I’m quite new to using JUCE and have been trying to create a delay effect that has an IIR filter on the delayed buffer. Currently I have a working delay which I made following this tutorial (Juce Tutorial 40- Building a Delay Plugin Pt 1 (Creating a Circular Buffer) - YouTube) and can successfully filter the full signal. However, when I try and filter the delayed buffer I blow up the meters to red and just get white noise. I am not sure what I have to do here and am hoping somewhere here might have an idea.
In the code I try and pass the delayBuffer into the IIR filter and get the results stated above. If I pass in the buffer that is passed into the ProcessBlock function then it works fine, but filters the whole signal.
Thanks in advance.
