Depending on your DAW software and the plug-ins you use, many of these functional blocks are already resident or built-in to specific plug-ins. But, for example while Phase or Polarity flip is standard in Cubase's mixer, in Pro Tools you would have to use (at the minimum) the Trim plug-in every time you wanted to reverse polarity.

With the SigMod framework instantiated on an audio track, you can build whole chains of the eleven processors to accomplish basic processes like making mono (with the Mono module) of a stereo track or use the Mid/side module to separate out those components of a mixed stereo audio for separate processing.

I especially like using the Protect module on the headphone mix feed! Protect mutes audio throughput when a user-settable threshold is exceeded. If there is audio feedback or a mistake made that would send an ear-crushing tone to the phones, Protect mutes it instantly! It is worth it to avoid embarrassing moments in the studio!

Parallel processing is now possible with any plug-in or chain of plug-ins using the Tap module and the Crossover module lets you experiment with dividing audio for individual processing and/or routing by frequency bands.

Each module can easily be inserted, swapped and moved around in any order to create new options to correct, convert or tweak your audio--there are thousands of possible chains! Sound Designers rejoice!

SigMod is available for $49 MSRP and a special price until the end of February 2019 at $29. Right now, updated version 1.1.1 includes VST3 hosting for using any VST3 plug-in in SigMod and in any DAW host.
