To follow up, there is

Binaries of the plugins are available from

The commandline tool is currently only available when building from source.

Brute force indeed...
Works sufficiently well and fast, I have a few ideas how to integrate it
into the plugins, but it is tricky since it requires context.
Now
don't believe that phase shifting a signal will always result
in a waveform with a lower peak/RMS ratio. It could very well
have the opposite effect.
Well, there is a minimum. So far I just brute force detect it, trying
all angles in 1 deg steps on a file. In other words, this really kills whatever snappy
transient response
you may have had.
I did some listening tests, both on individual samples as well as
using
the plugin on the master-bus with various performances. In many cases it
is audibly transparent.
But yes, it can kill quality, just like [multiband] compressors,
limiters, or any tool, really.
On the upside I now have better understanding of segmented convolution,
hilbert filter and related FFT topics, which is what this exercise was
about.
Cheers!
