Presets Explained (Exact Conversions)
432 Hz (A4 440 → 432) with the 432Hz converter
Most music is tuned with A4 = 440 Hz as the standard reference pitch. The 432 Hz preset shifts that reference so that A4 becomes 432 Hz — specifically:
• 432 Hz → 440.000 → 432.000
In simple terms: if a track is aligned to the common 440 Hz tuning, this preset retunes it down so the "A" reference matches 432 Hz.
Solfeggio Presets (Exact Reference → Target)
These presets shift pitch using a predefined reference frequency → target frequency mapping:
- 174 Hz → 174.614 (F3) → 174.000
- 285 Hz → 277.183 (C#4) → 285.000
- 396 Hz → 391.995 (G4) → 396.000
- 417 Hz → 415.305 (G#4)→ 417.000
- 440 Hz → 440.000 (A4) → 432.000
- 528 Hz → 523.251 (C5) → 528.000
- 639 Hz → 622.254 (D#5) → 639.000
- 741 Hz → 739.989 (F#5) → 741.000
- 852 Hz → 830.609 (G#5) → 852.000
- 963 Hz → 987.767 (B5) → 963.000
What Does "Reference Frequency" Mean?
A reference frequency is the starting pitch standard the preset assumes your audio is based on. The converter then shifts the entire audio up or down by a ratio so that the reference value becomes the target value.
Example:
- Reference: 440.000 Hz
- Target: 432.000 Hz
- The converter applies a pitch shift so that what would be "A = 440 Hz" is moved to "A = 432 Hz."
This is why each preset shows two numbers:
reference → target (what it assumes → what it converts to).
