kHz to 48Khz.. and then its up to the dithering to get the best out of it when rendering down to 16bit/44.1kHz. but thats the last stage of the production (should be).

Movies on DVD's are 48k.
DVD-Audio might be 96k

That's good, but as i remember, someone had
problems doing that, but it might be other problem/conficts than the scope.
There is a tread here somewhere.

Are the 1st generation Pulsar/Scope cards even capable of going 96 Khz?
I have a PowerPulsar card (2nd generation I assume) with 2 1st generation Pulsar cards and it always seem to give me error message when I even attempt to go 96 Khz.

And yes, the number games played by the industry...I remember how they often try to pre-steer listeners' perception in their favour...

Yes.
But in my experience I've noticed that the OS is very important. For example some time ago I've got both Win2000 and WinXp installed at the same time in the same machine. Win2k doesn't handle 96kHz but WinXp does. In my system I've installed a P1 and a P2. The strange thing is that after a few time I've got to reinstall everything and I've choosed WinXp for that reason. To achive the 96Khz I've got to swap the card order changing the cset.ini.
This behaviour is strange, indeed, but maybe is caused by the combination of a P1 and a P2 ( it's discussed somewhere here in the forum that it's no an optimal solution).
