If I have the following setup:
-a:1 -f:s24_be,1,96000 -i:W.raw -eac 400 \
-a:2 -f:s24_be,1,96000 -i:X.raw -erc:1,2 -eac 0,1 -eac 400 \
-a:3 -f:s24_be,1,96000 -i:Y.raw -erc:1,3 -eac 0,1 -eac 400 \
-a:4 -f:s24_be,1,96000 -i:Z.raw -erc:1,4 -eac 0,1 -eac 400 \
Where "singlePara" is a one-channel LADSPA plugin. Does ecasound make
one instance and apply it only the first channel or are four instances
made and applied to each channel. The latter is the behavior of Jack-Rack.
What happens when the LADSPA plugin is 4x4 (four inputs and four
outputs, e.g., bf2quad).
The reason I'm asking is that I have a jack-rack configuration,
comprising a number of 4x4 and 1x1 LADSPA plugins that I'm trying to
duplicate in ecasound, and am having trouble getting the same result in
ecasound as I get with jack-rack. (see
for a screen grab of the set up.)
I want to do it purely in ecasound for file-to-file processing so that
it can run faster than realtime.
Thanks for any help...
