I am having some troubles changing the frecuency sample rate. I have just found out that actually it does not change (at least for me).
I have looked for threads in the forum about it but found nothing related.
I though that just changing these #defines the sample rate changed (init1939viaSPI)
But i have a FIR filter and see 2 things. With same FIR coeffs (calculated for 48K) i get the same frecuency response in the output (measured with spectral lab) with #define @48KHz or @96KHz or @192KHz, however the cut frecuency should change. And also i get the same latency (however i should get half latency @ 96KHz keeping the same number of coefs.
Having this into account i guess that i am not changing the sample rate just changing the #defines. I am doing something wrong, ot there are just more parameter to be changed???
I am using a example bypass with a fir filter, sample processing. (Fir works perfectly at 48Khz, i get the same at 96KHz), 21489 board with 1939 codec and crosscore.
I appreciate if someone could help me because i want to process audio just at 96KHz!.
