自动调音是如何实现的

How Auto-Tune Works

音调是由空气按照一定的频率
A pure tone is a vibration of air back and forth
来回振动产生的
at a certain frequency.
听起来就像这样
And it sounds like this.
[音调]
[tone]
如果你想把这个声音调高
If you want to raise the pitch of that tone,
你可以加快它的振动频率
you can speed up those vibrations.
[高短音]
[higher shorter tone]
但是由于振动频率变快了 声音不会持续那么长
But because you’ve sped the vibrations up, that tone doesn’t last as long.
如果让频率变慢
Slow it down…
[低长音]
[lower longer tone]
声音的持续时间就会变长
…and that tone will go on for longer.
音调校准或自动调音就是这个原理
Pitch correction, or auto-tune, is clever.
它通过改变振动频率来
When it changes a note that someone’snot quite sung correctly,
调整某个人唱得不准的音符
it changes the speed of the vibrations,
但同时还要增减一些振动时长
but it also adds or removes some vibrations
以保持声音的持续时间一致
so the duration stays the same.
当然这不是完整的答案
Except that’s not quite the full answer.
因为音符听起来不是这样的:
Because musical notes don’t sound like this:
[声调]
[tone]
而是这样的
They sound like this.
你好~你好~
– ♫ Hello ♫- ♫ Hello!
你好~你好~
♫ – ♫ Hello… ♫- ♫ Hello~ ♫ Ladies,
女士们 先生们以及所有观众们
gentlemen,and all in between,
以下是格雷戈里兄弟的时间
the Gregory Brothers.
人类的声音不能唱出纯音
Human voices don’t sing pure tones
人类的声音有太多频率
They’re stacked with many frequencies
这些与自然共鸣的声音
these natural resonating overtones
听起来像仅是人耳中的一个音调
sound like a single pitch to human ears
我曾花费数个小时尝试理解
I spent hours trying to understand
纠正音调的工作原理
how pitch correction actually works
但我学的是语言学
but my degree’s in linguistic
我还没准备好
and I wasn’t prepared
这疯狂的方程式
for equations that were this berserker
这个秘密叫做傅里叶变换式
the secret is math called a Fourier transform
它需要被交织在一起的频率
it takes the frequences that were interwined
分开频率 找出频率 分离频率
splits them up, identifies them, isolates them
然后软件就可以真正改变它们
then software can change them live, in real time
新的软件可以改变和弦中的不同音符
the newest software can change different notes inside a chord
你可以把声音变成钢琴音 吉他音和合唱音
you can tune piano,guitars,choirs
对我来说如此高级 如魔法一般
to me,it’s so advanced, it might as well be magic
但软件不能自己写曲
but it can’t write a song
我们还是需要人的才能
some talents still required
还是需要人的才能
some talents still required
[未修音的歌声]
[effects and auto-tune fade out]
[拉长音]
[note continues]
[呼气声]
[gasps]
我知道我们跑题了 但是我觉得这歌听起来很棒
– I know we’re wandering off, but I thought that sounded pretty good.
对我来说确实很好听
– That certainly worked for me.
[笑声]
[laughter]
-很优秀-很有力量的声音
– That’s good.- It’s a powerful note.
刚刚的长音有点伤到我了 有点难受
– That hurt! That actually hurt.
