I have been tyring to implement a simple chorus effect on the ADAU1701 using a voltage-controlled fractional delay, and a couple of sinusoidal oscillators.
When I download and run the attached SigmaDSP program, the ADAU1701 outputs click and pops even with no signal present. These can actually be seen using the real-time display, as shown in the screen grab.
I don't understand the source of the problem, but I do know that when the oscillators are turned off, the clicks and pops stop.
I would love help from anyone who could explain what I'm doing wrong.
