From Just Solve the File Format Problem
NPR, in a music file format context, does not refer to National Public Radio, but to the arrangement files created by Steinberg Nuendo.
Nuendo and Cubase are able to load one another's files (NPR and CPR), except when some new features (VCA) are used that differ in the programs.
File Information
NPR Nuendo files are based on the RIFF file format using type "NUND". Identical header to CPR
