Organise your sound files

STx can play, analyse, annotate and modify wave files. The main application - the Workspace - is where you load your sound files and start your analysis from. Your sound files are organised in a project file. You can use the FindFile application to search for wave files on disk and import them into STx.

Analyse a Signal

There are a number of applications for analysing signals in STx.

• Real-Time Analyser - analyse the current sound input as a spectrum, wave or spectrogram graph
• Waveform and Segmentation Viewer - useful for segmenting signals
• Spectrogram and Parameter Viewer - calculate, edit and extract parameters from the signal. Segmentation is also easy here.
• Spectrum Viewer - average the spectra of a signal segment.
• SPExL - an application specifically designed for segmentation.

Record a Signal

The Recorder can be used to save an input stream to disk and segment on the fly.

Command-Line Parameters

There is a minimal set of command line parameters which can be passed to STx.

Tutorials

There are a few tutorials available here.

Scripts, Development, and Extending STx

STx comes with a number of pre-installed scripts - applications written in the STx scripting language, and loaded and run from a text file. You can write your own STx scripts, toolboxes and applications. All the functionality that you find in STx is available to you in the script language. The command line console, integrated debugger and the Programmer Guide will help you.

The Log Window

The little window up on the left hand corner of the screen is the STx Log Window. You can start a number of applications from here, change some general STx settings, and view the log messages.

Appendix

C.G. 20110420: Information bitte an geeigneter Stelle unterbringen:

• Problem Deutsch-PC - Stereo-Mixer unter Windows 7 - ist leicht zu lösen, wennnn der Hardwarehersteller ordentliche Treiber ausliefert. Gedankensplitter:

• Für die Medion-PCs lassen sich Treiber ganz einfach von http://www.medion.de/ herniederladen.
• Danach lässt sich normalerweise schon der Stereo-Mixer aktivieren (rechte Maustaste auf Lautsprechersymbol im Windows-Tray, "Recording Devices" wählen, dort wieder mit der rechten Maustaste in der Geräteliste "Show disabled devices" und "Show disconnected devices" wählen und... schon ist der Mixer "Stereo Mix" da. Den dann einschalten bzw. als Default setzen.)
