Default digidesign 192i/o 48k vs 96k

i just recorded a whole project on the digi 192 in 48k by accident!!
i meant to record @ 96k
an engineer in the room told me he honestly couldn't tell the difference
he thought we were tracking @ 96 the whole time..

and i diddnt catch the mistake untill we were done tracking..

ive seen lots of debates on this in the past but this was the perfect blind test!

does anyone think 48k and 96k is that different on a digi 192, as far as quality goes?
im bouncing down to cd after mixed and mastered..

AFAIK, all Digi interfaces cut the audio spectrum to 20Hz-20kHz so the sampling rate does not really matter as long as there are no audible artifacts on the top end. And yes, the 192 is that good, the difference (if any) should be very minor.

If you on the other hand want to be mixing at 96k, just upsample and be done with it.

no, the filters are in different places for the different sample rates. i read something that ed meitner [one of the designers, apparently] posted a while back to the effect that the 192 i/o interfaces were "optimized" in some way for 192kHz. most people probably use them at 96kHz to get a bigger track count though.

192 is very limited in the track count available

and some plugs don't like it and you can't use too many plugs with it

i use 88.2 most of the time

i just dig it

now here come the buts:

i've done a few cool cds on 96

but many many cds on 88.2 for a long time now

but 192 sound fantastic on acoustic guitar, solo piano, classical anything

but the times you really notice it is with only one or 2 inst in the mix.

I usually record on the 192 i/o at 48k, which allows me to record rock and roll and hip hop at 64 voices for 2 DSP's in PT8. Last week I tracked a more bluegrass-rock record at 88.2 and was only able to get 48 voices on those 2 DSP's. It sounded great. I also recorded a jazz record a few months ago at 96k in PT 7.4 and then mixed it in PT8 (about 20 tracks total in the sessions) and it was wonderful.

But great talent, mic placement and model number selection all trump the sample rate.

44.1 all of the time. Record after record after record.

I totally agree that great talent, great amps, well tuned drums and mic placement trump sample rate even if you think that sample rate makes a difference. Get out the blindfolds.......

GOT my soap box here...... The whole 96kHz v/s 48kHz/44.1kHz thing CAN be an advantage, but many times it just isn't IMHO. The reality is that you're actually recording at about 2.6MHz (give or take) but the converter is dropping the sampling rate down to whatever rate you're recording at. When recording with cheaper converters you're going to hear a drastic audible difference at higher sampling rates because it's less down-sampling that's taking place, that only makes logical sense. But when you have a great converter, the difference isn't that noticeable at times----sometimes it it is depending upon the content you're recording and what gear you're using to get there. For example if you're using a pair of Earthworks QTC50's to record a choir through a GML8302 into the 192I/O at 192kHz v/s other rates, monitoring through some nice oooh Focals..... yeah, you'll hear the differences there. But if you're recording some rock guitars, nah....not really...or at least not enough to make it worthwhile IMHO. The fact is that a GREAT converter at 48kHz will often out-perform a decent (and of course, a poor one) converter @ 96kHz. For example the 192I/O at 48kHz does sound better than the 96IO at 96kHz. Great converters don't sound that different between lower sampling rates like 48kHz and 96kHz because the converter chip and the analog section are doing their job.

Personally I do everything @ 24-bit/48kHz... I have great gear, I just don't warrant the additional processing needed for the 96kHz recordings with the gear I have. Sonically, the difference is so minor.... and the market I'm delivering too soooo doesn't matter. A great front-end will out-perform all the specs you can throw at it, period.

Just a quick note. The Niqust filter freq changes on the D/A section as the sample rate changes.

Try this and I think you will be amazed. Though not sure what practical application this has. But still.

Take a session that was recorded at 44.1 or 48K. For best results so you can A/B, play it back from PTs, and record it analog to another deck (as highest sample rate as you can).

Then open the same session as 96K and let PT SRC the files.

Play back the same audio... Rec to same deck (or not if you can remember what it sounded like at 44.1)

Wow.... listen to all the high end and spacial depth that just showed up! It's almost like going back to analog!

For your consideration... The reason for this is because at 44.1 the brick wall filter cuts the high end that was actually there, and mushed up the spacial info too. At least to my ears. But when up open the filter up at 96, you can hear all kinds of stuff that was totally covered up by the low pass filters set to 44.1.

Your milage may vary. But here, it's totally apparent.
