PortAudio是一个跨平台的音频库，可以用来开发音频信号分析软件，压缩包里是我做的DELPHI下使用PortAudio动态库的实例。-PortAudio is a cross-platform audio library that can be used to develop the audio signal analysis software, compression bag that I do use PortAudio dynamic libraries DELPHI examples.

i writing an free losless audio coder, faster on old 486 than flac or ape decoding on pentium 233 MHz !!! the program working, and compression ratio is equal to flac / ape ... On pentium 233 MHz flac decompress time is 26 sec of enya_.wav . ape is more than 45 sec... :) approx 14 sec coding enya.wav with pkzip, and my routines not have completed. My hope is 4 sec compression time, if completing, and decompressing a 16 bit stereo 44100 Hz is real time on 80286 cpu !!! PLEASE HELP ME ! i am an hungarian programmer, and i cannot wrtite in english perfectly. i not have time for write code for incoming 16 bit variable contents ! i want variable bit size putting into 8 bit foam. the 16 bit variable containing e.g. 7 bit valuable data, and 8 of this data must be storing into 8 bit datas. (code need 24 .. 2 bit incoming packing into 8 bit data.)-i writing an free losless audio coder, faster on old 486 than flac or ape dec

sndpeek is just what it sounds (and looks) like: real-time 3D animated display/playback can use mic-input or wav/aiff/snd/raw/mat file (with playback) time-domain waveform FFT magnitude spectrum 3D waterfall plot lissajous! (interchannel correlation) rotatable and scalable display freeze frame! (for didactic purposes) real-time spectral feature extraction (centroid, rms, flux, rolloff) available on MacOS X, Linux, and Windows under GPL part of the sndtools distribution. -sndpeek is just what it sounds (and looks) like: real-time 3D animated display/playback can use mic-input or wav/aiff/snd/raw/mat file (with playback) time-domain waveform FFT magnitude spectrum 3D waterfall plot lissajous!

语音信号处理具有很多的数字信号处理方法和 matlaba 函数的数学信号处理代码的一个重要分支。一些基本的方法的第一至第四章的语音信号处理、 预处理和特征的第五至第九章介绍了语音信号的提取。包括谱减法、 维纳方法、 子空间算法和 MMSE 算法。章相结合的各种参数，介绍了合成语音信号检测、 速度和讲话口气信号处理、 语音合成 TDPSOLA 还介绍了。

用vc做的简单的音乐播放器，有滑动条及时间显示，需要的可以参考一下，功能比较齐全
