Wich program do you recommend for hard disk recording?

Ok, I've made some testing (I use Hyperos 2002, few Windows OS on the same machine, it is a really great soft for taking the best of a system).

Recording with Samplitude works perfectly with SFP and Creamware's 24 bit WDM-wave drivers in Windows 98.
Samplitude can communicate with Creamware's card at 32 bit, under Windows 98. I recorded 32bit 48kHz audio files and it was perfect. In Windows 98.

In Windows XP, recording 24bit files does crap with the Creamware's 24bit WDM-wave drivers with: Samplitude, Sonic Foundry Acid, and Wavelab.
The only way I can properly record audio files at 24bit in XP is with the Creamware's ASIO drivers.
Other users told me that they have the same problem in XP with Creamware's SFP 3.1a

But remember: in Windows 98, Samplitude can communicates with SFP at 32bit (you have to go on Samplitude's preferences to choose 32bit) and makes 32bit recordings. It couldn't be better.

For the issues with Creamware's WDM-wave drivers and Windows XP, we'll see what's going on with the next update SFP 3.1b (coming very soon)

Hi Grok, could you explain what happened recording 24bits with Wavelab? Cuz i use wavelab, and i seem able to record in 24bits perfectly? Is it only allowing the 24bits record but in reality it is in 16bits or what? How can i check this?

Hi Marcuspoppus, I forgot to wrote that 24 bit recording works fine with SFP and Wavelab and ASIO drivers.

With Wavelab, SFP, Creamware's WDM-wave drivers and Windows XP, I had bad and unusable 24bit recordings, with crackles. Other users had reporting me the same.
This issue doesn't exist in Windows98.

So I would be happy to know that you have a XP/SFP3.1a/Wavelab system properly working with Creamware's WDM-wave drivers?

Hi Grok,
Are you using the Demo of Samplitude, cause there are known issues with WDM support. It was fixed with a patch, but that wont work for the demo only the full ver.

Hi Davo, I use the full version.
Ok, I'll check the demo version.

Yes Grok, i really use WinXP Pro, SFP3.1a, and WaveLab4 (4.0c i think?)

And i'm able to record/playback using WDM (wav driver) without any problems so far. What i'm curious is how would i know that it is really 24bits wavs i'm recording? Isn't it possible that the 24bits driver itself work, but working in 16bits mode? Because so many people are saying that's impossible, 24bits wdm doesn't work etc... And that i'm using it and it seems to work...

Ok, you mean that it could be "real false" 24bit *.wav files with a 16 bit resolution?

marcuspocus · Post by **marcuspocus** » Mon Jul 22, 2002 4:25 pm

That is what i'm asking you in fact, cuz i DON'T know how to check this. But again, my wavelab is working perfectly here, and really detect the 24bits wav driver.

this may be a stupid question but wouldn't checking the size of the file tell you whether it's 24 or 16 bits?

Wavelab has a "bit scope" that will tell you precisely how many bits are active.
So you'll need to record something that fades in from -oo to 0dB. That should do the trick...

A short test with Samplitude 6.04 + Win98micro + SFP3.1a:

recording: 16 simultaneous 32bit 48kHz stereo tracks (it is the maximum available in Win98), when listening to 16 others 32bit 48kHz stereo tracks. OK.

playback: 32 simultaneous 32bit 48kHz stereo tracks. OK with the VIP buffer set to 4000.

Hardware used for this test: Athlon 700MHz + 768MB PC100 SDRam + Ultra DMA 66

Conclusion: I didn't push the hardware to the limits. It shows the capacities of Samplitude 6.04.
