What is AU?
The Au file format is a simple audio file format introduced by Sun Microsystems.
The format was common on NeXT systems and on early web pages. Originally it was
headerless, being simply 8-bit u-law encoded data at an 8000 Hz sample rate. Hardware
from other vendors often used sample rates as high as 8192 Hz, often integer factors
of video clock signals. Newer files have a header that consists of six 32-bit
words, an optional information chunk and then the data (in big endian format).
Although the format now supports many audio encoding formats, it remains associated
with the u-law logarithmic encoding. This encoding was native to the SPARCstation
1 hardware, where SunOS exposed the encoding to apps through the /dev/audio interface.
This encoding and interface became a de facto standard for Unix sound.
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.
