usb to I2S audio platform

With great honor, we have received a request from our Swiss customer to design his new USB to I2S board for Audio Applications.
This company is leader with producing high-performance professional audio systems.
This board has the form factor of a Raspberry Hat, so it can be conveniently connected to the 40pin connector of the Raspberry boards: once connected to a DAC board (this customer already sell Dac board with Raspberry form factor), the whole solution would represents a stand alone sound card, without using a Raspberry for this task.
For this project we used a chipset from XMOS (XCORE 200) that helped us to realize this project by owning both the USB device and the I2S interface.
