The idea is in principal to what you can find in the Additive Synthesis mode of Logic’s Alchemy.
Basically a user would be able to throw a sample at Pigments and have it analyse the harmonic content and reconstruct the sound with partials based on that analysis. This can then used as a starting point where the other features of the Harmonic engine could be employed to further manipulate the sound.
Building on this idea would be to analyse multiple files and offer tools to create a unique blend of these sounds which could then be used as a basis for the Harmonic Engine
