There is no id3/tag data. They do not have a "title" nor do they have anything else. That's a problem if your music library predates iTunes and iDevices.
> WAV files can be tagged with metadata in the INFO chunk. In addition, WAV files can embed any kind of metadata, including but not limited to Extensible Metadata Platform (XMP) data[25] or ID3 tags[26] in extra chunks.
That aside: why are you using WAV when there are mature, open lossless compression formats like FLAC?
FLAC is supported in iOS since v11, in Android since Honeycomb, and I'm able to listen to FLAC on a Mac running the now-ancient High Sierra release via the finder's quicklook, or iTunes. I don't think I installed a plugin, but I could be wrong.
This. Funny how "WAVs don't have metadata" has become such a meme. What is really meant is "software doesn't support WAV metadata". This has changed over the past five years or so, though.
