DTMF Tones was originally a plug-in (many years ago), and is now a built-in effect (See: https://manual.audacityteam.org/man/dtmf_tones.html)
Are you referring to the plug-in version, or the built-in version?
There have been a few different versions of “Vocal Remover” over the years. Do you have more than one version installed?
Further to the problems I described above, I thought I’d try uninstalling 2CVocalRemover but I couldn’t find it! I’m pretty sure I uninstalled it a while ago. Not sure why Audacity would be trying to load it?
To try and fix the problem I tried re-installing 2CVocalRemover and it seems to have fixed the problem, however I’m now having problems with a few other plug-ins, in particular, those from Airwindows and TAL. This time, after acknowledging all the errors, Audacity quits.
I’m a long-time Audacity and I usually keep the previous version installed just in case there’s problems with the latest version. At the moment I have 2.2.2 installed and it’s working fine.
It sounds like Audacity is being confused by references to old plug-ins in its settings files. Try resetting the Audacity preferences.
To do that, find the folder:
~/Library/Application Support/audacity/
(where “~/” means your home folder)
When you get the correct folder you will see several files and folders including:
audacity.cfg
pluginregistry.cfg
pluginsettings.cfg
Ensure that Audacity is completely closed (not running in the background), and delete those three files.
When you restart Audacity, it will be reset to its factory defaults.
That’s not a standard configuration file for Audacity, though it could perhaps be from a really old version of Audacity
Please attach the file to your reply so I can take a look (see here for how to attach a file to a forum post: https://forum.audacityteam.org/t/how-to-attach-files-to-forum-posts/24026/1)
