Audio to I2S for DAC Testing.

[diyiggy]

NO! They will not ship any order to the UK unless the total is over 161euros, even though they do not have to charge vat on exports. I've never come across such a stupid policy and their claims this is due to Brexit is nonsense. UK customs will collect UK vat if it is due (not normally on low value (<£39) items)

LOL, tried to purchase something today and an "Error" occured ! Lol twice because now Audiophonics seems in the Frexit as well ! Uh !

For testing my various diy dacs I have used CD test discs in the past.
Ideally an audio to I2S interface would bypass this and allow direct audio from a sig gen to the dacs I2S (PCM)
i found this one:-

or this one maybe a better choice:

Any views?

I have a 8782 from audiophonics. I thought I could connect it to the I2S interface of a MCU. However, I could not get it to work. The audiophonics guy was unhelpful and seemed to know nothing about these unbranded things from China. I could find no evidence that this thing was actually useful. There is no test case to demonstrate it's operation.

I use the Amazon one because Audiophonics wouldn't ship orders below £160 to the UK, blaming Brexit.

It works well via spdif and then a standard Dir90001 spdif to i2S receiver connects it to my dac.

Trying to use ADC to I2S on WM8782 + SA9227 USB interface and this is what I get with floating input, any suggestions about high frequency peaks from WM8782 ? Powered by LT3042 with linear supply. Now it works without shielding, but I think it is not RF from PC at so low frequency.

Why are you floating the inputs? They may tend to act like antennas.

 

[diyiggy]

So guys, have you a preference in those cheap off shelves DACs between ES9039e2m and ak4899qms ?

 

[Markw4]

Do those part numbers exist?

 

[diyiggy]

Well, the consumers ones just before rhe top line...

Agree, my stupid act
