192 kHz input for computer?

Submitted by donbarbituo on Mon, 2011-02-28 13:35

We're looking at digitizing a substantial collection of archival recordings (mostly open reel tapes). I'd like to capture at 192kHz to the computer. The USB connection of the ADC1 USB has a max. rate of 96kHz.  What hardware do I need to capture at 192kHz directly to the PC?

Many thanks.

Is your PC a laptop or a tower w/ PCI slots?

Also, what operating system are you using?

Best,

Tower with PCI/PCIe slots.

Tower with PCI/PCIe slots.  At this point, OS could be any of Windows 7, XP SP3 or the latest flavour of Ubuntu.

Thanks,

Bryan

We haven't tested this yet, but it looks like it will work for you:

ESI Juli@ Card - Simple & Affordable Digital I/O...

Submitted by gjwaudio on Wed, 2011-04-27 12:42.

Hi Bryan

You might consider the Juli@ PCI card from ESI ( http://www.esi-audio.com/products/julia/ ).  I use this interface with my ADC1/DAC1 pair, and it works flawlessly.  When I need it, 192 KHz IN/OUT is right there, without any fuss of complex software mixing.  I disable the automatic launching of Juli@'s Control Panel applet, which improves overall SQ. A desktop shortcut gets the panel running when adjustments are required.

The other nice feature about Juli@ is the analog section can be configured for -10 unbalanced -OR- +4 balanced I/O.  Even better, you can remove this section completely and what remains is a fully functional digital-only I/O card.  It depends on how far you want to take the optimisation game.

For better performance, you can bypass the breakout cable and install proper BNC connectors in the vacant holes left by removing the analog section.  Alternatively, you can fashion a secondary mounting panel (as I did here -> http://www.audioasylum.com/cgi/vt.mpl?f=pcaudio&m=27041#39956 )

Though Benchmark "has not tested this card", I can vouch for the S/PDIF output being bit-transparent (otherwise the DTS bitstream would be corrupted when fed to my HT receiver).

 I hope this helps.

Cheers,

Grant

192 kHz with Windows 7 - Use ASIO

Submitted by JohnSiau on Mon, 2012-02-13 11:14.

The following comments are from forum member Tim Leggett:  

 

"I am now able to record and playback 192 KHz from my PC using the DAC1 and ADC1." 

 

"I finally realized that it was just impossible to reliably play and record 192 using the WDM/MME drivers through the Windows Audio engine." 

 

"I found a free audio program called Kristal that records and plays flawlessly at 192/24 using the ASIO drivers and the ESI Juli@ cardthrough the card’s SPDIF input/output. Kristal will probably work with the EMU-1212M as well, but the Juli@ is very easy to use." 

 

"In case anyone asks you in the future you can tell them what I did."   

 

Thanks for your input Tim!

192 kHz with Windows 7 - ASIO Drivers Work Well

Submitted by JohnSiau on Mon, 2012-02-13 12:49.

More comments from Tim Leggett:

I could not reliably either record or play 192 Khz through the Juli@ SPDIF inputs and outputs using the WDM/MME drivers at all. This was even after I had physically removed every other audio device in my system, and all Juli@ devices were set to 192 Khz. The same issue is present if you try to record or play at 192 KHz through the analog inputs and outputs. I also had the same probelm with the EMU-1212M. I have not tried it with its ASIO drivers and Kristal. The Juli@ SPDIF i/o is failry highly regarded in the audiophile community rigth now.

There seems to be some other issue with the WDM drivers actually relaying the data to the Windows sound system at that sample rate. I was able to get a stable input only once at 192 KHz. I was never really able to playback 192 Khz through those drivers at all.

The ASIO drivers work very reliably with Kristal with very little CPU usage. I am using Windows 7 professional with SP1. Kristal is a very simple multi track audio program that once you learn is extremely easy to use. It saves individual channel wave files in the Users\\Documents\Kristal Media Files directory. I had to dig around to find its files.

One thing I wanted to tell you is I really noticed the difference with your products and the Ultralock jitter feature. I had been using a CardDeluxe sound card for the last 10 or so years and it is really not that bad.

But with your ADC1 and DAC1 comparing at 96/24 it is no contest. The lack of jitter just tightened the pitch up on everything in a very noticeable way and removed a veil of distortion. I was transferring my Tape Project tapes using my Ampex ATR-102 tape machine at 192 KHz and they are almost indistinguishable from one another. The Tape Project tapes are basically one off copies of analog master tapes and are just jaw dropping to listen to. If you are not familair and are interetsed you can read about them at www.tapeproject.com

I also have about $15K worth of turntable gear. My vinyl transfers are really benefitting from this upgrade as well. This is really where I noticed the pitch difference. When you have a device like a turntable with its speed swings coupled with a digital sampling device with its clock speed swings (jitter), sometimes they swing in opposite directions in relation to each other and you really hear the variation.

And thanks for all your help. I am really happy with this rig I have now.
