Windows Media Audio File
A format of audio stream coding deployed by Microsoft in 1999, it has been serving as a foundation for Windows Media. Its purpose is to store and distribute audio content. Firstly, it was considered as a real alternative for MP3, but then, when ACC appeared, WMA lost partially its significance. It differs fundamentally from MP3 by one realization, and can be installed on an equal basis with other system codecs of Windows 9x.
WMA is characterized by a good compression quality, and therefore it has been adapted later for many audio players, mobile devices, and Playstations. However, due to excessive closure, files in this format cannot be played back on other platforms with satisfactory quality. The new version allows for multi-channel coding of large audio files and coding of voice data. In addition to that, the delay in coding has been significantly diminished thanks to the technology of reduced time dilation.
The name of WMA is being used simultaneously for the file format and the codec. There are some types of the format:
According to Microsoft programmers, an audio file of 64 Kbit/s bitrate has a similar sound clarity as the tracks from the original CD. However, some of advanced users do not share such views. Most often, WMA files are generated in Advanced Systems Format which contains both audio and video content. One of the failures is the impossibility to support bitrate of more than 160Kbit/s.

Adaptive Multi-Rate Codec File
|Description||AMR is a compressed file format that functions to enhance speech coding and it consists multiple sampling rates narrow band devices used in encoding or decoding. Recording of AMR files can be done using mobile phones. For video and audio files to play at the same time or accomplish random access memory, one can utilize the 3GPP format. 160 20- millisecond samples embedded in each frame are coded using AMR using ACELP, DTX, VAD and CNG. Recorded AMR files can be converted into other files allowing their use and for them to be distributed.|
|Technical details||AMR has the ability of encoding signals of ranging from 4.75 to 12.2 kbit/s with quality that begins at 7.4 kbit/s.3GPP took up file format in 1999. It is a method that is utilized by GSM and UMTS, it is uses link adaptation to select one of the eight different bit rates. Link adaptation is optimized by AMR with the best codec devices that exist for it to be used by radio channels and capacity requirements. This only works if the connection is good enough to prevent the loss of audio quality.|
