In recent years, there has been a growing interest in the concept of tuning music to a frequency of 432Hz. Proponents of this tuning believe that it offers a more harmonious and natural sound compared to the standard tuning of 440Hz. If you’re interested in exploring this alternative tuning, this guide will walk you through the process of converting your music to 432Hz using Apple’s Pro Logic and AU Pitch, as well as the free software Audacity.

Before we dive into the specifics, it’s important to note that the process of converting music to 432Hz involves pitch shifting, which may affect the overall quality and fidelity of the audio. Additionally, not all music may sound better or more harmonious at this frequency, so it’s important to approach this with an open mind and experiment with different tracks to find what works best for you.

Step 1: Install Apple’s Pro Logic and AU Pitch Plugin
To begin, you’ll need to have Apple’s Pro Logic software installed on your computer. This professional music production software offers a range of tools and effects, including the AU Pitch plugin, which allows for precise pitch shifting. If you don’t already have Pro Logic, you can purchase and download it from the official Apple website.

Step 2: Open Your Music Project in Pro Logic
Once you have Pro Logic installed, open your music project or track in the software. You can either create a new project or work with an existing one. Ensure that the track you want to convert to 432Hz is loaded into the project.

Step 3: Apply Pitch Shift with AU Pitch Plugin
With your track loaded, navigate to the AU Pitch plugin within Pro Logic. This plugin allows you to adjust the pitch of your audio in cents. To convert your music to 432Hz, you’ll need to pitch shift it by -31.7 cents. Apply this pitch shift to your track and preview the changes to ensure it sounds as desired.

Step 4: Export the Converted Track
Once you’re satisfied with the pitch-shifted version of your track, it’s time to export it. Choose the appropriate file format and settings based on your requirements and preferences. Make sure to save the file in a location where you can easily access it for further steps.

Step 5: Download and Install Audacity
Audacity is a free and open-source audio editing software that offers a wide range of features, including pitch shifting. If you don’t already have Audacity installed on your computer, you can download it from the official Audacity website and follow the installation instructions.

Step 6: Import the Pitch-Shifted Track into Audacity
Once you have Audacity installed, open the software and import the pitch-shifted track that you exported from Pro Logic. You can do this by navigating to “File” > “Open” and selecting the file from its saved location.

Step 7: Pitch Shift A=440Hz to A=432Hz in Audacity
With your track loaded in Audacity, navigate to the “Effect” menu and select “Change Pitch.” In the dialog box that appears, enter the desired pitch shift value of -8Hz to convert A=440Hz to A=432Hz. Apply the pitch shift and preview the changes to ensure it sounds as desired.

Step 8: Export the Final 432Hz Track
Once you’re satisfied with the final pitch-shifted track, it’s time to export it. Choose the appropriate file format and settings based on your requirements and preferences. Make sure to save the file in a location where you can easily access it for playback or further editing.

In conclusion, converting music to 432Hz can be achieved using Apple’s Pro Logic and AU Pitch plugin, as well as the free software Audacity. By following the step-by-step guide outlined above, you can experiment with this alternative tuning and explore the potential benefits of a harmonious and natural sound. Remember to approach this process with an open mind and enjoy the journey of discovering new sonic possibilities.
