Short-time-analysis
- 语音处理，包括短时能量、短时幅度、过零率、宽带宽带普及窄带普。-Speech processing, including short-time energy, short-time amplitude and zero crossing rate, broadband broadband penetration narrowband Cape.
dtmf
- 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 wh
PCM-Voice
- 语音压缩，使用pcm编码，计算压缩比，信噪比，保留能量-Voice compression, pcm Encode to calculate the compression ratio, signal to noise ratio, retained energy
