Convolution Filtering

equalizer=f=27:width_type=q:width=8:g=-2
equalizer=f=37:width_type=q:width=8:g=2.04,adeclip=w=55:o=75:a=8:t=10:n=1000

connected into a filtergraph:

convOut=-filter_complex "equalizer=f=27:width_type=q:width=8:g=-2[1];[1]equalizer=f=37:width_type=q:width=8:g=2.04,adeclip=w=55:o=75:a=8:t=10:n=1000"

I have removed the m=a option from adeclip as this is not accepted by my version of FFmpeg (4.3).

However, I don't see how this would be different from my suggestion of using a single filterchain. In both cases, the audio would pass through all three filters.
