440Hz became the international standard in 1953. 432Hz is mathematically consistent with the natural harmonics found in nature — Schumann resonance, the golden ratio, the geometry of sound.
The Method
Conversion adjusts pitch by −1.818% using ffmpeg's rubberband algorithm. Tempo stays identical. Only the fundamental frequency shifts down — the feel of the track changes, not its structure.
What Changes
Most listeners report the converted track feels warmer, less harsh, easier to stay in for long periods. Whether that's physics or perception — the difference is real enough to hear.
File Output
