本文主要介紹音頻處理的實現以及它有那些功能和這些功能實現的流程圖。在這里對音頻的處理就是對語音的處理,對語音的處理是建立在數字音頻的基礎之上的,也就是對采樣點進行處理。對音頻處理系統是在VISUAL C++ 6.0的平臺上開發的,主要是用消息映射函數響應各種功能操作,主要是完成文件的打開文件,新建文件,保存文件,播放,剪切,粘貼,拷貝,放大,縮小,鼠標雙擊,拖動,單擊操作等。在消息映射函數中根據流程圖編寫各種操作代碼并不斷的調試,最后實現程序處理音頻的功能。
在VISUAL C++ 6.0的平臺上,采用上述方法來編輯音頻處理軟件。最后系統調試成功,并且能夠對語音進行上述功能的操作,達到一定的處理效果。

Abstract
The achievement of sound processing, the functions of the software, and process chart of achieving these functions are mainly introduced in this article. The audio processing is just the sound processing, here. Digital audio is the basic of the audio processing. This process is also like dealing with samples. Developing the audio processing system was based on Visual 6.0 platform. The functions of mapped message were responsed for varieties of operations, such as opening the file, saving the file and creating the file, playing, clipping the wave and pasting the wave, making the wave larger or smaller, mouse double clicks, and click, mouse moving. Then depended on the process chart edit the code for varieties of operations to achieve the foundations of the system in the mapped message functions and debugged the code. At last the foundations of audio processing have achieved.
On the Visual 6.0 platform, edited the audio processing system with the method which referred above. Last, the system has finished and can deal with the wave files. And the effect was also achieved.
