Tools I use for audio/video downloading, media conversion and audio editing

Posted by jpluimers on 2020/07/03

A friend asked me what tools I use for downloading media, converting it to various formats (including audio extraction) and audio editing.

It is a surprisingly short list:

Most of it runs out of the box on Mac OS X/MacOS/OS X, as I’ve moved there form Windows for most of my day to day access to systems (there is a great set of Microsoft Remote Desktop in the app store: [Archive.isMicrosoft Remote Desktop 8.0 on the Mac App Store and [Archive.isMicrosoft Remote Desktop 10 on the Mac App Store; I like the first one better).

Audacity shortcuts

Shortcuts make Audacity life a lot easier. For keyboard shortcuts, Mac users use Command (⌘) instead of Ctrl.

Audacity error when starting “The application “Audacity.app” can’t be opened.”

Posted by jpluimers on 2020/06/29

For quite a while, I had the error “The application “Audacity.app” can’t be opened.” and Audacity still opening. Clicking the OK button often enough made me hunt for the solution:

This is what I did:

$ cd ~/Library/Application\ Support/audacity
$ grep Temp audacity.cfg
TempDir=/Users/jeroenp/Library/Application Support/audacity/SessionData

Then I checked if the directory existed:

$ find ~/Library/Application\ Support/audacity -type d
/Users/jeroenp/Library/Application Support/audacity
/Users/jeroenp/Library/Application Support/audacity/AutoSave
/Users/jeroenp/Library/Application Support/audacity/Plug-Ins
/Users/jeroenp/Library/Application Support/audacity/SessionData

The odd thing is the directory already existed, so I decided to delete the line, but first needed sed -n (the -n is important: it list only non-matching lines to stdout, see [WayBack] regex – What actually the meaning of “-n” in sed? – Stack Overflow):

$ sed -n '/^TempDir=/p' ~/Library/Application\ Support/audacity/audacity.cfg
TempDir=/Users/jeroenp/Library/Application Support/audacity/SessionData

Since this is Mac OS/Mac OS X/OS X, the -i parameter requires a string even if it is an empty [WayBack] shell – Delete lines in a text file that contain a specific string – Stack Overflow so we get:

$ sed -i '' -n '/^TempDir=/d' ~/Library/Application\ Support/audacity/audacity.cfg

After that, starting audacity still gave the same error and the TempDir entry was re-added.

So I did this:

  1. renamed the audacity directory to audacity.bad,
  2. recreated an empty audacity directory
  3. created empty subdirectories AutoSave, Plug-Ins, SessionData
  4. looped this loop
    1. Start Audacity
    2. On success copy a missing file in the audacity directory tree from the audacity.bad directory tree

In the end, these files were the cause:

  • pluginregistry.cfg
  • pluginsettings.cfg

Since I wasn’t using any plugins, I removed them. Now audacity starts fine.

Now that I had the files pinpointed, I could refine the search and this seems to be a common problem [WayBack] FAQ:Installation, Startup and Plug-ins – Audacity Development Manual: How can I solve Audacity not appearing or crashing on launch, or crashing after I add a plug-in?.

Too bad that page didn’t show up in the original search results.

So this chapter is very much wort reading: [WayBack] 1. Inside the Terminal – Mac OS X For Unix Geeks, 4th Edition [Book]
