- 通过 TopByteLabs 公司开发的 MP3 AddIn,您就可以不必转换格式而直接把 MP3 文件插入PowerPoint 演示文稿中。 MP3 AddIn 在后台修改 MP3 文件的头部并自动重命名该音频文件,从而使得 PowerPoint “认为” 这就是一个 WAV 文件。这样做最大的好处是文件大小几乎不变。新生成的 WAV 文件只比原来的 MP3 文件增大了两个字节。而真正的文件格式转换会导致音频文件大小的急剧增加。利用 MP3 Addin 你仍然可以享受到 MP3 文件的高
CDMAchannel
- 语音编码为信源编码,是将模拟信号转变为数字信号,然后在信道中传输。在数字移动通信中,语音编码技术具有相当关键的作用,高质量低速率的话音编码技术与高效率数字调制技术相结合,可以为数字移动网提供高于模拟移动网的系统容量。目前,国际上语音编码技术的研究方向有两个:降低话音编码速率和提高话音质。-Speech coding for source coding is the analog signal into a digital signal, and then in the channel trans

- 用于控制音质的NF型调制控制电路,因仅能进行低音和高音的增强和衰减,所以不能进行细微的频率特性的补偿。述有,如果想使可听频带域的任意频率均可变,一般使用被称为图形均衡器的装置。这里使用DSP的例子在不断增加,如果要使用简单的电路则使用OP放大器较好。这种图形均衡器是将补偿的中心频率分割为5~7份,分别进行控制,由5个RLC电路组成,十分实用。分割的各个频率是以可听频率范围为对称轴均等分配而决定。-NF-modulation control circuit to control the sound
