From sound source, there are several sample rates input to ADAU1701 through IIS. Such as 44.1K, 48K, 96K.... Can it work? I set the DSP working at 44.1K only.
Unfortunately this would be possible only by including an asynchronous sample rate converter (ASRC) in your system. The AD1895 may be a good choice since it goes up to 192KHz. By examining its data sheet, you'll see the complexity needed to properly translate sample rates across sources and systems.
Several SigmaDSPs include built-in ASRCs, but these omit one or more ADAU1701 features you may be using (such as built-in ADCs, GPIO, and/or self-boot).
Thanks Bob, I will read AD1895 datasheet, hope it will help.
