440 Hz Pitch to Verdi A4 432 Hz Macro

Post by jmrsudbury » Sat Jun 12, 2021 5:11 pm

I recently heard about scientific pitch and Verdi A pitch which uses a 432 Hz instead of 440 Hz that the ISO decided on. I know about Larouche already. I wanted to try 432 anyway, so I wrote a macro today to convert my MP3 files. The online help suggests to not exceed 500 files at a time when you use this macro. You can save this to a text file then import this macro and use the Files button to select which MP3s to convert. The output goes to the Documents\Audacity\macro-output\ folder on my system.

SelectAll:
ChangePitch:Percentage="-1.831" SBSMS="0"
ExportMp3:

Have you tried 444Hz using "Change Speed" rather than "Change Pitch" (speed multiplier 1.009), and exporting as WAV?
