Convolver + ReplayGain

[AnnieBody]

I am currently using minimstreamer with a convolver file:
convOut=-i "C:\Internet\MinimServer\opt\bin\convolution\CD7NT_Impulse.wav" -lavfi afir
works very well!

I now want to use the replaygain tag to auto change volume for playlists:
convOut=-af volume=replaygain=track
works very well!

Despite many attempts, what I can't seem to do is get both working together without generating an error.
Can anyone offer a way to combine both these stream options?

Also, just for a little light reading, where can I find out more info regarding the '-(something)' options? I want to know more about what they are doing, rather than just type them in because I have been advised to!
Regards and thanks

See this post for an example of how to combine replaygain and convolution.

The minus options such as -lavfi and -af are described in the FFmpeg documentation.

I created 3x mp3 and 3 x flac files from one wav track. To these I manually added (using Mp3Tag) the replaygain trackgain of 0db, +12db and -12db so I had one of each gain per file type.

After much trial and error I have found the following settings partially work:
stream.transcode
dsf(>64):wav24;176, wav(>24;192):wav24;192, mp3:wav24, flac:wav24; [only the mp3 and flac settings relate to replaygain]
stream options
convOut=-i "C:\Internet\MinimServer\opt\bin\convolution\ORA10_HD650_Impulse.wav" -lavfi "afir=gtype=gn,volume=replaygain=track"

I say partially because the replaygain +12db doesn't appear to work.
If I play the files on my PC using foobar then the gain differences are clearly and unmistakingly audible.
But when I use MinimServer only the -12dB is applied, the other two tracks having the same volume.
So what is preventing the replaygain + setting from being utilised?

Please refer to the link I posted in post #2 of this thread. The replaygain option needs to appear first.
