[Question] is it possible to connect an existing Audio Context / Buffer to Pizzicato?

Currently working on a project that expands upon an audio engine.

People are able to either make new sounds with pizzicato or convert their existing files into pizzicato.
The issue is, the existing files exist in Audio Contexts. Im able to extract the buffers, unit8arrays and everything...

I want to know if its possible to do as the title says
