Forum: DSP USB to I2S adapter for audio transceiver

Hello, all!

I need an adapter / bridge to connect a MEMS tranceiver to my PC, to 
stream audio data for DSP purposes.

The tranceiver can either send or receive PDM data at up to 3.072mHz 
(based on clock input).

I suppose I need an I2S-USB adapter / bridge, that also comes with a 
driver software, where I can set direction, data and clock rate.

It should be fast and reliable enough to allow real-time DSP analysis on 
the PC.

Can you please recommend such a tool?

Take a look at XMOS, they have an open source implementation of USB <-> 
I2S/TDM for their chips. There are quite a few boards sold for this 
purpose, e.g.: http://jlsounds.com/i2soverusb_n.html

Nothing out-of-the-box, but it somehow looks for me like it might be 
doable with some STM32 µC e.g. by combining the Application Notes AN5027 
and AN4711.

As per my knowledge,
You need an I2S-USB adapter to connect your MEMS transceiver to your PC 
for streaming audio data ,it help to support PDM data up to 3.072 MHz 
and come with driver software to configure data direction and clock 
rates. Make sure that  this is fast and reliable enough for real-time 
DSP analysis on your PC.
