# `TestData for NeuroNexus Allego Recording` The Allego format has one json metadata file, and two headerless binary files with the suffix `.xdat`. One file is a float32 file of all raw data (`*_data.xdat`) and the other is the int64 timestamp file (`*_timestamp.xdat`). This recording is ~ 1 second with digital channels also included.
