audacity
You can use Audacity to recreate a few really common and popular effects, such as “rewinding” and that creepy ghostly pre-echo. All you need to do is start with reversed tracks.
您可以使用Audacity重现一些真正常见且流行的效果，例如“倒带”和令人毛骨悚然的幽灵前置回音。 您需要做的就是从反向轨道开始。
“反向”效应 (“Reverse” Effects)
Check out the audio clip below to hear how reverse effects sound.
查看下面的音频片段，了解反向效果的声音。

The various audio effects are simply applied in reverse, from the end of the audio to the front of it. Doing this live requires good timing and well-tuned equipment because it results in a delay between playing your instrument and hearing it from the amp. Since we’re making audio samples from recordings, things are much easier for us.
从音频的末端到音频的前面，各种音频效果都可以简单地反向应用。 进行现场直播需要良好的时机和经过良好调音的设备，因为这会导致弹奏乐器和从放大器听到声音之间存在延迟。 由于我们正在从录音中提取音频样本，因此对我们来说要容易得多。
Audacity has a “reverse” effect, and when you hit play you’ll hear the track played backwards.
Audacity具有“反向”效果，当您点击播放时，您会听到曲目向后播放。
Select what you want to edit, and go to Effect > Reverse.
选择要编辑的内容，然后转到“效果”>“反向”。
This can add a lot to your projects, especially come Halloween.
这可以为您的项目增加很多，尤其是万圣节。
背掩膜 (Backmasking)
You can also use the reverse tool to embed reversed lyrics or phrases and incorporate them into a layered track that’s meant to be played forwards. This is referred to as backmasking and is often used for secret messages in songs. Backwards audio can often sound weird or creepy on its own, but you can enhance this by changing the tempo or adding a sliding time scale/pitch shift.
您也可以使用反向工具嵌入反向的歌词或短语，并将它们合并到要向前播放的分层轨道中。 这称为回掩，通常用于歌曲中的秘密消息。 向后音频通常听起来很奇怪或令人毛骨悚然，但是您可以通过更改速度或添加滑动时间标度/音高偏移来增强此效果。
倒带 (Rewinding the Tape)
You can create a “rewind” effect by reversing the audio and going to Effect > Change Speed. Use a value of at least 100%. This will change both the tempo and speed, simulating an audio tape (remember those?) being played backwards.
您可以通过倒转音频并转到效果>更改速度来创建“倒带”效果。 使用至少100％的值。 这将改变速度和速度，模拟向后播放的录音带(还记得吗？)。
延迟和混响 (Delay and Reverb)
Delay and reverb effects lend a lot towards making the creepy echo-laden ghost-like whispers that plague horror movies. The effect is pretty easy to recreate, too. Reverse the audio, make sure there some silence at the end of the track, and add delay. Here are the settings I used to make the sound at the beginning of the article.
延迟和混响效果有助于制作令人恐怖的恐怖电影的令人毛骨悚然的回声鬼像般的耳语。 效果也很容易重现。 反转音频，确保曲目结尾处没有声音，并增加延迟。 这是我在本文开始时用来发出声音的设置。
This should give you the shallow echoes that repeat and increase in frequency up to the original sound when played forwards. Next, add some GVerb. Here are the settings I started with.
这将为您提供浅回声，当您向前播放时，它们会重复并增加频率直到原始声音。 接下来，添加一些GVerb。 这是我开始使用的设置。
You should increase the dry signal level so that the original sound still can be heard, and you can turn the early reflection level down to enhance the “sucking in” effect.
您应该增加干信号电平，以便仍能听到原始声音，并且可以调低早期反射电平，以增强“吸入”效果。
Play around with these settings to see what sounds best. Lastly, select your track and reverse it again, so that you can hear it forwards. Haunting!
试着使用这些设置，看看最听起来不错。 最后，选择您的曲目并再次将其反转，以便您可以听到转发的声音。 困扰！
Reversing tracks can help when trying to find particular sounds and effects. It comes in handy when making vocal samples for Halloween, too. Have a favorite reverse effect? Have some tips to make things sound even more creepy? Share in the comments!
当尝试查找特定的声音和效果时，倒车轨迹会有所帮助。 当为万圣节制作人声样本时，它也很方便。 有喜欢的反向效果吗？ 有一些技巧可以使事情听起来更令人毛骨悚然吗？ 分享评论！
