5 File Formats

This chapter describes the file types used with HARK and their formats. In HARK , a file can be used for module input, module output, or for storing property settings. Table 5.1 gives a list of the file types used in HARK .

Here, Julius  formats basically conform to the file formats of Julius . For differences from the original Julius , see the description of JuliusMFT . File formats other than Julius  are described below. The input-output of HGTF (HARK General Transfer Function), binary format and HARK text format are collectively supported by the input-output library harkio of HARK  and their generic name is HARK file format. Other formats, including srcinf text, PCM binary, float  binary, localization result text, Map  text, and correlation matrix text formats will be modified in future versions of HARK  so that they can be supported by harkio.
