Problem with externally controlled peaking filter
Thread Summary
The user encountered a popping sound and silence when using a peaking control with the ADAU1701 and Dayton Audio KABD250 in SigmaStudio 4.51 Beta. The issue was resolved by correctly setting the DC Constant Block to 28.0 instead of 5.23. The engineer suggested checking Dave's YouTube channel for additional SigmaDSP and SigmaStudio tutorials.AI Generated Content
Hi, Have most of the info for my DSP project with the ADAU1701 and the Dayton audio KABD250. I'm using SigmaStudio 4.51 Beta. I'm having a problem putting in a peaking control. I copied the circuit exactly from Dayton's sample projects. I'm using the Filters > Second Order > Lookup > Double Precision > 2 Ch > General 2nd Order w var Param/Lookup/Slew along with a DC Constant block and an ADC 3 for the mechanical control. I first tried to set the curves to 19 like the Dayton Example, but it would only go to 15.999999. So I tried it with 12 curves. Whenever I turn the knob up half way, I get a pop in the speakers and silence. The only way it won't pop is if I set the maximum curves to 3. I did a very simple schematic to test and the problem persists. I'll see if I can attach screenshots. Is there an incompatibility with this block? Is there a way around this using a different block and combinations? Thanks so much for your help!

Please disregard this. I discovered that the DC Constant Block was incorrectly set to 5.23, when it should have been set to 28.0. Now it works fine. I'll use the excuse that I'm just a beginner.
Hello,
Sorry for not being able to respond earlier.
We are glad that you have resolved it yourself, Happy learning!
Please have a look at Dave's YouTube channel, it will be very handy when you start with SignamDSP and Sigma studio. I have attached the link below.

Sorry for the delayed reply. I'll check it out. By the way, I'd gladly pay for a downloadable manual for the toolbox.:)
Hello,
If you want the details about any blocks in tree toolbox then highlight the block and press F1, it takes you to the wiki page where every detail about the block is given.
For example,
I highlighted (green border around the block) a compressor block and pressed F1, it took me to this below wiki page.

Thanks Harish. That's definitely helpful. I was thinking that it would be nice to have a manual you can take with you to read up on SigmaStudio when you aren't at your computer.
