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.

File extension.aac
CategoryMusic File
DescriptionAAC is similar to MP3. It essentially cuts out, or compresses, information that the human ear cannot pick up thereby making digital files smaller and more easily managed and therefore quicker to download. AAC is about half the size of MP3 but with better quality. It is at least one tenth the size of CD digital data. Apple are the biggest users of this format and if you have an iPod or iPhone then you will have come across this format as it is iTunes default audio format.

Technical DetailsAAC is similar in concept to MP3 but goes further. It too compresses digital audio files but to a bigger degree. It is also part of the MPEG-4 standard, it is most widely used to create small digital audio files. The current variant is specified in ISO/IEC standard 14496-3. Like MP3, AAC is a lossy algorithm. The human hearing system cannot hear quiet sounds in the presence of loud sounds of a similar frequency; for example, a voice conversation cannot be heard while an aeroplane flies low overhead. This is known as auditory masking, this allows the discarding of data with minimal loss of quality.
