Sigmastudio fixed processing?
Hello everybody,
I would like to replace analog bass, treble...etc. control by little SigmaDSP, but I need to change these parameters (bass, treble, bass boost, loudness volume) by user (analog potentiometers probably) and if I get it right, sigmaStudio don't allow to control these externally? I know there is some control for volume, but when i want to control bass, treble...I need another MCU to acces DSP RAM and change biquad coefficients calculated by the MCU? Or am I missing something?
Thank you very much!

Hi, this is do able, see the link below.
General (2nd-Order w/ Param / Lookup / Slew) [Analog Devices Wiki]
Also look at some example projects found here, Tutorials [Analog Devices Wiki]. Choose different EQ Presets / Filter with GPIOs I think is the relevant project.
Thank you
