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

频谱分析程序
- 频谱分析技术是研究周期性现象中最为常用的一种统计分析方法，其主要是通过对一复合的波系进行数据变换，将其分解成若干振幅和相位不同的简谐波，并找出其中振幅最大的波，即该复合波中的主要频率。频谱分析的方法较多，其中最常用的是快速傅立叶变换法(FFT)-spectrum analysis techniques to study the cyclical phenomenon most commonly used a statistical an
松斋 经典功率谱估计
- 接法又称周期图法，它是把随机序列x(n)的N个观测数据视为一能量有限的序列，直接计算x(n)的离散傅立叶变换，得X(k)，然后再取其幅值的平方，并除以N，作为序列x(n)真实功率谱的估计。 -Connection also known as cycle map, it is random sequence x (n) N observational data as a sequence of limited energy, dire
tremoloEffect.txt
- Tremolo属于基于幅值变化的音效处理。基于幅值变化的音效处理相对来说较为简单而且也不易产生背景噪音。其效果即是输出的声音时响时轻，有颤动的感觉。给人一种抖动的感觉。 -Tremolo is based on changes in the amplitude of sound processing. Based on changes in the amplitude of audio processing is relative
