How to Duplicate Audio to a New Track in Audacity

Duplicating a specific portion of audio onto a new track in Audacity is a quick and non-destructive way to layer effects, create vocal doubles, or isolate audio for editing. This guide explains the fastest methods to extract and duplicate your selected audio directly onto a new track using built-in shortcuts and menu commands.

Method 1: Using the Duplicate Command (Fastest)

The fastest and most efficient way to duplicate an audio selection to a new track is using Audacity's dedicated duplicate feature, which automatically creates a new track and aligns the audio at the exact same point in time.

  1. Open your project in Audacity and select the Selection Tool (keyboard shortcut F1) from the top toolbar.
  2. Click and drag across the waveform to highlight the specific portion of the audio you want to duplicate.
  3. Press Ctrl + D on Windows/Linux or Cmd + D on macOS. Alternatively, navigate to the top menu and select Edit > Duplicate.

Audacity will instantly generate a new audio track directly beneath the original, containing only the selected segment placed in perfect synchronization with the source timeline.

Method 2: Copy and Paste to a New Track

If you want to paste the duplicated segment into a specific type of track (such as forcing a stereo track or pasting at a different point in time), you can use standard copy and paste commands.

  1. Use the Selection Tool to highlight the audio section you wish to copy.
  2. Press Ctrl + C (Windows/Linux) or Cmd + C (macOS) to copy the selection to your clipboard.
  3. Go to the top menu and select Tracks > Add New, then choose either Mono Track or Stereo Track depending on your original file format.
  4. Click inside the newly created track at the point where you want the audio to begin.
  5. Press Ctrl + V (Windows/Linux) or Cmd + V (macOS) to paste the audio.

Method 3: Split Cut to a New Track (Move Instead of Copy)

If your goal is to remove the audio from the original track while placing it onto a new track simultaneously:

  1. Highlight the desired audio section.
  2. Go to Edit > Clip Boundaries > Split New (or press Ctrl + Alt + I on Windows/Linux, Cmd + Option + I on macOS).

This removes the selected segment from the primary track and places it in the exact same time position on a newly generated track below.
