It's sort of the vocabulary of spin imprinted on this waveform.

可以说这就是旋转 在形图上留下只言片语。

This is a bunch of stuff in between two long pauses.

这是两个长停顿之间形。

He said this is because all the wireless technologies use the same waveforms to radiate energy.

他说，这是因为所有无线技术都使用相同形来发射能量。

Again, the bigger the dipole, the bigger the negative deflection.

同样，双极子（电压差值）越大，负形也就越大。

So if we go back to our simple wave.

所以如果我们回到简单形。

These are the waveforms of those two sounds, as captured by a computer’s microphone.

这些是两种声音形，由电脑麦克风捕。

Sound was first recorded by dragging a vibrating needle through wax to draw the waveform.

声音最初是通过在蜡中拖动根振动针来绘制形而得以记录。

It helps to focus your mental waveform as if there was any such thing.

它有助于集中你精神形，仿佛真有其。

I need to see his underlying rhythm.

我要看下他基础形。

So instead, both tracks are actually cut at a 45-degree angle on either side of the groove.

因此，实际上两条音轨并不是像我在视频中所说那样，分别切割成上下和左右形，而是两边都以45度角切入凹槽两侧。

The ventricular contraction is seen as a QRS complex, and the ventricular repolarization, and therefore it's relaxation, is seen as a T-wave.

心室收缩以QRS复合群形式展现，心室复极以及因此发生舒张形，则视为T。

It's kind of like taking the recording of the entire party and pulling out a particular voice's waveform.

这有点像从整个派对录音中提取出某个特定声音形。

Then you could play back that recording on the wax cylinder that you had drawn the waveform into.

随后，你可以在绘制了形蜡筒上回放那段录音。

And these numbers are exactly what gets stored in a WAVE file!

这些数字正是存储在形文件中内容！

But yeah, on the first front, it would be nice if they had a way to like find waveform.

是，首先，如果他们能有个查找形方法就好了。

And, as we mentioned, every data point, or sample of the analog audio waveform, is 23 microseconds apart.

并且， 正如我们所说， 每个数据点，即模拟音频形采样，间隔为23微秒。

This conversion from waveform to frequencies is done with a very cool algorithm called a Fast Fourier Transform.

这个从形到频率转换是通过个非常酷算法——快速傅里叶变换来完成。

Let's get back to our long list of digital values that represent the analog waveform.

让我们回到代表模拟形长长数字值列表。

You can see how the shape of the grooves closely resembles the waveforms we have been talking about.

你可以看到沟槽形状与我们讨论过形非常相似。

A minute later, Ove turns up triumphantly in the doorway, dragging a gigantic piece of corrugated iron, as big as a living room rug.

分钟之后，欧维得意地拽着块巨大形铁皮出现在门廊外，那铁皮跟客厅用地毯差不多大。
