firstThe main device that provides BCLK and Lrck clocks.1, in the left alignment mode, the MSB can be in the bclk of the first rising edge of the following LRCLK transition.2. In right-justified mode, the LSB can transition before the last rising edge of the BCLK LRCLK.3. In i2s mode, the MSB can transition from the second rising edge of the BCLK following the lrclk of a transition.4, some sound cards also support the DSP format, the format is not part of the I2S category.LRP = 0LRP = 1Iv.

This design idea: first open a normal WAV audio file, from the 44 bytes in front of the defined file header, remove the file header definition message, placed in a file header structure. Then open the ALSA audio driver, from the file header structure to remove the sampling accuracy, the number of channels, sampling frequency three important parameters, using the
