/*ID3 tags for Wave files.
ID3 (Identify a MP3) is metadata container most often used for MP3 audio files. ID3 signature contains information about the title track, album, artist name, etc. about the file to be stored in the file itself. Please see ID3.

Wave files can also store metadata similar ID3.
The code below shows how to add, delete, and read metadata from the Wav files.*/
