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 .

Table 5.1: HARK module list that designates file input-output

Module name	Where to use	File type	File format
SaveRawPCM	Output	PCM raw file	PCM binary
LocalizeMUSIC	Property setting	Source localization transfer function file	HGTF binary
SaveSourceLocation	Output	Source localization result file	Localization result text
LoadSourceLocation	Property	Source location result file	Localization result text
GHDSS	Property setting	Sound source separation transfer function file	HGTF binary
	Property setting	Microphone position file	HARK text
	Property setting	Stationary noise position file	HARK text
	Property setting	Initial separation matrix file	HGTF binary
	Output	Separation matrix file	HGTF binary
SaveFeatures	Output	Feature file	`float` binary
SaveHTKFeatures	Output	Feature file	HTK format
DataLogger	Output	`Map` data file	`Map` text
CMSave	Property setting	Correlation matrix file	correlation matrix text
CMLoad	Output	Correlation matrix file	correlation matrix text
JuliusMFT	Startup argument	Configuration file	jconf text
	In configuration file	Acoustic model / phoneme list	julius format
	In configuration file	Language model / dictionary	julius format
harktool	harktool	Source position list file	srcinf text
	harktool	Inpulse response file	`float` binary

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.
