Hi Amit,

yes i already gone thru this application note.Is there any sample code available for playing the recorded audio from SD card. how about the delay? will it take more time to play from SD card since we are paralleling two SPI interface to create I2S.

Hello Aravind,

You would need to use the application note along with the sd-card example to do so. I don;'t think a sample code is there along with the application note. To account for the delay, always do use the internal SRAM as a streaming buffer.
