I had an issue where I was attempting to apply macros to audio in a project, and certain macros gave me a popup saying “Your batch command of blah blah was not recognized”. I am wondering if this is fixable or has to do with the Audacity version i’m using? I am running Audacity 2.4.2. Please let me know if anything.
SC4 is mo longer distributed with Audacity. You will have had it in a much earlier version of Audacity - it may even continue into later updates, but will disappear of you reset your Audacity configuration.
There is no separate Hard Limiter ans Soft Limiter any more - they were replaced a while back with a single Limiter effect where you can set hard or soft options.
PopMute is not an effect distributed as part of Audacity. It is an optional plugin that you will have added at some time. You may need o re-install this.
Macros can only work with effects that are actually in and enabled in your Audacity installation. If you can’t see an effect in the effects list anywhere than a Macro with such an effect will fail.
