OK
Thanks
I will try

You may all recall some time ago when I complained about implementing residuals, a feature I had never used and was reluctant to spend time on.
Well…
I’ve been testing external dac support with the new idle code and Windows repetitive playback isn’t really a thing but there are workarounds. The results were driving me nuts. Keep in mind that the Windows sound buffer size is about 10ms.
I’m getting these awful spectral charts but the sine wave looks perfect. Here the left channel is loopback and the right channel is an external dac.
So, I finally thought, I wonder what the residual shows since the time domain looks perfect. Here’s the residual plot
Note the every-10ms peak which matches exactly with my 100Hz spectral mess. Proving it’s not really a sine wave even though it looks like one and clearly there’s a sound system repeat issue.
So, just a thank you for forcing me to implement this.
Mark
ps. here’s a blowup showing the sine wave error and residual display
