I2S to USB interface ?

[Dirk_67]

(I'm not sure if this is in the right forum section here -> please move if necessary (cause it's somehow DIY related ?))

We all know this (mostly XMOS based) USB to I2S interfaces, where you can connect your DAC of choice (or your self-built DAC)

but for ADC use, I am looking for an I2S to USB interface (so the opposite way around),

And as I would like to try to use the ADC not only for 'music conversion',
but perhaps also as a simple (hobby) measuring device for audio measurements,
I am looking for a device with the highest possible sampling frequency and bit resolution (e.g. 32bit/384kHz or even 32bit/768kHz)

the only device I found so far is this one:

XMOS XU208 32Bit 384kHz DXD DSD256 DSD reclock SPDIF USB I2S in/out PCB

No driver is needed for Windows 10/11,Mac,Linux Upto 32bit 384kHz PCM stereo in+out or DSD256(native)out NDK NZ2520SDA Ultra low phase noise oscillator Onboard FIFO Reclocked SPDIF output, 4 layer PCB No switch mode power supplies in the PCB BUY 3 GET $30 OFF! Limited time only

do you know other / better devices ?

The ADC I am using is this one (AK5572-based):

ADC AK5572 v1.2 available - nihtila.com

ADC AK5572 boards are available again, in slightly modified version 1.2. Despite a rather long list of changes there are no differences in performance and no major changes in functionality. Note that there is also v1.3 now. It is the same as v1.2 except the PCB is green. Changes are...

Design See schematics PDF at bottom of the page or schematics walkthrough in the video above. Input circuit consists of simple high-pass and low-pass filtering and input protection, followed by buffers and finally differential amplifier for pre-ADC low-pass filtering and also biasing the input...

I‘m looking exactly for the same interface to connect my CD transport via I2S to my USB DAC without downsampling the PCM or DSD signal.
Unfortunately all DDCs only provide an USB-input but not an I2S input.
Such device could be also equipped with a small DIP switch that allows to change the pin configuration of the HDMI connector to solve I2S incompatibility problem between audio sources and DACs of different vendors.
This device (interface) could be also used as a very flexible format converter to other audio formats like AES, SPDIF, USB and I2S.

Thanks for your feedback!

Hi. I am looking for an I2S to USB convertor to send my SACD/ DSD64 native/ DSD 128 native audio signals to my laptop. While searching, I observed this forum and the posts seem related. Any luck with finding one?

Thanks.
