.W4A File

The w4a file extension is related to some older now probably no longer used audio format that was generated by iTunes.

Seems to be obsolete without support from any developer.

This w4a file type entry was marked as obsolete and no longer supported file format.

This type of file is no longer actively used and is most likely obsolete. This is typically the case for system files in old operating systems, file types from long discontinued software, or previous versions of certain file types (like documents, projects etc.) that were replaced in higher versions of their original programs.

How to open:

Use Apple iTunes to work with *.w4a files.

How to convert:

Possibly can be converted like any other audio data.
