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 M4A?
MPEG-4 Audio. Because of its exceptional performance and quality, Advanced Audio
Coding (AAC) is at the core of the MPEG-4, 3GPP and 3GPP2 specifications and is
the audio codec of choice for Internet, wireless and digital broadcast arenas.
AAC provides audio encoding that compresses much more efficiently than older formats,
such as MP3, yet delivers quality rivaling that of uncompressed CD audio.
