No, Chains can't do that. When applied to the current project, all commands in the Chain are applied to each full track in the project.

I have no idea how Linux handles this, but I'm guessing there's something similar you can do. On Linux it's pretty straightforward for a standard install: 1) Open the "home" folder (opens "/home/user-name" in the default file browser) 2) "Ctrl+H" to show hidden folders...

3600 seconds is 1 hour, which is what you said you wanted.
How long do you want the sections to be?

"Regular Interval Labels" (http://manual.audacityteam.org/man/regu ... abels.html) to add labels and regular intervals,
then "Export Multiple" (http://manual.audacityteam.org/man/export_multiple.html)

When you have recorded, you should then "Export" the audio as a 16-bit WAV file, and the "Project Rate" in the lower left corner of the main Audacity window should be set at 44100. That gives you a standard 16-bit 44.1 kHz WAV, which is the correct format for an audio CD. Check t...

It may be better to approach the task as:

Track 1: Aaaa
Track 2: ...Bbbb
Track 3: .......Cccc

When the project is exported, the tracks are mixed down into one file, so that would produce: AaaaBbbbCccc

Noise reduction works best when the noise profile comes from the specific track that you are cleaning, so no it's not a good effect to use in a script.

You have inadvertently enabled "Sync-Lock". Click the clock button to turn it off (see: http://manual.audacityteam.org/man/sync ... roups.html)

You should use the current version of Audacity (2.1.3) from the Audacity website: http://www.audacityteam.org/download/

The vocoder works only on stereo tracks. To apply an effect to one or more specific tracks, select the track(s) that you want to apply the effect to. See here for more information about the Vocoder: http://manual.audacityteam.org/man/vocoder.html See here for more information about selecting tracks:...

A Chain can be applied to the current project, and will then be applied to all tracks in that project.
