Hello every,

I am using a audio codec that records sound from a line in and output an I2S digital stereo signal.

I have the absolute restriction to use this specific audio codec and I want to transmit the data back to the computer as an USB Audio Class device. Do you know how to do this operation ? What part should I use to do the conversion of digital format ? I come to you because I couldn't find doc about this specific case on the internet...

Thank you in advance !

 

This is one of the closely guarded secrets of the high end audio device business. I know how to do this but I can't tell you how it's done. I'd lose my membership card.

 

Haha I see.. not even a little hint ?

Well if you have an FPGA and a USB Audio chip you should be able to work it out
