Most "432 Hz" tools are a slow-down trick on a file. Ours is a real-time DSP engine stitched into macOS itself. Here is the technical why — written for the people who ask.
Phase-vocoder, not naive resampling
We re-pitch by the exact ratio 432/440 ≈ 0.98182 in the frequency domain (STFT, 4096-sample window, 75% overlap, Hann). This drops the pitch by ~32 cents without stretching the time axis — so a 3-minute song stays exactly 3 minutes. Cheap converters do the opposite: they slow the file by ~1.82% and call it 432 Hz. Yours doesn't drag, and your podcasts stay in sync.
Sub-10 ms latency, system-wide
We route through a CoreAudio HAL plug-in (BlackHole 2ch as a virtual cable) and process in a real-time audio thread at 64-sample blocks @ 48 kHz. End-to-end latency under 10 ms means lip-sync stays perfect on Netflix, FaceTime feels natural, and gamers don't get headshot because of us.
Voice preservation (formant correction)
Pure pitch-shift makes singers sound like chipmunks. We extract formants via LPC (order 14) and re-impose them after pitching — so vocals stay human, dialogue stays warm, narration keeps its grain.
Apple Silicon native (Accelerate / vDSP)
FFTs run on Apple's vDSP framework, vectorized for M1/M2/M3/M4. Steady-state CPU under 2% on an M1 Air. The engine is a single Swift binary, signed and notarized, ~200 KB. No Electron. No background daemons.
Bit-exact bypass
Toggle Off and the audio is mathematically untouched — same bits in, same bits out. Useful for A/B tests and for the audiophile sceptics among us. (Hi.)

AirPods, HomePod, USB DACs, Bluetooth speakers, HDMI to your TV, multichannel aggregate devices — if macOS can play to it, Sonaria can tune it.

Open the converter"432 what? Can someone explain please?"
Short version: standard concert pitch is A = 440 Hz. Some musicians, healers and physicists have argued for decades that A = 432 Hz feels warmer, less aggressive, more resonant. That's a claim about experience, not a clinical promise.
We're not here to convince you. We built Sonaria because we felt the difference, and we wanted a tool that just works — for us, and for anyone curious enough to try. No offense if you're not.
For the curious, we keep a public library of the most serious studies, papers and interviews on the subject. Make your own mind.
The Science Behind 432 Hz
Natural Resonance
432 Hz mathematically resonates with fundamental frequencies found in nature — including the Earth's rotation and the body's own biological rhythms.
Brainwave Synchronization
Peer-reviewed studies suggest 432 Hz music can help entrain brainwaves toward alpha/theta states — supporting relaxation, focus and cognitive clarity.
Mathematical Harmony
432 Hz produces clean integer ratios that align with sacred geometry and Pythagorean tuning — generating more coherent, less dissonant waveforms.
Cellular Response
Research indicates that 432 Hz frequencies may positively influence cellular structure and support the body's natural regenerative processes.
Benefits of 432 Hz Listening
Deep Relaxation
432 Hz naturally calms the nervous system and helps lower stress-related hormones.
Enhanced Focus
Promotes alpha brainwave states associated with sustained, focused attention.
Better Sleep
Helps you fall asleep faster and supports the body's natural circadian rhythms.
Deeper Meditation
Aligns naturally with breathwork, mindfulness and contemplative practices.
Healing Support
Supports the body's own healing processes and overall wellness.
Creative Flow
Stimulates right-brain activity and unlocks artistic, intuitive expression.
One for all. All for one.
