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.
What is AMR?
Adaptive Multi-Rate (AMR) is an audio data compression scheme optimized for speech
coding. AMR was adopted as the standard speech codec by 3GPP in October 1998 and
is now widely used in GSM and UMTS. It uses link adaptation to select from one
of eight different bit rates based on link conditions.AMR is also a file format
for storing spoken audio using the AMR codec. Many modern mobile telephone handsets
will allow you to store short recordings in the AMR format.
