BMDWQI-SY
- 在音频功率放大器中，音量控制是必不可少的环节，尤其是现在用微电脑控制的多通道AV 功放，一般都采用一枚多通道音量控制芯片进行音量调节，而且根据标准要求：每个通道音量既需要总调又需要单独微调。脉冲电位器能够360 度旋转，音量调节速度可编程控制，它寿命长、不产生噪声，电路简单，这都是碳膜电位器无法比拟的。-In the audio power amplifier, volume control is an essential part, especially now with the microc

libogg
- 首先对输入音频PCM信号进行时频分析，决定MDCT的长度，即加窗，然后进行MDCT变换；同时对原始音频信号要进行FFT分析。两种变换的频谱系输入给心理声学模型单元，MDCT系数用于噪声掩蔽计算，H可结果用于音调掩蔽特性计算，共同构造总的掩蔽曲线。然后根据MDCT系数及掩蔽曲线，对频谱系数进行线性预测分析用LPC(Linear Prediction Coefficience，线性预测系数)表示频谱包络，即基底曲线(Floor Curve)；或通过线性分段逼近方式获得基底曲线。从MDCT系数中去掉
