Best Way to Rearrange Audio Clips?

[jademan]

If you or others could explain how to produce the final track in my simple example (having only 2 clips) then maybe I could apply it to a case having ~hundred clips.

If I understand your project correctly, perhaps you can use audacity’s macro feature to help. I tried the following with Audacity on Windows:

SelectAll:
Copy:
Import2:Filename="c:\\users\\jademan\\Desktop\\SilenceA.wav"
SelectTracks:Mode="Set" Track="2"
Paste:
SelTrackStartToEnd:
ChangeTempo:Percentage="-66.667" SBSMS="0"
Import2:Filename="c:\\users\\jademan\\Desktop\\SilenceB.wav"
SelectTracks:Mode="Set" Track="4"
Paste:
Import2:Filename="c:\\users\\jademan\\Desktop\\SilenceB.wav"
SelectTracks:Mode="Set" Track="6"
Paste:
SelectAll:
Align_EndToEnd:
ExportWav:

I think it may do something similar to what you are looking for. You may wish to review the following links:

import / export user-defined macros

OS: Windows 10 Pro x64 build 17134 Audacity version: 2.3.0 Is there any way to export the macros I’ve created so I can import them onto another computer? I’ve searched the install directory but cannot figure out where user defined macros are stored. I’ve also searched audacity help, this forum, audacity faq, general google search. No luck finding any information regarding loading/saving/importing/exporting user-defined macros.

Missing features

Create your two SilenceX files, install the above code as a macro, load in your first clip, and apply the macroo the Project. If you are happy with what you see, Apply macro to selected files. Results to to macro-output subdirectory. Then all you have to do is merge all the files in the new sub-directory.

I hope this helps.
