Who controls the CLF format specification?
The CLF format is controlled by a small group software developers and CLF data authors. The full list can be found here.
What resolution does the CLF format use?
CLF v1 supports two data
resolutions. A CLF Type 1 file contains Octave/10 degree data, a CLF Type
2 file contains Third Octave/5 degree data. Two resolutions are used to
support legacy data that is only available in the lower resolution format.
Authors are encouraged to publish data in the 'as measured' format so that
end users know what they are using.
CLF2 v2 supports optional
phase, filters and multipart files (for modeling multi-way loudspeakers
and improved array modeling)
End users can use the free CLF viewer to view the contents of a CLF file. To use the data for a design you need software that can import the binary CLF format data (CF1 and CF2).
Start by downloading the CLF Authoring kit. Once you are familiar with the requirements, request an author key (free) and an upgrade to the fully functional software. Note that for data integrity reasons CLF authoring is primarily meant for manufacturers and independent measurement services that measured the data or arranged to have it measured via an independent measurement service.
