I'm experiencing some troubles creating a stereophaser effect for demonstration purposes at our university.
I'm still new into that DSP stuff, so I took a former thread as a basis for my project (Custom IIR block on Sigma Studio)
There were really helpful posts to get me more into this.
So I started a new project and I already have played around with the coefficients and the frequency of the oscillator to make it already sound like a phaser.
But currently I'm trying to make the phaser controllable by using the 4 AUX ADCs.
I use the Elektor ADAU1701 Board, so there are 4 pots soldered to the auxiliary ADC.
I'd like to use those pots to control parameters such as Mix, Depth, Rate and Feedback.
Currently just the mix-input is working. I can't really take notice of the inputs for rate and feedback I have done.
How is depth control different than mix? Does it just mean the amplitude of the VCO?
I have attached a screenshot of the main schematic and the SigmaDSP project below.
Hopefully someone could help me. Thank you!
