Description: 检测8K采样频率，16位PCM码流的DTMF信号
标准的DTMF双频的检测还是可以的
误差检测可能不是很精确......以后再优化
压缩包里有C源码，build出来的elf文件，原始PCM码流(Detect 8K sampling frequency, 16 bit PCM bitstream DTMF signal
Standard DTMF dual frequency detection is fine
Error detection may not be accurate...
Compressed packets have C source code, the ELF file, the original PCM stream package)
