Room correction with convolution per sample rate

[simoncn]

In FFmpeg 4.1, the afir filter has some settings for applying different gain computations (see this section). The default is gtype=peak. If you specify gtype=gn instead, you should get something close to JRiver. The syntax for specifying this is:

convOut=-i /mnt/disk1/share/MinimServer/convolution/Cor1S44.wav -lavfi afir=gtype=gn

Another possibility is to use gtype=none. This seems (for me) to produce results similar to gtype=gn.
