关于声卡采集的一个程序，可做FFT，利用声卡做采集卡，可做声音的频谱分析。...

libdca is a free library for decoding DTS Coherent Acoustics streams. The code is written by Gildas Bazin and was based on the a52dec project. It is released under the terms of the GPL license. The DTS Coherent Acoustics standard (ETSI 102 114 v1.2.1), as published by the ETSI, is available here (http://pda.etsi.org/pda/queryform.asp).-libdca is a free library for decoding DTS Co.

fft 实施，易于使用，包括修复点代码。我还举了一个例子，向您展示如何使用 此代码 wav 开发的 Linux 操作系统，但它也可以种植在窗口 （不需要更改代码，只是在 VC 中创建 dsp)

语音信号利用LBG训练方法，实现在特征AR域的聚类，制作码书。码书大小，维数，失真限可调。可以用较小的误差重建原始信号。

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!

lm1972 volune控制器数据表您可以使用mcu控制音频音量。ex、pic、avr、arduino等

这是一个MP3源码,给那些要用的朋友使吧,希望大家用的开心-MP3 this is a source for people who use it to make friends, I hope that people will use the unhappy

对音频信号的无损压缩算法。比MP3的质量还要高的多的音频压缩算法！-right audio signals in the lossless compression algorithm. The quality than MP3 but also the high number of audio compression algorithm!

一个比较小巧的媒体播放器，自己可以在此基础上添加需要的功能-a more compact media player, and they would like to add on the basis of the functional needs
