VERIFY — Plots of vox time series, verify segmentation marks

Plots time series from raw data tapes as well as from "compressed" high density tapes. A plot is generated to fit either A4 or A3 paper format (cf. program PLOTTER). Each plot page displays a time series of 20 seconds length at a resolution of 2048 Hz. These plots are mainly used for test and documentation purposes, but they may also serve as basis for a "manual" segmentation of time series with respect to pauses and utterances.

            - NREC = 0: All files
                   = n: First "n" files are to be processed
 
            - NBIT = n: Number of bits used in A/D-conversion (default=16)
 
            - IBM  = 0: Input data are stored in X86/X64-mode   (little endian)

            - PROT = 0: No protocol

                   = 2: Detailed protocol
 
            - PLOT < 0: Segmentation marks are written to unit "LPRT"
                   = 0: No plots
                   = 1: Time series
                   = 2: Time series with pre-existing segmentation marks

            - PEND = p: Specifies last page to be plotted
 
            - AMPL = r: Time series are amplified by factor "r" prior to
                        plotting
 
            - NGL  = 0: Filter parameter is automatically selected
                   = q: Filter parameter is explicitly specified
 
            - SCUT = 0: Filter parameter is automatically selected
                   = q: Filter parameter is explicitly specified
 
            - LG30 = u: Logical unit number associated with input tape
 
            - LPRT:     Logical unit number of plot-device (standard=6;
                        valid numbers are 46-96)
 
            - PROB = 0: All probands
                   = n: Only proband "n" is to be processed
 
 
            - DEMO: Plot of speech recordings of 20 second length

Fig. 19: Comparison of mean vocal pitch in healthy male speakers (upper half) versus healthy female speakers (lower half) computed for the experimental condition of "reading out loud emotionally neutral text". It is worth noting that (1) the differences in mean vocal pitch between males (110 Hz) and females (220 Hz) are, on average, exactly 1 octave; and (2) the international concert pitch in music (440 Hz) is related to this average mean vocal pitch (2 octaves from male, and 1 octave from female vocal pitch).
