What is a 432 Hz Converter?
A 432 Hz Converter is a tool that performs pitch shifting to change the reference tuning of audio. Many recordings are produced with A4=440 Hz (often called “standard tuning”). A conversion to A4=432 Hz shifts the whole audio down slightly, while keeping the musical relationships intact.In simple terms: the converter creates a new audio file with the requested tuning so you can listen, compare, and use it in your own playlists or projects.
How does 440 Hz to 432 Hz conversion work?
The conversion is done by changing pitch by a small ratio between the two reference points (440 and 432). A good converter applies pitch shifting in a way that aims to keep the audio usable and musical.The audible result can vary depending on the source material (dense mixes, strong transients, vocals, and heavy compression can react differently). That is normal for any pitch process.
440 Hz to 432 Hz conversion math (quick facts)

- Pitch offset: approximately −31.77 cents
- Change: approximately −1.818%
Pitch shift vs. playback speed
This 432 Hz Converter uses pitch shift to change tuning while keeping tempo and duration unchanged (unlike playback-speed changes, which alter length).432 Hz Converter Online vs. Windows Software

Tip for best results
If you are comparing 440 Hz and 432 Hz versions, try to keep playback volume consistent and use the same headphones or speakers. Small pitch differences are easier to notice on sustained notes, vocals, pads, or instruments with stable tone.Supported audio formats and presets
The Windows converter supports these popular audio formats: MP3, WAV, M4A, AAC, AIFF/AIF, FLAC.Besides 432 Hz, some converters offer frequency presets that are commonly referenced online, including sets often listed as “Solfeggio” frequencies. If you need a specific target frequency, look for a “custom frequency” option in the converter you are using.

FAQ: 432 Hz Converter
What does “A4=432 Hz” mean?

No. Retuning an instrument changes the instrument itself. A 432 Hz Converter processes an existing recording to shift its pitch so the file plays back in the chosen tuning.Will converting to 432 Hz improve audio quality?
Conversion changes tuning, not the original recording quality. Quality depends on your source file and the conversion method. For best results, start with a high-quality file (for example a lossless format when available).Which option should I use: Online or Windows?
