How do you write an edited file to disk ?

Changes are instantly written to disk, there is no need to explicitly save anything.

Of course, you can Undo any changes you may not be satisfied with.

I edited RIFF (.wav, .aiff) audio files with Meta, why are the Tags not showing in iTunes ?

This is because iTunes does not read tags from Metadata stored in RIFF (.wav/.aiff) audio files:
Information is only stored or read using its own media database: the iTunes Library.

I have some audio files opened in program X, why aren't the changes I made using Meta showing ?

There's a fair chance your program only reads metadata once (upon startup, or when scanning files) and doesn't automatically detect live changes to the files you are editing with Meta. Another possibility is that the program uses its own database, and hasn't refreshed the changes yet.


To show the changes, try reopening the program so that it parses the files' Metadata again, or try changing the current folder in your program's file browser, to force a refresh.

I have tagged some mp3 files properly, but the Finder won't show the tags, why ?

Up to Mac OSX 10.11, the Finder could only read ID3v2.3 Tags. Meta, by default writes ID3v2.4, but you can change the desired version in the app's Metadata preferences tab.

What is the difference between Capitalize and Titlecase ?

Capitalize will make the initial letter of every word uppercase and everything else lowercase.


Titlecase behaves in a similar way, only it does not touch words that are already uppercase, and will apply some context: Terms like LP or EP will always be uppercase, and small words (articles, coordinating conjunctions) will be kept lowercase.

Does Meta support pulling track information and cover art from online services such as FreeDB or Discogs ?

Unfortunately, not yet.
