DescriptionThe Adaptive Multi-Rate format was specifically designed for speech coding. Many phone providers use the AMR format to store short audio recordings but shouldn't really be used to store other audio such as music due to it's design. In 1999 AMR was adopted as the chosen speech standard for 3GPP. The AMR file is often converted into other formats to allow for use and ease of distribution.

Technical DetailsThe AMR codec uses eight source codecs with bit-rates of 12.2, 10.2, 7.95, 7.40, 6.70, 5.90, 5.15 and 4.75 kbit/s and has a sampling frequency of 8kHz which is filtered to 200-3400 Hz. The AMR algorithm utilises link adaptation in order to be utilised with radio channel and capacity requirements.

CategoryMusic File
DescriptionAC3 is an audio file specifically developed by Dolby Digital to provide surround sound audio. The format is used for audio on many DVD and Blu-Ray media. In order for the file to be correctly decoded and output, a DVD player with a Dolby Digital compatible home cinema system is required. It became the de facto standard for surround sound, and has held that position since its inception in 1992, with it coming to home cinema in 1995.

Technical DetailsAC3 allows for separate audio to be defined for each of the 6 speakers in the standard cinema and home cinema setup. This produces the effect of surround sound to the person listening to the audio file. The six channels consist of right front, center, left front, rear right, rear left and a sub woofer.
