Asio 24/48 Recording with Audigy2 ZS Asio Drivers

carnival · Apr 17, 2006, 03:34 PM

I don't know how it happens, but i'm able to record at 24/48 using the SB Audigy 2 SZ Asio driver in Cubase SX2. I can record at 16/96 either, using the Audigy 2 Zs 24/96 Asio driver. Wasn't it supposed to be fixed at 16/48 and 24/96?

I've checked the recorded audio files in the Pool and they really are 24/48 files (or 16/96). Does anyone know anything about this?

I'm using the latest creative official drivers set with the bundled software in the install cd.

Havent used that prog so i dunno. ASIO 96/24 in Adobe Audition works great though. Make sure in Creative audio console you set 96 khz. Dunno. I bet somewhere you didn't configure something. In Cubase see options for sound hardware to make sure you have your ASIO set to 96/24

you can record at any bit resolution/sample rate, however the data you are recording will be dithered/resampled depending on the incoming bit resolution/samplerate

Thanks for the replies. I can record at 16/48, 24/48, 16/96 and 24/96 with creative asio and asio 2 drivers (so i guess there's no problem with the drivers, i just didn't explain well in the first post).
If i choose the 24/48 incoming bit resolution/samplerate and then record some audio tracks, when i check the pool the recorded files (guitar, voice...) are 24 bit/ 48 khz files. Were they actually resampled? How can i check this?

In the past, when i used the creative asio driver i couldn't choose the 24/48 configuration in cubase sx because the asio driver was locked at 16/48. But now it seems to accept this combination. The advantage of this is that i have all the inputs available in the vst connections pannel (the same as 16/48) and all audio is 24 bit.

you might want to check each file with an analyzer that can actually prove the wave form is really 24bit, not just 16bit padded to 24 bit

Can you tell me about a good software to do that? Thanks.

dj_stick is right with this - you can record only 16-bit/48kHz and 24-bit/96kHz w/ your Audigy 2 Zs card using Creative bundled ASIO drivers. If you just read the Cubase SX manual you'll maybe understand some basic facts you're missing now.

Note: I have Audigy 2 here and yes, I can record 16-/24-bit and even 32-bit (float) resolution /48 kHz files using both Creative ASIO drivers
--> true audio resolution is 16-bit/48 kHz (because the card can't operate at any other resolution w/ ASIO),
--> audio file resolution is the selected resolution (16-bit + padded w/ 8 or 16 '0' 's).

Ok. So the files are actually resampled by the soundcard. Should i record at 32 bit float or 24 bit and then dither the final song to 16 bit? Or should i use the 16 bit depth since the beginning to record the tracks? I mean, what's the best quality choice? Thanks

I think it's best if you try to find the best (audible) result by comparing the results got from different bit-depth/SR settings.

By the results from RMAA test, the best result can be got when bit-depth is set to 24 and the samplerate to 96 kHz (this w/ WDM, MME, DS drivers).

As you might already know, Creative cards (excluding X-Fi's in Creation mode) are not very good for recording (the well known resampling 'issue'). If this 'issue' is (still) the case w/ A2 Zs (as suspected on article) , you maybe get about the same end-result quality by record using 16-bit/48 kHz (only SRC is then needed to get the CD quality) as you would get w/ 24/96 (dither/SRC needed to get CD quality). That's why I suggest the self made comparison.

Also, the conversion process may change the data quite a bit, if you don't have well made software to do the job:
- http://src.infinitewave.ca/
- http://xserve1.bias-inc.com:16080/pr...o5/resampling/
& - http://xserve1.bias-inc.com:16080/pr...WhitePaper.pdf

IMO, if you're serious w/ recording --> get some more pro card instead of Creative consumer series cards (there are many pro classified cards < 150$ --> from M-Audio, E-MU, ESI, etc.).

Thanks a lot for the reply. I'll try different settings and compare the results as suggested.
