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 M4R?
M4R is the standard file format for Apple iPhone ringtones. The M4R is encoded
with Advanced Audio Coding (AAC). The AAC is a standardized, lossy compression
and encoding scheme for digital audio. AAC has been standardized by ISO and IEC,
as part of the MPEG-2 and MPEG-4 specifications.
