Note: The first codec I'm going to talk about this WAV. Now, WAV isn't actually an audio codec. WAV is actually just an audio container for raw audio, which I'll talk more about later.

WAV was originally developed by IBM and Microsoft in 1991. It used to be a patented audio format but the patent has since long expired.

Fun Fact: WAV is not just restricted to raw audio. It can represent many analog signals, up to 2.1GHz.

WAV is also extremely easy to parse since it's basically just raw audio.
