Convert AAC to AU
AAC to AU Conversion Software converts AAC files
to AU quickly and easily. The converter supports common codecs for AU
file including PCM 32-bit, PCM 16-bit, PCM 8-bit, PCM 64-bit Float, CCITT a-Law (8-bit), PCM 32-bit Float, ITU-T G.723 3-bit ADPCM, ITU-T G.723 5-bit ADPCM, and so on.
AAC to AU Conversion Software is very easy to use
and supports batch conversion. It is full compatible with both 32-bit
and 64-bit editions Windows 10/8/7/Vista/XP/2000.
What is AAC?
Advanced Audio Coding (AAC) is a standardized, lossy compression and encoding
scheme for digital audio. Designed to be the successor of the MP3 format, AAC
generally achieves better sound quality than MP3 at many bit rates.
AAC has been standardized by ISO and IEC, as part of the MPEG-2 & MPEG-4
specifications. The MPEG-2 standard contains several audio coding methods, including
the MP3 coding scheme. AAC is able to include 48 full-bandwidth (up to 96 kHz)
audio channels in one stream plus 15 low frequency enhancement (LFE, limited to
120 Hz) channels and up to 15 data streams. AAC is able to achieve indistinguishable
audio quality at data rates of 320 kbit/s (64kbit/s/channel) for five channels.
The quality is close to CD also at 96 kbit/s (48kbit/s/channel) for stereo.
AAC's best known use is as the default audio format of Apple's iPhone, iPod,
iTunes, and the format used for all iTunes Store audio (with extensions for proprietary
digital rights management).
AAC is also the standard audio format for Sony's PlayStation 3 and is supported
by Sony's Playstation Portable, latest generation of Sony Walkman, Sony Ericsson
Walkman Phone, Nintendo's Wii (with the Photo Channel 1.1 update installed for
Wii consoles purchased before late 2007) and the MPEG-4 video standard. HE-AAC
is part of digital radio standards like DAB+ and Digital Radio Mondiale.
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.
