Select song
Select a local music file, a file from a website, or a file from OneDrive or Dropbox. Supports mp3, aac, mp4, wav, flac, ogg, m4a, avi, and many more.
Choose frequencies
In most cases the source frequency is 440Hz standard A. Select "432 Hz" as target to convert to 432 Hz music. More details about music frequencies can be found here.
Output options
Select the output format and processing method.
Two different algorithms are provided (one time-based and one frequency-based). Depending on the input music one or the other algorithm produces better results but it cannot be generally said that one algorithm is better than the other. If the resulting audio sounds distorted then try the other algorithm.

Frequently asked questions
What does converting to 432 Hz actually do?
The converter slightly shifts the pitch of your music so that the note A4 lands on 432 Hz instead of the 440 Hz standard — while preserving tempo and audio quality.
Which source frequency should I choose?
Nearly all commercial music is tuned to 440 Hz — keep the default unless you know your song uses a different tuning.
Which algorithm should I pick?
Try the default time-based method first. If the result sounds distorted, convert again with the frequency-based method.
Is the conversion really free?
Yes. The online tool is free and ad-supported. For batch conversion of your whole music collection and offline use, check out our desktop app.
