vitaltable file
A .vitaltable file is Vital's native wavetable format. It is a readable JSON document describing how the table was built instead of storing only rendered audio.
It stores the wavetable's sources, modifiers, and keyframes. Opening it in Vital restores an editable table instead of a finished stack of frames. Vital can also export packed WAVs with 2,048-sample frames for other synths. Inspect the exported WAV when the destination requires metadata.
