This is file to compress Audio using CVSD at 16 Kbps

CRC code for CCIT 16 CRC

dtmf 拨号程序，Pocket PC ，vc 工程演示(dialDTMF a Pocket PC (Pocket Contact) plugin to dial telephone numbers using DTMF s (aka Dual Tone Multi-Frequency) (tested under PPC2000 MIPS, PPC2000 ARM, PPC2002 ARM, Xscale WMPPC2003 and WM2003SE, WM5- if you want your processor supported either build the exe s yourself from CVS or email me and I may look into it). There is a listed of known working hardware in the FAQ.)

双通道语音增强算法，消除环境噪声。采用归一化自适应方法，噪噪声抵消10dB，语音保持较好可懂度。(The dual-channel speech enhancement algorithm to eliminate ambient noise. Using normalized adaptive noise noise offset by 10dB, and the voice to maintain good intelligibility.)
