And so for the codec, we've selected HEVC because it meets all of these requirements.

所以我们选择了HEVC 作为编解码器，因为它符合上述所有要求。

Those include the ProRes codec and a display engine that powers ProMotion and the always-on display.

其中包括 ProRes 编解码器以及为 ProMotion 和常亮显示提供支持的显示引擎。

These values are then sent to the audio codec, which converts the digital values into an analog electrical waveform.

然后，这些值将音频编解码器，音频编解码器将字值转换为模拟波形。

If you're wondering how audio can be represented by 1's and 0's take a look at this episode on audio codecs.

如果您想知道如何用 1 和 0 表示音频，请观看有关音频编解码器的这一集。

In this scenario, the codec performs a digital to analog conversion or DAC.

在这种情况下，编解码器执行模转换或 DAC。

It was too hard to watch video content online, you had to put codecs in your browser and do all this stuff, and the company eventually went out of business in 2003.

要想在网上看视频太困难了，你不得不向浏览器加入多媒体字信号编解码器，要加入所有编解码器，最后这家公司最终在 2003 年退出了市场。

This circuit board is connected to and folded on top of a second circuit board which contains a low power stereo audio processing chip or audio codec.

路板连接并折叠于第二块路板的顶部，路板包含低功耗立体声音频处理芯片或音频编解码器。

In the scenario we just talked about, the audio codec converts the music or podcast data from a set of digital values or numbers, into an analog waveform.

在我们刚刚谈的场景中，音频编解码器将音乐或播客据​​从一组字值或字转换为模拟波形。

Codecs are used in every piece of technology we use in order to convert certain types of data into other types while compressing or decompressing the data.

我们使用的每项技术中都用了编解码器，以便在压缩或解压缩据时将某些类型的据转换为其他类型。

These technologies are the speaker, audio codecs, Bluetooth, the System on a Chip or SoC, the Printed Circuit board or PCB, accelerometers, the Lithium Ion Battery, MEMS microphones, and noise cancellation.

这些技术包括扬声器、音频编解码器、蓝牙、片上系统或 SoC、印刷路板或 PCB、加速度计、锂离子池、MEMS 麦克风和噪音消除技术。

In fact, this video you're watching is downloaded as a compressed video file, and a video codec is actively decompressing this video's data as you watch it.

事实上，您正在观看的视频是作为压缩视频文件下载的，并且视频编解码器在您观看时正在主动解压视频的据。

However, audio codecs can also do the reverse by encoding the analog signal from the microphone, into a digital set of values, which is an analog to digital conversion or ADC.

但是，音频编解码器也可以通过将来自麦克风的模拟信号编码为一组字值来执行相反的操作，即模转换或 ADC。

Well, codec stands for coding and decoding, and in general, it's either a piece of software or hardware that converts data or information from one format into another format thereby compressing or decompressing data.

嗯，编解码器代表编码和解码，一般来说，它是一种软件或硬件， 将据或信息从一种格式转换为另一种格式， 从而压缩或解压缩据。

Here, as you may have figured from this video's title and thumbnail, we're going to focus on the audio codecs, and we'll explore how sound waves can be represented digitally using just a bunch of numbers.

在这里， 正如您可能已经从本视频的标题和缩略图中了解的那样，我们将重点介绍音频编解码器，并将探索如何使用一堆字以字方式表示声波。

Now that we have a stream of millions of 6-bit  symbols yielding hundreds of megabits of data per second, in order to turn it into your favorite  TV show we use the advanced video codec, or h.

现在我们有百万个 6 位符号流，每秒可产生百兆比特的据，为了将其转换成您最喜爱的视节目，我们使用先进的视频编解码器或 H.

It was like, huh, it could be that you're just… it could be some sort of strange processing thing or it could be some codec, and it… but it's a bit baffling and a bit hard to fix.

就像，嗯，这可能是你只是......它可能是某种奇怪的处理东西，或者它可能是某种编解码器，而且它......但这有点令人困惑并且有点难以修复。

Thus far we've made a few episodes that help to explain other parts of these wireless headphones such as noise cancellation and the audio codec, and we've made even more episodes that dive into the dif-ferent parts of your smartphone.

目前为止， 我们已经制作了几集来帮助解释这些无线耳机的其他部分， 例如降噪和音频编解码器，并且我们还制作了更多剧集， 深入探讨智能手机的不同部分。
