Technical Details The Ogg format was created as a framework which are available free of charge and re-implementable in software. The format consists of chunks of data referred to as Ogg Pages. A BSD licensed library called LibVorbis is used to encode and decode the data from the Vorbis streams. Currently there is no official standard for including metadata in Ogg containers, but must be included in the Codec.

Description The M4R is an iPhone ringtone file that is essentially a renamed AAC (m4a) file. Not all iTunes Music Store songs can be used to create M4R ringtones. In order to create an M4R ring tone from an iTunes song, the song must allow for M4R ringtone creation. An M4R ring tone is automatically transferred to a user's iPhone when the iPhone is synced with the user's computer.

Technical Details M4R is essentially a renamed AAC (M4A) file - it is similar to MP3 but compresses the digital audio files further. It is part of the MPEG-4 standard and is specified in the ISO/IEC standard 14496-3. It is a lossy algorithm much like AAC and MP3. M4R supports auditory masking - essentially discarding data with minimal loss of quality.
