Got a bunch of files that need to be edited the same way? You can automate the process to save time and effort using Audacity’s Chain feature and modify tons of files at the same time.
有一堆需要以相同方式編輯的文件? 您可以使用Audacity的Chain功能自動執行該過程以節省時間和精力,并同時修改大量文件。
Batch processing is really useful when you want to make the same edits to multiple files. It comes in handy if you want to remove background noise from a series of audio lectures, remove clicks from recorded vinyl albums, or apply normalization to a bunch of sound clips. In our example, we’ll be creating an Equalizer preset and applying that to a series of wav files, then exporting them all as mp3s.
當您要對多個文件進行相同的編輯時,批處理非常有用。 如果您想消除一系列音頻講座中的背景噪音,消除錄制的黑膠唱片中的咔嗒聲或對一堆聲音片段進行歸一化處理,它會派上用場。 在我們的示例中,我們將創建一個均衡器預設并將其應用于一系列的wav文件,然后將它們全部導出為mp3。
設置我們的預設 (Getting Our Presets Set)
Let’s start by opening Audacity and go to Tracks > Add New > Audio Track.
首先,打開Audacity,然后轉到“軌道”>“添加新的”>“音軌”。

We’re only creating it so that we can edit some options that we can’t get to without a project loaded. Go to Generate > Silence.
我們只是在創建它,以便我們可以編輯一些沒有加載項目就無法進入的選項。 轉到生成>靜音。

You’ll get a prompt for the duration. Just go with the default 30; it doesn’t really matter.
您會得到持續時間的提示。 只需使用默認值30; 沒關系。

Go to Effect > Equalization.
轉到效果>均衡。

Here, you can click on intersections on the line to redraw it. This is a visual way to edit the equalizer settings. I’m tweaking some of my sitar tracks from long ago, so I’ll bump the highs and lows a bit. Of course, you should edit the EQ for whatever your needs are.
在這里,您可以單擊直線上的交叉點以重繪它。 這是編輯均衡器設置的直觀方法。 我正在調整很久以前的一些西塔琴曲目,所以我會碰到一些高點和低點。 當然,無論您需要什么,都應編輯均衡器。

That’s much better. Now click on Save As to save your preset.
那好多了。 現在單擊另存為以保存您的預設。

Give it a name. Then click OK until you’re back at the main window. Then go to File > Export.
給它起個名字。 然后單擊“確定”,直到返回主窗口。 然后轉到文件>導出。

We’re going to change the mp3 export options, so choose mp3 from the drop-down and click Options.
我們將更改mp3導出選項,因此從下拉列表中選擇mp3,然后單擊選項。

I want this down in high quality, so I chose 320 kbps. Click OK. You don’t actually have to save your fake project, so just hit cancel and close the track.
我想要高質量的,所以我選擇了320 kbps。 單擊確定。 您實際上不必保存您的假項目,因此只需單擊取消并關閉軌道即可。
創建和應用鏈 (Creating and Applying Chains)
To create a “Chain” of effects and processes, go to File > Edit Chains. You’ll see a window like so:
要創建效果和過程的“鏈”,請轉到“文件”>“編輯鏈”。 您會看到一個這樣的窗口:

Click Add to create a new chain and give it a name. Then click on Insert to add an effect.
單擊添加以創建一個新鏈并為其命名。 然后單擊插入以添加效果。

Here, double-click on Equalization to bring up the parameters. Click on the Edit Parameters button.
在這里,雙擊“均衡”以調出參數。 單擊編輯參數按鈕。

Where it says Select Curve, choose the new EQ preset we made earlier, then click OK twice. You’ll be back at the Edit Chains window, so click Insert again to add another process to our chain.
在顯示選擇曲線的地方,選擇我們之前創建的新EQ預設,然后單擊確定兩次。 您將回到“編輯鏈”窗口,因此再次單擊“插入”將另一個過程添加到我們的鏈中。

Double-click on ExportMp3. Unfortunately, you can’t edit the parameters here, which is why we did it earlier. Click OK, then at the Edit Chains window click OK. Our chain is all saved!
雙擊ExportMp3。 不幸的是,您不能在此處編輯參數,這就是我們之前進行編輯的原因。 單擊“確定”,然后在“編輯鏈”窗口中單擊“確定”。 我們的連鎖店已全部保存!
To actually batch process files, we need to go to File > Apply Chains.
要實際批處理文件,我們需要轉到文件>應用鏈。

You can select a chain and apply it to your current project as well, but for our guide, let’s apply it to a couple of different files.
您可以選擇一個鏈并將其也應用于當前項目,但是對于我們的指南,讓我們將其應用于幾個不同的文件。

Then, sit back and watch Audacity work for you!
然后,坐下來觀看Audacity為您服務!

Batch processing comes in handy when you want to repeat long effect chains to multiple files, or even for common functions in standard editing. It’s perfect for low-maintenance changes, like cleaning up dictations and exporting them in compressed formats. Share your uses and favorite effects in the comments!
當您想要將長效鏈重復到多個文件時,甚至對于標準編輯中的常用功能,批處理都非常方便。 它是低維護更改的理想選擇,例如清理口述并以壓縮格式將其導出。 在評論中分享您的使用和喜愛的效果!
