Loop back audio output to microphone input in XP-USB-MIC-UF216 board

Post by bhanuprakashbv »

Hi,

I have some questions related to XMOS microphone array board. Please find below.

1.Inside XUF216, is it possible to synchronize the reading of microphone sample with sample played out to DAC?
2.We want to make sure that the output buffer to DAC and input from ADC are in sync with each other and they are operating on same clock.

Do you have this configuration already supported ?

As per attached figure: xCORE Microphone Array block diagram,we would want left and right channels going to DAC to be also available as microphone inputs MIC5 and MIC6.

For some reason if you don’t support in this board ,do you have another board which can support this

Thanks,
Bhanu
