I2S different LRLCK/BCLK

Hello,

 

I using the DSP ADAU1701, and I have the following questions:

1. Using the I2S input interface, if I reproduce an audio file with a sample rate of 96kHz/24 bit stereo, the LRCLK of audio source is 96kHz, the DSP is set to 48kHz, is there a missmatching? And viceversa if the DSP is set to 96kHz and I reproduce an audio file with a sample rate of 44.1kHz/16bit stereo?

 

2. Using the I2S input interface, if I have two different audio sources with two different LRCLK/BCLK, how I can manage this issue? I would like to connect the audio sources on SDATA IN0 and SDATA IN1

 

Thank you in advanced

 

Fabrizio
