Audio Codec Codec是什么意思 (解码器英文)

Audio Codec，就是音频编解码器。

Codec就是编解码器，是编码器encoder与解码器decoder的混合体。音频编解码器，是指一种能够对数字音频流进行编码和解码的设备或计算机程序。就软件层面来说，音频编解码器就是根据特定的音频文件格式或流媒体格式、对数字音频数据实现压缩/解压缩的计算机程序。

扩展资料：

在软件层面，音频编解码器是一个执行算法的计算机程序，能压缩与解压缩数字音频数据到音频文件或流媒体音频编码格式。

该算法的目的是保证质量的前提下使用最少的比特表示高保真音频信号。这可以有效地减少存储空间和传输已存储音频文件所需的带宽。大多数编解码器是实现为一个具有接口的库供一个或多个媒体播放器使用。

在硬件层面，音频编解码器指一个能编码模拟音频到数字音频和解码数字音频到模拟音频的独立设备。换种说法，它包含运行在同样时钟的模数转换器（ADC）和数模转换器（DAC）。这在声卡中被使用以支持音频输入和输出。

求解码器英文翻译！

The decoder (Decoder), is one kind of the hardware/ software equipment importing the form simulating a video signal and it changing into the digital signal, further, to compress and transfer. Mp3 , ac3 , dts resembling video frequency mpeg4 , VF wait , these coders can store primitive data compression , are a code form in common use a short while ago, the code form , general family basic still having some of special field can not use arriving at. Video frequency and VF need to use to decipher software then for replaying these on the household setout or the computer , are called a plug in connector in general. For instance , decipher plug in connector of mpeg4 ffdshow,decipher plug in connector of ac3 ac3fliter waits. Only when having installed the decipher various plug in connector, your computer ability replays these images For the what be spoken decoder is soft in the software decoder and the hardware decoder computer the decoder, unties the decoder classification decoder mark namely by software method out VF video frequency data. That responds to relatively is DVD and vcd machine and , they belong to the hardware decoder. The decoder existence is to compress because of the VF video frequency data memory is going to pass first , the data amount is very ample otherwise , compresses but needing to store maximal mass VF video frequency data by the fact that certain code , ability use coming minimal capacities. Be going to decipher first by the fact that the decoder is in progress therefore when needing to carry out playing on the data.

请问一下DAC解码器有什么用

dac解码器又称为数字模拟转换器，英文名digital

to

analog

converter，英文缩写：dac，所以国内俗称dac解码器。

dac解码器是一种将数字信号转换为模拟信号（以电流、电压或电荷的形式）的设备。在很多数字系统中（例如计算机），信号以数字方式存储和传输，而数字模拟转换器可以将这样的信号转换为模拟信号，从而使得它们能够被外界（人或其他非数字系统）识别。
