Change Pitch of Audio (Online)

Applying a high quality pitch change to an audio file is easy in AudioNodes, and can be done in a minute, with very convincing results. This is possible even without changing the speed or length of the file.

To start, fire up AudioNodes Online (or download the desktop version for faster performance if you need it).

Import Your Audio File

On a desktop PC, you can simply drag & drop your audio file into AudioNodes and you are set. Doing so will create an Audio File Node. Alternatively, you can also:

  1. Right click on empty area
    • On touch devices: touch and hold on empty area, until the circle completes
  2. Select Audio Sources
  3. Select Audio File
  4. Right click the new Audio File Node, then select Open File (or select Properties, and load your file from the properties panel)
    • On touch devices: tap the new Audio File Node, tap the gear icon in the header, then tap the file area to open your file

Add & Connect a Pitch Shift Node

To do a pitch change, we’ll need to add a Pitch Shift Node. This is a powerful, real time pitch changer. The idea is that the audio signal will start from the Audio File Node, pass through the Pitch Shift Node, and then finally go to the main audio output:

  1. Right click (or touch and hold) on empty area, preferably somewhere to the right of your Audio File Node
  2. Choose “Audio Effects”, then “Pitch Shift”
  3. Connect your Audio File Node to your new Pitch Shift Node:
    1. Click/tap on the small blue dot to the right of your Audio File Node
    2. Click/tap on the small blue dot to the left of your Pitch Shift Node

The pitch changer is now set up, but by default, it’s not moving the pitch anywhere. You can set up the pitch now, or connect to an audio output, and tune the pitch change in real time while listening. In either case, you can do this by:

  • Dragging the top end of the blue half-circle, around the Pitch Shift Node, or
  • Right clicking the Pitch Shift Node, then choosing Properties
    • Note: on mobile, tap on the Pitch Shift Node, then tap on the gear button in the top header menu.

Output & Play

To listen to the audio from your Audio File Node, it must be ultimately connected to an Audio Destination Node. In this case, through the Pitch Shift Node.

  1. Right click (or touch and hold) on empty area, preferably somewhere to the right of your Pitch Shift Node
  2. Choose “Outputs”, then “Audio Destination”
  3. Connect your Pitch Shift Node to the Audio Destination Node you just created (the same way you connected your Audio File Node to your Pitch Shift Node)
  4. Hit play from the top bar to listen to the result
  5. Optionally adjust the Pitch Shift Node while listening to the output – you’ll be able to hear the pitch change in real time

Final Step: Render

Once you are satisfied with the results, the final step is to render the results to an output audio file:

  1. Click/tap the main menu (triple dot button in the top left corner)
  2. Choose Project
  3. Choose Export
  4. Set output settings to your liking, or leave the defaults as-is if they are sufficient
  5. Hit Start

And that’s it. Depending on the length of your file and quality settings, this process may take a few minutes.

Bonus: More Effects to Add

The way you just applied a pitch change, AudioNodes has dozens of other effects you can use, such as:
