Convert 3GP to AU
3GP to AU Conversion Software converts 3GP files
to AU quickly and easily. The converter supports common codecs for AU
file including PCM 32-bit, PCM 32-bit Float, PCM 24-bit, ITU-T G.723 3-bit ADPCM, PCM 8-bit, PCM 16-bit, ITU-T G.721 4-bit ADPCM, CCITT a-Law (8-bit), and so on.
3GP 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 3GP?
3GP is a multimedia container format defined by the Third Generation Partnership
Project (3GPP) for use on 3G mobile phones but can also be played on some 2G and
3GP is a simplified version of the MPEG-4 Part 14 (MP4) container format, designed
to decrease storage and bandwidth requirements in order to accommodate mobile
phones. It stores video streams as MPEG-4 Part 2 or H.263 or MPEG-4 Part 10 (AVC/H.264),
and audio streams as AMR-NB, AMR-WB, AMR-WB+, AAC-LC or HE-AAC. A 3GP file is
always big-endian, storing and transferring the most significant bytes first.
It also contains descriptions of image sizes and bitrate. There are two different
standards for this format:
- 3GPP (for GSM-based Phones, may have filename extension .3gp)
- 3GPP2 (for CDMA-based Phones, may have filename extension .3g2)
Both are based on MPEG-4 and H.263 video, and AAC or AMR audio.
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.
