The audio codec is simply software/hardware, to convert audio from an [audio coding format](#audio-coding-format) to playable audio and vice versa.
# ID3
[ID3](https://en.wikipedia.org/wiki/ID3) is a metadata container format for audio. I am going for [ID3v2](https://en.wikipedia.org/wiki/ID3#ID3v2)
An Application can define its own types of frames.
There are standard frames for containing cover art, BPM, copyright and license, lyrics, and arbitrary text and URL data, as well as other things.
Version 2.4 of the specification prescribes that all text fields (the fields that start with a T, except for TXXX) can contain multiple values separated by a null character. The null character varies by [character encoding](https://en.wikipedia.org/wiki/Character_encoding).
