Convolution and Upsampling

[mm2]

Hi all,

I use upsamling by soxr with great results.
syntax:
convOut=-af aresample=resampler=soxr:precision=32

Now I want to use convolution,
syntax:
convOut=-i /share/ConvolutionFiles/Cor1S*.wav -lavfi afir=gtype=gn

What is the correct syntax for „convOut“ if I want to use convolution and upsampling ?
All my previous attempts have unfortunately resulted in an error

thanks
Max
