I have an ADAU1452MINIZ development board that i am using for two active three way speakers. I am inputing signal to the board via optical spdif.
The problem that i am experiencing is that if i program a filter at, for example, 200Hz, the dsp will process at 100Hz. So for every frequency i use i have to input double than what i want. I have checked this with my calibrated measurement microphone.
Maybe the solution to my problem is simple, but i am very new to programming and i don't now exactly what setting to correct in the register controls of the ADAU1452.
Thank you for your support.
