Analyze_FFT256IQ

Just a quick question ..

I'm running a teensy 4.0 and rev "d" audio shield .. no issues
I can generate the I/Q requirements and the the FFT Display works fine ... But I can only drive it via the audio Input (i2s) Object .. if I try to attach it to a mixer out, or via an AMP object it fails ..
is there something I am missing ... or is this by design?

Thanks all
cheers

Post your code which tries to "attach it to a mixer out" and explain how it fails.

Disregard my post .. I had a conventional FFT running off a mixer and the second taking I/2 from a different source ... I thought about what you said .. walked away from it and fixed it .. thanks for the push!
