An introduction to computer audio
WAV can be perfectly tagged but due to a lack of standards portability of the tags is an issue.
JRMC supports tagging WAV and AIFF.
WAV & AIFF tagging uses the ID3v2 tag format for storing their tag data. This is the same format popularized by MP3.
These tags are stored in a chunk at the end of the file. WAV & AIFF files are made up of chunks, and adding chunks is fully standards compliant.
The tag makes no changes in the audio data stored in the file, and of course, doesn't change the bit perfect output nature of the audio output.
Writng ID3 tags in WAV is a non-standard solution supported by a couple of programs.
In Jriver 18 you can mange the WAV plugin in Options > Audio > Advanced.
Tagging WAV/AIF is on by default.
In older versions of JRiver tagging WAV is off by default an can be enabled using the plugin manager in the DSP studio.
