Hello,
can we arrange some details here about "recording". Do you mean creating a file? If so what kind of data it should contain, sample rate, raw or compressed, etc.
Please clarify, thanks.

when I connect mic in and line in, I want to receive and see the raw data( I2S or TDM data/PCM data etc) or compressed data(Audio waveform data).
Because I have to coding and processing from these data. (44.1 or 48kHz and 16 or 32bit ,high quility for digital processing better^^)
Besides, I want to know all kinds of the audio data format from MIc in and Line in through" MCASP_Audio_evmOMAPL137_c674xExampleProject"
ex)Dout in audio codec(3106)

Hello,
you mentioned "MCASP_Audio_evmOMAPL137_c674xExampleProject" from "pdk_omapl137_1_0_7" but I am not finding it.
Can you specify which source files are included in this project so I can inspect them and answer the
"Besides, I want to know all kinds of the audio data format from MIc in and Line in through"
part of your question.
