xrecode is a Microsoft Windows application for grabbing audio data and converting audio between formats. The .xr21 file is one of the data files used by the application.
The file stores data required by xrecode and is normally managed by the application.
The .xr21 file is used by xrecode on Microsoft Windows. Because it is an internal data file, it may not provide useful content when opened directly and should normally be left for xrecode to manage.
The .xr21 file is not an audio format and is not intended for direct audio conversion. To create a converted audio file, open the source audio in xrecode and use the application's audio conversion function instead.
