Thank you for the information about the Scripting SDK. I am still looking for help with a script to put a few seconds of silence between regions of a file.

Mm.

By "I have never written a script before,..." do you mean that you have no experience in scripting at all?
You should have basic knowledge of c#, jscript or similar.

For iterating through regions you could use the delivered script "Extract Regions As Files.cs" as a template. It's a c#-script.

Scripting can be very powerful in SF but it is a kind of programming and should only be used for often recurring tasks.

I am a coder and know a lot about programming in a variety of languages, but not about scripting in Sound Forge. Is there an object library or any documentation on what commands are available and how to invoke them? What libraries do I need? The functions I want to perform are all available on the Sound Forge menus and are repetitive tasks.

Great. In the help file there is a point called 'scripting' and below this 'batch scripting'. In the last one is documented a complete objects' and interfaces' catalogue.

You invoke scripts via tools->scripting->Run Script but you can call them by customized key commands too. And as you're using C# (or wscript's basic, but that's not my cup of tea ;-) ) you can use windows' objects too by using lines like:

using System;
using System.IO;
using System.Windows.Forms;
 

As I understand actually it uses the windows scripting engine and you add the sound forge objects and interfaces via:

using SoundForge;

You create scripts by calling the script editor as mentioned above. In the script editor you can open existing scripts, create new ones, compile them and run them.
As suggested you should open the existing scripts and look how they work. One important note: The difference between markers and regions is that regions are markers with a length > 0 but are markers too in an object's view.

For the the task you memtioned the somehow nearest example is "Extract Regions As Files.cs". It should be in the "script menu" folder inside your sound forge's application folder.

Thanks for that info! I will check it out. Probably will return with questions, too.

[1] Where is the Sound Forge object model documented? The documentation in the User Manual seems very high level.

[2] When the documentation in the User Manual says you can write scripts in VBScript. Is this referring to standalone .vbs files that execute within WScript? Does MAGIX provide any VBScript examples?
