A sound segment (audio segment) is a selected and named sequence of contiguous sound samples in a signal stream. Segments are located in sound files. Access to STx generated sound segments is provided by means of the Segment-List-Window, which opens when a sound file is selected from the sound file list of the STXDataSet. Segment lists specify segment addresses (cue in - cue out time pointers) and associated metadata (attributes and annotations). They support the management of named sound segments of continuous stored signals, whether located in the associated sound file or in an other sound file.
Reference data such as segment addresses and annotations are exported by STx into corresponding reference files of type *.xml. So, for example the soundfile mysound1.wav contains the sound data and the reference file mysound1.wav.xml contains all metadata on sound segments of the sound file mysound1.wav.
Note: reference files *.wav.xml are stored by default in the same disk directory the soundfile is located. In case of migration of soundfile(s) to new disk directory location(s) the corresponding *.wav.xml metadata files should always go with the soundfiles.
How to create Sound Segments in a Soundfile?
There are at least three princinpal ways to create sound segment entries and segment annotations conveniently:
1. Direct Method: click on the segment list window of your opened soundfile hit Ins and input segment name, segment signal addresses and annotations (attributes). Add segments or Edit segments (Hotkey CTRL+E) use quite similar dialog windows:
The sound segment mysegment is defined from 0s to 300s of the current soundfile. The segment data including annotations (TR1= xxx; TR2 = yyy;) appear in the STx segment list and are stored in the *.wav.xml reference file.
Segment annotations (attributes) can use standard Unicode including fonts, such as those from the International Phonetic Association (IPA). Individual annotation fields have to be terminated by a semicolon ";" and carriage return (CR).
Note: right mouse button opens a popup window for segment list management.
