adau1701 downsampling
How can I realize down sampling in ADAU1701, I know ADAU145X contains this module, we can use it directly.
There is no this moudle in adau1701,so is there another way to get the same result?

Hello xiaobai1122,
The 1701 is a Sigma100 core. The 1452 is a sigma300 core. It is two generations newer and we made many improvements and added features in the core. The sigma100 core does not have interrupts and cannot process audio at different rates. It is a pure stream deterministic type of processor. So it is impossible to downsample in the core. The Sigma200 core has one interrupt for the basic stream but it also cannot process audio at different rates. This feature was made possible in the Sigma300 core so you have to use the ADAU1452 or the ADAU1467 family of processors to get this feature.
