Description: With the increasing demand of digital telephone and data communication capacity, and do not want to significantly reduce the quality of voice signal transmission, in addition to improving communication bandwidth, voice signal compression is an important measure to improve communication capacity. Another example that illustrates the importance of voice data compression is that users cannot use a 28.8 kb/s modem to receive 64 kb/s voice data stream over the Internet, which is a mono-channel, 8-bit/sample, 8 kHz voice data stream.
