seems to be the newly installed 4.x FFMPEG version.

NOW, it saves without an error, BUT it still doesn't convolute the file Sad

This is how stream.options currently looks like:
convOut=-i /share/CACHEDEV1_DATA/Music/ConvolutionFiles/Echo44.wav

You can definitively confirm the version of ffmpeg being invoked by use of the following command.


Your convout command should also be suffixed with the following to invoke convolution.

You might find this Ffmpeg documentation page useful as well.

Having said all of that, convolution can have a subtle effect on the audio file and you have not hinted at the type of convolution that you are applying. Perhaps, to remove any doubt, you could generate a convolution filter with an obvious effect, e.g. extreme high pass or low pass.
