You’ve seen to create karaoke tracks, but what if you don’t want the music? Using a similar process and good source audio, you can ditch the instruments and keep the vocals for an a cappella effect.

您已经以创建卡拉OK音轨，但是如果您不想听音乐怎么办？ 使用类似的过程和良好的源音频，您可以抛弃乐器并保留人声以获得无伴奏效果。

一个警告 (One Caveat)

Isolating the vocals works like removing vocals; in both cases we combine the original waveform with an inverted waveform to “subtract” the part we don’t want. It will leave us, in this case, with the vocal track. In order for this to work, however, you need to have a studio version of the instrumental track. Removing the vocals to get an instrumental track and then trying to isolate the vocals does not work in this case. Don’t be disheartened if you don’t have one ready. Many studios release the instrumental tracks (with and without backup vocals) for use with things like karaoke. There are plenty of places online where you can buy these tracks, like , and some singles and records even have them on the B side, so all in all, it shouldn’t be too difficult to find them for most popular artists. These full-quality instrumentals usually really work well for isolating vocals.

隔离人声就像删除人声一样； 在这两种情况下，我们都将原始波形与反相波形结合起来，以“减去”我们不需要的部分。 在这种情况下，它将使我们拥有人声的轨道。 为了使它起作用，您需要有录音室版本的乐器轨道。 在这种情况下，删除人声以获得乐器音轨，然后尝试隔离人声不起作用。 如果您还没有准备好，不要灰心。 许多录音棚发行卡拉OK等乐器音轨(有或没有备用人声)。 在网上有很多地方可以购买这些曲目，例如 ，有些单曲和唱片甚至都将它们放在B侧，因此，总的来说，对于大多数人来说找到它们并不难受欢迎的艺术家。 这些高质量的乐器通常可以很好地隔离人声。

As with center-channel (vocal) removing, the better the quality of the original tracks, the better the effect works. If you’re using MP3s, do whatever you can to avoid using tracks with a lot of clipping. This will ruin the effect over those parts. You can highlight where clipping occurs on your tracks in Audacity by going to View > Show Clipping.

与中央声道(人声)去除一样，原始音轨的质量越好，效果越好。 如果您使用的是MP3，请尽一切可能避免使用剪辑过多的曲目。 这将破坏这些部分的效果。 您可以通过查看>显示剪辑来突出显示Audacity中轨道上发生剪辑的位置。

As opposed to the final mono track you get from removing vocals, this method will leave you with a full stereo track. As such, it becomes more important to try and match the quality of both tracks before you isolate the vocals.

与您从消除人声中获得的最终单声道相反，此方法将使您拥有完整的立体声轨道。 因此，在分离人声之前，尝试匹配两个音轨的质量变得更加重要。

流程 (The Process)

Open up Audacity and import both the regular and instrumental tracks.

打开Audacity并导入常规轨道和乐器轨道。

Select the Time Shift Tool to roughly align the two properly. Next, zoom in really close, and then zoom in more. You want to see the wave function very closely.

选择“时移工具”以大致正确地对齐两者。 接下来，真正放大，然后再放大。 您想非常仔细地查看wave函数。

Take the proper time to align this as closely as you can. pick a peak or trough in the left channel of one track and match it precisely with the left channel of the other track. If the alignment isn’t right, the process won’t really work.

请花费适当的时间尽可能地使此对齐。 在一个音轨的左声道中选择一个峰或谷，并将其与另一音轨的左声道精确匹配。 如果对齐方式不正确，则该过程将无法正常工作。

Once you’ve got it as close to perfect as you can, click on the Selection Tool. Double click on the instrumental waveform to highlight all of just that one track, and go to Effect > Invert.

一旦获得尽可能接近完美的效果，请单击选择工具。 双击乐器波形以突出显示所有一条音轨，然后转到“效果”>“反转”。

Next, hit Ctrl+A to select all of both tracks. Go to Tracks > Mix and Render.

接下来，按Ctrl + A选择所有两个轨道。 转到“轨道”>“混合并渲染”。

You’ll get one combined track that should have a more diminished amplitude where the vocals were kept and the instrumentation removed.

您将获得一个组合的音轨，该音轨的振幅应进一步减小，声音会保留并移走乐器。

Give it a listen. If there’s something off, just redo it. The toughest part is in the alignment, especially if both tracks are of very different lengths.

听一听。 如果有问题，请重做。 最困难的部分是对齐，特别是如果两个轨道的长度都非常不同时。

It’s really easy to isolate the center channel for your own projects. You can study the singer’s methods this way, or listen to just the guitar solo. And, with the internet at your disposal, you should have no trouble tracking down instrumental versions of songs you like for a reasonable cost or for free.

为您自己的项目隔离中心通道真的很容易。 您可以通过这种方式研究歌手的方法，也可以只听吉他。 而且，有了互联网，您可以以合理的价格或免费的价格轻松找到喜欢的歌曲的乐器版本。
