The plug-in installed like a whisper. No flashy tutorials, no animated mascots — just a minimal interface with a glassy plate and a few dials. Kai nudged the decay, watched the waveform breathe, and felt a curious clarity in the room as if the walls had learned to listen. He sent Ellie's track through Purity’s pre-delay, rolled back the high damp, and then, on a whim, engaged the “Air” switch. The vocal popped free from the mix like a boat slipping its mooring.
