Accessing amplitudes The following functions can be used
to access to amplitude of the track at certain points. Most of these functions can be used for reading or writing to this point, thus tr.a(10, 5) = 10.3; can be used to set the 10th frame of the 5th channel and cout << tr.a(10, 5); can be used to print the same information. Most of these functions have a const equivalent for helping the compiler in read only operations.

Auxiliary channels
Auxiliary information is used to store information that goes along with frames, but which are not amplitudes and hence not appropriate for operations such as interpolation, smoothing etc. The aux() array is an array of EST_Vals which allows points to be int, float or a string. The following functions can be used to access to auxiliary track information. Most of these functions can be used for reading or writing to this point, thus tr.aux(10, "voicing") = 1; can be used to set the 10th frame of the "voicing" channel and cout << tr.a(10, "voicing"); can be used to print the same information. Most of these functions have a const equivalent for helping the compiler in read only operations. Auxiliary channels are usually accessed by name rather than numerical index. The names are set using the set_aux_channel_names() function.

EST_Val &	aux (int i, const char *name)

Definition at line 419 of file EST_Track.h.

float & EST_Track::a	(	int	i,
		const char *	name,
		int	offset = `0`
	)

return amplitude of point i, in the channel named name plus

offset. If you have a track with say channels called F0 and voicing, you can access the 45th frame's F0 as t.a(45, "F0"); If there are 20 cepstral coefficients for each frame, the 5th can be accessed as t.a(45, "cepstrum", 5);

Definition at line 403 of file EST_Track.cc.

float & EST_Track::a	(	float	t,
		int	c = `0`,
		EST_InterpType	interp = `it_nearest`
	)

return amplitude of time t, channel c. This can be used for

reading or writing to this point. By default the nearest frame to this time is used. If { interp} is set to { it_linear}, linear interpolation is performed between the two amplitudes of the two frames either side of the time point to give an estimation of what the amplitude would have been at time { t}. If { interp} is set to { it_linear_nz}, interpolation is as above, unless the time requested is off the end of a portion of track in which case the nearest amplitude is returned.

Definition at line 437 of file EST_Track.cc.

float& EST_Track::operator()	(	int	i,
		int	c
	)

void EST_Track::fill_time	(	float	t,
		int	start = `1`
	)

set frame times to regular intervals of time {\tt t}.

The { start} parameter specifies the integer multiple of { t} at which to start. For example, setting this to 0 will start at time 0.0 (The default means the first time value = { t}

void EST_Track::fill_time	(	float	t,
		float	start
	)

set frame times to regular intervals of time {\tt t}.

The { start} parameter specifies the first time value.

Definition at line 794 of file EST_Track.cc.

void EST_Track::fill_time ( const EST_Track & t )

fill time channel with times from another track

Definition at line 802 of file EST_Track.cc.

void EST_Track::fill ( float v )

inline

fill all amplitudes with value { v}

Definition at line 500 of file EST_Track.h.

void EST_Track::sample ( float shift )

resample track at this frame shift, specified in seconds.

This can be used to change a variable frame spaced track into a fixed frame track, or to change the spacing of an existing evenly spaced track.

Definition at line 671 of file EST_Track.cc.

float EST_Track::shift ( ) const

return an estimation of the frame spacing in seconds.

This returns -1 if the track is not a fixed shift track

EST_read_status EST_Track::load	(	const EST_String	name,
		float	ishift = `0.0`,
		float	startt = `0.0`
	)

Load a file called {\tt name} into the track.

The load function attempts to automatically determine which file type is being loaded from the file's header. If no header is found, the function assumes the file is ascii data, with a fixed frame shift, arranged with rows representing frames and columns channels. In this case, the frame shift must be specified as an argument to this function. For those file formats which don't contain provision for specifying an initial time (e.g. HTK, or ascii...), the { startt} parameter may be specified.

EST_read_status EST_Track::load	(	EST_TokenStream &	ts,
		float	ishift = `0.0`,
		float	startt = `0.0`
	)

Load character data from an already opened tokenstream {\tt ts}

into the track. The load function attempts to automatically determine which file type is being loaded from the file's header. If no header is found, the function assumes the file is ascii data, with a fixed frame shift, arranged with rows representing frames and columns channels. In this case, the frame shift must be specified as an argument to this function For those file formats which don't contain provision for specifying an initial time (e.g. HTK, or ascii...), the { startt} parameter may be specified.

EST_read_status EST_Track::load	(	const EST_String	name,
		const EST_String	type,
		float	ishift = `0.0`,
		float	startt = `0.0`
	)

Load a file called {\tt name} of format {\tt type}

into the track. If no header is found, the function assumes the file is ascii data, with a fixed frame shift, arranged with rows representing frames and columns channels. In this case, the frame shift must be specified as an argument to this function For those file formats which don't contain provision for specifying an initial time (e.g. HTK, or ascii...), the { startt} parameter may be specified.

EST_write_status EST_Track::save	(	const EST_String	name,
		const EST_String	EST_filetype = `""`
	)

Save the track to a file { name} of format { type}.

Definition at line 1230 of file EST_Track.cc.

EST_write_status EST_Track::save	(	FILE *	fp,
		const EST_String	EST_filetype = `""`
	)

Save the track to a already opened file pointer{\tt FP}

and write a file of format { type}.

Definition at line 1254 of file EST_Track.cc.

int EST_Track::prev_non_break ( int i ) const

starting at frame i, return the frame index of the first

value frame before i. If frame i is a value, return i

Definition at line 644 of file EST_Track.cc.

int EST_Track::next_non_break ( int i ) const

starting at frame i, return the frame index of the first

value frame after i. If frame i is a value, return i

Definition at line 629 of file EST_Track.cc.

void EST_Track::rm_excess_breaks ( )

If the contour has multiple break values between sections

containing values, reduce the break sections so that each has a single break only.

Definition at line 810 of file EST_Track.cc.

bool EST_Track::single_break ( ) const

inline

return true if track has only single breaks between value sections
