| * |
| * This section describes functions to initialize and register G.711 codec |
| * factory to the codec manager. After the codec factory has been registered, |
| * application can use @ref PJMEDIA_CODEC API to manipulate the codec. |
| * |
| * The G.711 is an ultra low complexity codecs and in trade-off it results |
| * in high bitrate, i.e: 64kbps for 16-bit PCM with sampling rate 8000Hz. |
| * |
| * The factory contains two main compression algorithms, PCMU/u-Law and |
| * PCMA/A-Law. |
