That's a large command for us to have to parse. I recommend omitting 
anything that isn't required to reproduce the issue and to provide a minimal
command that still shows the problem. It will increase your chances to receive
answers. Provide a link to any files that are needed so we can try it if it can't
be reproduced with synthetic inputs (testsrc2 and sine filters for example).
