Which is twice the fundamental frequency.

这等于基频两倍。

But your vocal chords are also producing a bunch of little vibrations on top of that big vibration of the fundamental frequency.

是你带也基本频率大震动之上产生了一系列小振动。

For a lot of instruments, the most common overtones are integer multiples of the fundamental frequency.

对于许多乐器来说，最泛音是基频整数倍。

(sample sound buzzing) So you actually heard this fundamental frequency, even though it wasn't there.

（样本音嗡嗡）因此，尽管这个基频并不存，实际上听到了它。

Guitars are also tuned so that the fundamental frequencies of their strings, correspond to set notes.

吉他也被调整以响应 基本频率，带音调。

Because, remember: the frequency of each harmonic is equal to the number of the harmonic, times the fundamental frequency.

每个谐波频率等于 谐波数乘以基频。

That's because they're both producing the same fundamental frequency that is the lowest and usually highest amplitude vibration they produce.

这是因为它们都产生相同基频，即它们产生最低且通最高振幅振动。

The number of a harmonic is equal to the number you multiply by the fundamental frequency, to get the harmonic’s frequency.

谐波数量等于乘以基频数量， 得到谐波频率。

You're creating a base tone or fundamental frequency at about 262 hertz because your vocal chords are vibrating back and forth 262 times a second.

你正创造一个大约 262 赫兹基音或基频，因为你带每秒来回振动 262 次。

The number of a harmonic is equal to the number you multiply by the fundamental frequency, to get the harmonic's frequency.

谐波数量等于你乘以数量 通过基频，求出谐波频率。

The first partial vibrates at twice the frequency of the fundamental. The next partial is three times the fundamental’s frequency, and so on.

第一部分振动频率是基本频率两倍。下一个部分是基频三倍，依此类推。

The frequency of a standing wave with two fixed ends will just be equal to the number of the harmonic, times the fundamental frequency.

两端固定驻波频率为 谐波数乘以基频。

But for a pipe that’s closed on one end, you can’t double the fundamental frequency, or quadruple it -- or multiply it by any even number.

是对于一端封闭管道，不能将基频加倍或四倍——或乘以任何偶数。

So if the signal is made up of eight samples, then the transform has eight frequency bins going from zero up to seven times the fundamental frequency.

因此，如果信号由八个样本组成，则变换具有从零到基频七倍八个频率仓。
