lrc to wav conversion can actually mean several things, but it is most notably searched by people that would like to view or add lyrics (saved in .lrc files) as part of their multimedia file.
This is possible, but not with WAV. You can show lyrics during playback in multimedia players that offer this option, but if you want to embed the lyrics to the files, you have to use a container format like MP4.
Often done for karaoke or similar purposes, because standard multimedia players do not show lyrics during playback. Of course you can make a blank video with the lyrics acting like subtitles as well, but for this you will need a video editor and embed the lyrics in subtitle format.
