TCOPY — Copy/merge vox-tapes, convert tapes to new format
For historical reasons, Master.VOX stores speech recordings (time
series) in internal files ("virtual tapes") that are IBM-3490
compatible without the 2 GB space limitation. This program
copies and compresses virtual tapes, that have been recorded in
the speech laboratory or have been imported from Microsoft *.wav
files. When copied, the raw, digitized time series are
pre-processed with respect to artifacts, segmentation and spectral
analysis. The resulting parameters and tables are written on the
output "tape" as part of the identification record which always
precedes a recording. Parameters and tables are then available to
all subsequent analyses.

01 TANA Name of input file (mode=0/1)
02 TBNA Name of output file (mode=0/1)
03 TBVO Volser of output file (mode=0/1)
04 NVOL Number of volumes to be converted
05 NBIT Specifies number of bits used in A/D-conversion
06 IBM Specifies data format (IBM/SPARC vs. X86/X64)
07 PROT Controls print output
08 MODE Specifies copy procedure
09 LDIR Logical unit number of directory list (mode<0)
10 LG31 Logical unit number of input vox-file (mode=0/1)
11 LG40 Logical unit number of output vox-file (mode=0/1)
12 DEMO Examples that illustrate program function
- TANA: Name of input tape ("NO" means that
DSN-name will not be checked)
- TBNA: Name of output tape ("NO" means that
DSN-name will not be checked)
- TBVO: Volser number of output tape
- NVOL = n: Number of volumes to be processed (mode<1)
= 0: All volumes
- NBIT = n: Number of bits used in A/D-conversion (default=16)
- IBM = 0: Input data are stored in X86/X64-mode (little endian)
= 1: Input data are stored in IBM/SPARC-mode (big endian)
- PROT = 0: no protocol is produced
= 1: Detailed list of files being copied
= 2: same as (1) plus file verification
- MODE < 0: Files are converted from old to new vox-format (1-to-1)
= 0: Old vox-files are converted and stored in single file
= 1: Starts new tape and Creates exact copy of input file
= 2: Concatenation: input file is appended to output file
- LDIR = d: Logical unit number of directory file containing
a list of the files to be converted (mode<0)
- LG31 = u: Logical unit number of input file (mode>0: 30-45)
- LG40 = v: Logical unit number of output file (mode=0-2: 30-45)
- DEMO: Plot of speech recordings of 20 second length

Fig. 17: Speech signals as assessed through a microphone
are digitized online with a sampling rate of 96 kHz and at a
24 bit resolution. The recording procedure yields a 2-3 minute
time series for each of the two standard texts. All time series
are inspected visually and marked with an artifact code where
necessary. Fig. 17 gives a visual impression of the complexity
of speech signals.
