What is M4A?
M4A stands for MPEG 4 Audio. Since MPEG-4 Part 14 is a container format, MPEG-4
files may contain any number of audio, video, and even subtitle streams, making
it impossible to determine the type of streams in an MPEG-4 file based on its
filename extension alone. In response, Apple Inc. started using and popularizing
the .m4a file extension. Software capable of audio/video playback should recognize
files with either .m4a or .mp4 file extensions, as would be expected, as there
are no file format differences between the two. Most software capable of creating
MPEG-4 audio will allow the user to choose the filename extension of the created
MPEG-4 files.
Because of its exceptional performance and quality, Advanced Audio Coding (AAC)
is at the core of the MPEG-4, 3GPP and 3GPP2 specifications and is the audio codec
of choice for Internet, wireless and digital broadcast arenas. AAC provides audio
encoding that compresses much more efficiently than older formats, such as MP3,
yet delivers quality rivaling that of uncompressed CD audio.
What is M4B?
Audiobook file based on the MPEG-4 container format; typically compressed with
.AAC encoding; nearly identical to a .M4A file, but denoted as an audiobook and
can be "bookmarked" by supporting audio players such as iTunes and iPod.
The M4B extension is used by audiobooks downloaded from the Apple iTunes store;
these audiobooks may be copy-protected using Apple's FairPlay DRM, which means
they can only be played on authorized computers or iPods.
What is MP3?
MPEG-1 Audio Layer 3, more commonly referred to as MP3, is a digital audio encoding
format using a form of lossy data compression. It is a common audio format for
consumer audio storage, as well as a de facto standard encoding for the transfer
and playback of music on digital audio players. MP3's use of a lossy compression
algorithm is designed to greatly reduce the amount of data required to represent
the audio recording and still sound like a faithful reproduction of the original
uncompressed audio for most listeners, but is not considered high fidelity audio
by audiophiles. An MP3 file that is created using the mid-range bit rate setting
of 128 kbit/s will result in a file that is typically about 1/10th the size of
the CD file created from the original audio source. An MP3 file can also be constructed
at higher or lower bit rates, with higher or lower resulting quality. The compression
works by reducing accuracy of certain parts of sound that are deemed beyond the
auditory resolution ability of most people. This method is commonly referred to
as perceptual coding. It internally provides a representation of sound within
a short term time/frequency analysis window, by using psychoacoustic models to
discard or reduce precision of components less audible to human hearing, and recording
the remaining information in an efficient manner. This is relatively similar to
the principles used by JPEG, an image compression format.
