JAVA的声音处理方法 (转自伊氏女人)-----淘特网
- 数字音频格式有很多种，其质量与采样频率和采样精度两个参数有关。频率的表示单位为赫兹〔Hz〕，它表示每秒采样次数。采样频率越高，音质就越好。采样精度为每次采样所存储的数据数量，它决定每个数字信号所能够表示的离散振幅的数量。存储每个样本的数据越多，音质就越好。但是高品质的声音需要占用大量的内存和磁盘空间。考虑到网络带宽，在Internet连接上传输就需要花费很长的时间。对于Applet来说，保证声音文件的最小化是极为重要的。-digital audio format there are many,

- The purpose of this project is to create a different system for processing voice signals and from which we draw useful conclusions about these brands. More specifically, the system will first filter the voice signal with a pass bandwidth (chebyshe
Sound
- 由于在局域网中有足够的带宽，不需要对语音数据进行压缩，因此语音通信主要包括语音的采集、传输和播放。其中语音的采集与播放使用DirectSound接口实现，语音传输使用UDP协议实现。在多人语音通信时还需要DirectSound的混音功能。为了增强软件的实用性还要求软件能够自动获取在线用户列表，以简化用户的操作。-As the LAN has enough bandwidth, no need to compress voice data, so voice communications incl
