wt file

A .wt file is Surge XT's native wavetable format: a short tagged header followed by the table's frames as raw samples, optionally trailed by metadata.

The header starts with a 'vawt' tag and records the frame size, frame count, and format flags. Frames are stored as raw 32-bit floats or 16-bit integers at power-of-two lengths from 2 to 4096 samples. Surge XT can use a trailer for additional wavetable metadata, including scripts used to generate a table.
