24-Bit / 48kHz or 96kHz
« on: February 18, 2012, 11:19:08 AM »
Hey everyone.

Just picked up a good quality 32GB microSDHC card the other day so I got to thinking: now that I have over 30 hours available at 24/48 and over 15 hours at 24/96, I'm wondering if I should record at 24/96 going forward?  I've always said (and thought) that there is little-to-no difference or benefit on using 96 except that you're "wasting" double the disk space.   Now that I have the ability (and space), I'm just wondering if I should go 24/96 going forward or just stick with 24/48. 

Gear being used is either DPA-4061's or CA-14 cards > Church Audio ST-9100 v4.4 Preamp or CA-Ugly Preamp > Sony M10.

Just curious as to what people here think.  TIA.

I can't tell the difference between 24/48 and 24/96. I record 24/48 to save HD space.

 It's a matter of preference, I run 24/96. You'll get a different opinion depending on who you talk to. The best thing you can do for yourself is try it, and then make YOUR decision. Some say they hear the difference, some don't.

I probably can't hear a difference, maybe others can.  So if you're going to record it and share it, you might as well make the best possible recording you can, IMO.  Although it does take more space on whatever storage device you use, and takes longer to process with your editing software.

I'll echo what others have said here and tell you to try it for yourself and see if you can hear the difference.  Personally, I cannot so I always record at 24/48.  DVD quality audio is more than good enough for my purposes.

I think you have to balance these 3 considerations - hearing the diff, available space, and processing time - and make the decision based on that...  I'm pretty lazy, so I usually just do 24/48, if I ever get out to tape...

I'll record in 24/96 in most instances unless I have space concerns with the SD card. My theroy is that since I can listen to the recording in 24/96 I might as well go for the highest resolution my playback system will permit. If I was going to dither/resample back to 16/44 then I dont see the point.

What about file size limit? That would be another reason to stick with 24/48, in my opinion. Even though most of out decks start new files seamlessly (I assume), I don't like that happening in the middle of a song.

I'll chime in with a bit more information -- space isn't a limitation for me as 32GB is plenty.  I have a system capable of playing back 24/96 with ease.  And for processing time, I'm running an i7-2670qm laptop with 8GB of RAM and a VERY FAST SSD so it's less of a concern as well.   

I also can hear a considerable difference with studio recordings at 24/96 vs. 24 or 16/48 or 44.  I guess the main test will be to just run a show or two at 24/96 and see.  Thanks for the feedback so far, guys.

 The better quality playback system you use, the better chance you'll have hearing any audible differences.

for recording loud amplified bands 96 khz makes no sense or you know the stacks can run up to 40 khz frequency response.  ;D

full acoustic or recording nature, or for SBD pulls it would be ok.

When doing analysis I always recommend high-quality headphones, it is *much* easier to spot differences when environmental noise is removed.  Best of all, they are much less expensive than high-quality speakers :)
I agree.

The difference between 44.1 and 48 is larger than the difference between 48 and any higher rate, within a 20kHz bandwidth.  So, first I would test to see if you can hear the difference between those two rates.

QFT

I did this years ago, and do it every time I upgrade my gear (either playback or ADC) and I can hear clipping more then I can hear the difference between 44.1 and 48k on good equipment when doing an actual ABX test.

I agree.

Agreed also. Well, not sure about the cost issue, but the rest of the comment is spot on.

Run the highest resolution you can for mastering purposes. Regardless if you can hear it or not, someone else might.
Hell I plan on running 192/24 now that cards have come down in price and I because I can. Do it for the future :p

thats assuming your converters work as well at 192khz as they do at 44.1 or 48.

Run the highest resolution you can for mastering purposes. Regardless if you can hear it or not, someone else might.

that's also assuming that what you are capturing is actually valuable. I have a bunch of >48k recordings which I made that showed the mic I was using had a 30db spike at around 35khz. I can't hear it, but my cats might be able to... Not sure they appreciate it though.
