说明: 这个是rtp库封装的 主要利用rtp进行流媒体传输,并且里面含有音频编码解码;
(This is the main package rtp library use rtp for streaming media transmission, and which contain audio codecs )

MPEG-2 Audio Simulation Software Distribution 10
================================================
$Date: 1997/01/28 12:00:48 $
This package contains source code for the MPEG-2 audio encoder and decoder
under development by the MPEG/audio software simulation ad-hoc group. The
package includes the multichannel and low sampling frequency extensions
in MPEG-2 audio.
The following table indicates the operations supported by the multichannel
software in this distribution. The multichannel encoder and decoder have been
amended compared to dist09. The bug fixes mostly fix combinations of parameters
which caused reliability problems. Furthermore both encoder and decoder are now
compliant to 13818-3.2.

The following features are NOT supported by this distribution:
* layers 1 or 3 wrt. the encoder
* layer 3 wrt. the decoder
The decoder passes all multichannel compliance bitstreams except for the
layer 3 bitstream.
The following table indicates the operations supported by the low
sampling frequency software in this distribution. The noise allocation
in the layer 3 encoding procedure has been made more robust.

The following features are NOT supported by this distribution:
* lower sampling frequencies for layer 3 in the encoder
* psychoacoustic model 1 for lower sampling frequencies in the encoder
* psychoacoustic model 1 for layer 3 in the encoder
The decoder passes all lower sampling frequency compliance bitstreams.
The package consists of the following tree of files. The contents of the
RCS and tables directories are not listed for brevity.
