Question:
On my computer when I download songs form iTunes they show up as m4a files... i was wondering how I made my computer do this. As opposed to on my friends computer which downloads everything as an m4p.
Answer:
.m4p as an file extension is almost identical to .m4a and .m4b extensions, thus being a MPEG-4 file container for encoded audio. The encoding (compression method) of the audio can be virtually anything, but the AAC -based encoding is currently the most common one.
The one big difference between .m4a and .m4p is that M4P is Apple's version of the M4A format that includes DRM protection, called FairPlay. This is the format used for protected music purchased from the iTunes Music Store.
M4B format can be "bookmarked," allowing an MP3 player to return exactly to the last listening point. M4B is popular for audio books and podcasts for this very reason.
