In a post on his “Zunester” weblog titled “More Than You Ever Wanted to Know About Audio Formats”, David Caulton describes AAC thusly (emphasis added):
AAC — designed for MPEG, by MPEG. Largely associated with Apple at
this point, AAC was designed by a licensing body, complete with
patent pool, etc. Licensable by anyone for a (relatively pricey)
fee from MPEG-LA. High compression efficiency. Compatibility is fine
— as long as you buy Apple products.
Now let’s look at Microsoft’s Zune Media Formats web page:
Zune supports the following audio formats:
- Microsoft Windows Media Audio (.wma)
- MP3 audio (.mp3)
- AAC audio (.m4a, .m4b, .mp4)
Perhaps Caulton should want to know more about audio formats.
