Project

A project is a collection of sound data you want to work on at the same time. When you open the Workspace, you also open a project. STx does not store the sound files itself in the project, but rather stores a reference to them. The metadata (segments, parameters, sequences, etc) can be stored in the project itself to facilitate multiple segmentation of the same wave file.

The contents of the project file are displayed in the overview and detail section of the workspace window.

When you start STx for the first time, the default project default.stxpr will be opened with sample of data using all of STx's project features.

Project Elements

Sound Files

The most basic use of STx is to listen to and analyse sound files. You can drag and drop a sound file into STx and then analyse it, extract and save parameters, and annotate it. STx currently supports the WAVE format.

Sequences

You can generate your own signal using a mixture of sound file segments and dynamically generated signals. This is called a 'sequence' in STx.

Segment Lists

You can combine segments from different sound files into a segment list. This may be useful for, e.g., comparing different speakers within one analysis.

Link

A link to a software program or document on the user's computer. Please read this article for more details.

Sets

Sets are a collection of any of the above elements. Theoretically, you can change it's properties although it is unlikely that you will need to.

Linked or unlinked

You can either store your metadata in your project file (unlinked) or in one file per wave file (linked).

Note: STx metadata was stored in SD0 files prior to version 3.0. See SD0 Import/Export for more details. STx settings and configuration data is stored in the Workspace file, not the project file.

XML Structure

The STx project file uses XML to store it's data. A detailed description of the XML data structure of a project file can be found here.

Backups

STx makes, by default, backups of the project file. These are stored in the backup directory.
