wave音频文件转换成其他格式的编解码程序-wave audio file converted into other formats codec procedures

非常全的mpeg4的音频编码代码,本人进行了重新整理,适合搞音频的同志研究.-Very wide of the mpeg4 audio encoding code, I re-finishing, suitable comrades audio research.

利用声卡采集数据，可惜是delphi的。- Using the sound card gathering data, what a pity is delphi.

用C语言实现的wav文件的播放，采样，解压，和传输-Using C language to achieve the wav file playback, sampling, decompression, and transmission

实现了 从多媒体文件中抽取声音流 并写入令一个文件 对于初学者还不错-MUTIL MEDIA

在音頻/語音編解碼器，正交鏡像濾波器對經常被用來實現一個分成兩個頻帶分割的輸入信號的濾波器組。 將得到的高通和低通的信號往往是減少了2倍，給臨界採樣的原始信號的兩通道中的表示。 相關的時間序列翻轉的係數的順序，因為是線性濾波器的卷積，所以都具有相同的指數在這個總和。與此屬性的過濾器的一對被定義為正交鏡像濾波器。

自己编写的一款可以进行双路PCM语音混频的程序，针对的是16位的PCM语音数据，经过验证，比常规的混音算法质量好许多，特别是进行多路混频时，重复调用该程序也可以达到比较满意的结果。-own section can be prepared for two-way voice PCM mixing procedures, The address is 16 PCM voice data, after verification, than conventional mixing algorithm many good quality, especially for multi-channel mixer, repeat the procedure call also will be more satisfied with the results.

Wave 文件波形显示和播放-Wave document waveform display and broadcast

基于VFW的视频采集技术，可以实现实时图像的采集-based Video Capture technologies that can achieve real-time image acquisition

改变原始wav音频信号的抽样频率，并且显示处理前后声音信号的频谱.有助于帮助大家理解奈圭斯特抽样定理。-Change the original wav audio signal sampling frequency, and shows the spectrum of sound signal before and after treatment. Helps to help you understand the Nyquist sampling theorem.
