IMPORT — Convert files from microsoft wave-format to vox-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 imports Microsoft *.wav files that have been recorded through laptops. When imported, 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.

            - MODE = 0: Files are imported from MS wave-file format
                   = 1: Old vox-files are converted and stored in single file
 
            - LIDS = C: Logical unit number of ident file containing
                        proband details of the files to be converted (MODE=0)

Fig. 16: The speech recordings of our normative studies are carried out in an acoustically shielded laboratory, thus guaranteeing a reproducible setting and the acoustic conditions required for a dynamic range of 60 decibel (dB). Speech signals 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. The above Figure gives a visual impression of the complexity of speech signals.
