SOX_OPTS is implemented by sox(1) itself, not dtas.

Furthermore, SOX_OPTS is intended for "--" options (e.g.
"--no-clobber"), not effects chains such as "sinc".

I think you added $SOX_OPTS to "command:" yourself, since I
can't find evidence in dtas.git history that ever put $SOX_OPTS
in the command-line.

You can put arbitrary variables there, such as MYFX, of course:

command: exec sox "$INFILE" $SOXFMT - $TRIMFX $RGFX $MYFX
env: !!omap
- MYFX: sinc -850


Btw, I started looking into your auto-pause thing the other day
but got sidetracked by Ruby 2.7.0dev problems :<  I wish I had
written this in Perl5 or even C99...
