Acko,
What sort of editing do you want to do? There are many pro / semi pro packages most work with Asio drivers and some are quite inexpensive.
But I'm guessing you are referring to software that manages USB IP and talks to editing or DAW package.
I'm interested in at least 1 but I'd like multi channel capability probably with clock synchronization.
Did you receive my PM?
cheers
Terry
PM replied -thanks
Yes, recording live stream seems to take us the realm of Digital Audio Workstation (DAW) and related software that captures from I2S-USB hardware. Still looking around...
Is there any I2S -> USB boards that could be hooked on to this board to save data on a laptop?
This looks suitable:
miniStreamer | MiniDSP
and GoldWave Audio Capture/Editor Software

The Mini DSP USB devices look OK however the clocking is not up to par. I think they need to upgrade the clocking to
a VHQ low phase noise XO and I'm not sure this is possible esily. Maybe you can look into it.
There is absolutely no point using something like the ESS ADC without careful consideration to clocking.

It depends how much you want to spend and the complexity of editing.
Personally I will be using Reaper, a fully fledged DAW that runs 64 bit
internal audio path, will handle any sample rate, 32 bit word lengths and is a
professional quality recording package. It is $60 for non pro users which is
an absolute bargain for the power of the package.
However this is probably above the requirements of most people here.

60$? A bargain indeed. Is it easy to handle or too complex for the ordinary user (who knows what DAW is 😀)?

DAW = digital audio workstation.
It is a pretty complex, full multi track recording package. You need to know
quite a bit about recording / editing techniques to get the most out of it.
This would take considerable commitment to learn. I'm into recording and design
of 'front end' hardware, so right up my alley but probably overkill for most here.

Acko,
Are you planning stereo (124dB) or dual Mono operation to get full 127dB DR?
Does the 9102 have inbuilt ASRC as per the DAC?
cheers

Interesting Project,
Direct recording to SSD or SD would be great for location recording. Sure it would involve custom programming and would make it harder to implement but it would be very atractive to many...including me.
Following this thread with expectation.
(Edit: Maybe interfacing the ADC to a Beagle Bone board with a touch screen cape would be a perfect way to build up such system...)

Acko, I'm almost on the list, just want to understand that I can master the task to make what I want. A small, hyper quality 2ch (or more) field recording thingy. zenelectro seem to be a good companion to have onboard the project. Lets nail the clock solution. Including consideration for mechanical vibration and power feeding quality etc.
I form factor was really long and small, I would like to built it into the mic(s) for shortest possible analog signal paths and long power/digi connections.
Then I dream about an optional clock distribution from a central point, with clocks mechanically isolated, using (femto-)opto in a synchronous fashion without any PLL in the ADC in the mic(s).

Thanks for all the feedback and comments.
Actually before project creep sets in I have gone ahead with the ADC board layout using ES9102. Will preview soon and discuss suitability before going to print. There is a fair amount of complexity so decided will be a fully populated board with the desired interfaces and options for a general purpose module to start with.
Yes, there are lots of potential applications - hi-res digital mastering or remastering vinyl @ 384k/32bit native sampling, hd live recording etc!

Please crosspost on your national forums to get more attention to this.

What sort of analog front end are you thinking Acko?
If you want to run ESS ADC in mono mode and get close to the possible
127dB DR (A weighted) that is no trivial task.
Not that such a huge DR is the only important focus. IMO anything over
120dB and you are doing pretty well.
cheers
To get a clean clock you could consider the MiniDSP USBStreamer instead of the miniStreamer. And add an interface like the one I have described here:
http://www.diyaudio.com/forums/digital-source/244042-master-clock-isolator-minidsp-usbstreamer-3.html#post3751341
This would allow you to use the cleanest clock that you can find. And if needed it would provide 8 channels instead of 2.

Thanks Terry, couldn't agree more. I we pare back then the performance drops accordingly. I will be focusing on the ADC module only initially and other specialised modules to match in future. The preview shows the concept design for a 2CH board and as you can see with all the power supply requirements, etc puts the level of complexity right up to that of the 9018 DACs. Inputs are line level and requires specialised buffers to drive it as its immediate front end. Mono and multi-channel mode are even more involved with external controller development.

does this ADC need software register programming for the selection of the output bit depth/sample rate or it can be done also in hardware mode?

Hardware mode can be setup for different sample rates but bit depth seems to be fixed at 24/32 bits. Will check again and advise.

Very interesting! Thanks JensH 🙂

ADC is Hi-Res full 32bits in I2S mode and full 24bits in spdif mode.
In hardware mode only I2S is available. Spdif disabled
Sample rates can be selected in hardware mode: 48k, 96k, 192k and 384k (running on a 49.152MHz MCK). If using 45.1584Mhz then 44.1k based Fs possible
No RIAA filters enabled
No mono mode
No multi-channel
