Common Instrument Format The CIF format is based on the same principles as the CLF format but is made for the directivities of natural sources such as musical instruments, talkers, singers, and noise sources, or in short anything but loudspeakers that can essentially be seen as a point source. |

The same
principles as for CLF hold: those having measured suitable data
and want to share them can register as CIF authors and create CIF
distribution
files, and prediction
software developers that want to support the CIF format
can register for the binary format description via
bid@catt.se.
