EST_Track differentiate ( EST_Track &  c,
float  samp_int = 0.0 
)

Calculate the simple derivative of a track. This is given by

\[a_{i+1} - a_{i}\]

The values in the resultant track are spaced midway between the values in the input track, resulting in 1 fewer frames in the track. This is a very local estimation of the derivative of the track at a point in time. A smoother value can be obtained using the delta function.

float get_time_frame_size ( EST_Track &  pms,
int  i,
int  prefer_prev = 0 
)

Return the frame size in seconds based on analysis of current time points. This function basically determines the local frame size (shift) by subtracting the current time point from the next time point. If the prefer_prev flag is set to true, or the index is the last in the track, the size is determined by subtracting the previous time point from the current one.

This is most commonly used in pitch synchronous analysis to determine the local pitch period.

int get_frame_size ( EST_Track &  pms,
int  current_pos,
int  sample_rate,
int  prefer_prev = 0 
)

Return the frame size in samples based on analysis of current time points. This function basically determines the local frame size (shift) by subtracting the current time point from the next time point. If the prefer_prev flag is set to true, or the index is the last in the track, the size is determined by subtracting the previous time point from the current one.

This is most commonly used in pitch synchronous analysis to determine the local pitch period.
