How to store metadata in RIFF/WAV files is not straight forward thing:

Looks like there are two options (which can be combined):

1. Store metadata in the RIFF-LIST-INFO chunk
2. Store metadata in non-standard, but better supported: RIFF/ID3v2.3

There is also some inconsistency in storing the ID3v2.3 chunk, some application use 'id3 ', others use 'ID3 '. This is how some applications handle the RIFF/WAV metadata:

	Mp3Tag v2.8	Windows 10 Explorer	foobar2000 1.3.14	Windows 10 Explorer Media Player
Reads RIFF/LIST-INFO	✖	✖	✖	✖
Writes RIFF/LIST-INFO	✔	does not write	✔	does not write
Writes RIFF/ID3v2	✔	does not write	✔	does not write
Reada RIFF/'id3 '/ID3v2	✔	✔	✔	✔
Reada RIFF/'ID3 '/ID3v2	✔	✔	✔	✔
Writes RIFF/ID3v2 chunk-id	'ID3 '	does not write	'id3 '	does not write

Notice that I did not found a single application which was able read from the RIFF/INFO tag; although it is apparently written in addition to the ID3v2.3 chunk.

Useful stuff:

• Utility to visualize RIFF chunks: RIFF File Viewer
• RIFF Tags, RIFF Info Tags
