Detailed Description
Speech file preselector.
The speech file preselector serves for simple speech file preprocessing and distribution to directories according to certain criteria. Speech file preselector scans continuously input directories set by SetInputDirectory() and SetPriorityInputDirectory() functions for audio files. Audio files are then processed by channel splitter and each channel is stored in a separate file to output directory specified by SetSpeechOutputDirectory. There is also possibility to filter each channel by waveform filter. This can be enabled by SetUseWaveformFilter(). Based on the statistics collected during filtering the output (filtered) file is stored to one of the output directory according to prevailing character of signal. There is an output directory for speech, silence and technical signals. These directories are set using functions SetSpeechOutputDirectory(), SetSilenceOutputDirectory() and SetTechnicalOutputDirectory().
