Description: 本程序用于检测音频文件中是否具有DTMF信号，若有则将其检出。
程序首先使用Goertzel算法求出以FRAMESIZE（默认200）为大小的一帧数据在8个DTMF频点上的能量。
对Goertzel算法的改进，对于系数的计算不是采用2*cos[2*pi*k/N]，而是采用2*cos[2*pi*fn/fs],这样能够降低误差。
确定了8个频点的能量后运用一系列判决门限来确定有没有DTMF信号，以及信号是什么。
-This procedure used to detect whether an audio file with a DTMF signal, if so, what will be its detection. Procedures to derive the first use of Goertzel algorithm to FRAMESIZE [default 200] for the size of data in an eight point DTMF frequency energy. Of the Goertzel algorithm for the calculation of coefficients instead of 2* cos [2* pi* k/N], instead of using the 2* cos [2* pi* fn/fs], this can reduce the error. Identified eight frequency energy use after a series of sentences to determine the threshold has no DTMF signal, as well as the signal is.

Description: The MT8870D/MT8870D-1 is a complete DTMF
receiver integrating both the bandsplit filter and
digital decoder functions. The filter section uses
switched capacitor techniques for high and low
group filters the decoder uses digital counting
techniques to detect and decode all 16 DTMF tonepairs
into a 4-bit code. External component count is
minimized by on chip provision of a differential input
amplifier, clock oscillator and latched three-state bus
interface.-The MT8870D/MT8870D-1 is a complete DTMF

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)
