Sonar doesn't do 88.2 kHz sampling?

I downloaded the 2.0 demo version, and it appears not. Since my A/D converter has that native capability, and my end goal is to mix to 16-bit/44.1 kHz CD format, I thought 88.2 would be a better place to start than 96. ??

Also, the demo didn't like my soundcard at all... M-Audio Delta Dio 2496. It detected the card, and then gave a list of driver components that it said were "not compatible with this audio format or were already in use." I couldn't get any input from the soundcard, although I know the signal chain is working because I have already tracked some "quick and dirty" tests, and was able to record and playback just fine with n-Track demo.

?? I thought Sonar was going to be the one... perhaps not. :(
 
...maybe that's the limitation of the demo version. I've got mine works well, and never heard this complaint before... or, do I miss something ? :confused:
 
Limitation is the 88.2 kHz sampling option, or the apparent lack of agreement with my soundcard? Before I go researching a lot on driver compatibility with the Delta Dio card, I'd like to know if the sampling option exists or not.

Can you check in your full version and see if you can set it to 88.2 kHz 24 bit sampling?
 
No, 88.2K is not an available sampling rate with Sonar. 96K is.

However, if your ultimate destination is CD, I would not recommend recording at that rate anyway (although it is probably a better choice than 96). Resampling will likely hurt the project more than recording at 88.2 will help it. Conventional wisdom is that you really should only use higher sampling rates when your destination medium supports it (e.g., DVD).

Suggest you consider recording at 44.1K and 24 bits.

(Also, btw, Sonar has no resampling capability, either. It can convert 24 bit rate to 16 bits - although I would suggest using other programs to do that as well, since Sonar's dithering algorithm ain't the best.)
 
Yup, I've checked it, it's 96K. BTW, Dachay got the point, why would you take 88,2kHz if your medium's gonna be regular CD ? I mean, all the benefit of higher sampling rate will finally squezed into half anyway... 24 bit or 16 will be just fine. But if you like the first option, suite yourself. ;)
 
Well, here's my reasoning: when sampling at 44.1 kHz the aliasing filter has to be pretty agressive to allow audible frequencies up to ~20 kHz to pass. When the Nyquist limit is moved up to ~40 kHz the filtering is (1) much smoother and less agressive and (2) out of the audible frequency range.

Downsampling from 88.2 kHz to 44.1 kHz is a "clean" process with an even coversion ration, so there shouldn't be any resulting artifacting. You're essentially just dropping every other sampling point.

Does that make any sense?
 
I agree that 88.2 -> 44.1 is a cleaner conversion than from 96. But I still feel you would get better results starting at 44.1 and skipping the downsampling (assuming the destination is 44.1).

However, it sounds like you knowest where you leapith, so have at it.

(Unfortunately, it still doesn't change the fact that Sonar won't do 88.2 :) )
 
Yeah, I see you make sense Bigus Dickus. That I will learn to see the result in my ears... :) BTW, did you do the Wave profiler ? how's the score of your curent card ?
 
i agree with BD.

doing all of the sound processing (individual track dynamics and fx, and main bus mastering dynamics and fx) in 88.1khz then re-sampling down to 44.1 is the better from a technological standpoint. the same way that recording in 24bit and then dithering down to 16bit makes sense.

let's say i want to create an avatar for my HR icon, but i want to take the original image and add processing to it, i'm not going to try to take the picture at the same resolution as the avatar size. i'm going to take a great picture, add my processing, and then resize the picture to avatar size. digital audio is the same in that regard as digital video.

when re-sampling from 88.2 to 44.1 you are in effect taking every other sample.
