432Hz instantly calms your mind. One click to escape 440Hz stress.
33 volunteers saw 4.79 BPM heart rate drop in 20 minutes (Science below ↓)
A personal discovery that changed everything
I love listening to music while working - it's essential to my flow. But something always felt... off. The pitch seemed slightly too high, creating this subtle tension that scattered my focus. I'd find myself constantly skipping tracks, adjusting volume, never quite settling into deep work.
While researching why certain music disrupted my focus, I discovered the world of sound frequencies. Most modern music is tuned to 440Hz - a standard pushed in 1939. But before that? Musicians used various frequencies, with 432Hz being particularly common. The rabbit hole went deep.
I tried everything - 528Hz, 396Hz, 741Hz. But 432Hz was different. Music suddenly felt... right. The subtle tension vanished. Background instruments I'd never noticed became crystal clear. Even better, I found three peer-reviewed studies backing what I was experiencing - measurable reductions in heart rate and stress.
I built a Chrome extension to automatically convert YouTube audio to 432Hz. No more downloading special tracks or searching for "432Hz versions." Just click once and any YouTube video - music, podcasts, tutorials - shifts to this calmer frequency. My focus sessions went from 45 minutes to 2+ hours.
Now 432Hz is my daily tool. Same playlists, same music I love, but pitched to support deep focus instead of disrupting it. When developer friends tried it and had the same "aha" moment, I knew this needed to be shared. FLOWAVE exists because everyone deserves to experience their favorite music at its most focused frequency.

Clinical Evidence:
• 4.79 BPM heart rate reduction measured at 20 minutes (p=0.05) in 33 volunteers [PMID: 31031095, 2019]
• Participants reported being "more focused" and "generally satisfied" during 432Hz sessions
• 54 emergency nurses reduced anxiety scores by 5 points (STAI scale) in just one shift [PMC9534204 / PMID: 35545982, 2022]
• 2.7 breaths/minute respiratory rate reduction (p=0.000)
• 3.8 mmHg systolic blood pressure drop (p=0.031)
• Measured during actual emergency room shifts - real-world stress conditions
• Sleep scores improved +3.6 points (p=0.02) in spinal cord injury patients [PMID: 33263352, 2020]
• 440Hz showed no significant improvement (-1.50, p=0.34)
• 30 minutes of daily listening was sufficient for measurable benefits
• Aligns with the Schumann Resonance (Earth's electromagnetic frequency)
• Creates more harmonic resonance patterns in water molecules
• Mathematically coherent with natural patterns (divisible by 2, 3, 4, 6, 8, 9...)
• The standard 440Hz was imposed in 1939 - before that, musicians used various natural frequencies
All studies were double-blind, peer-reviewed, and published in medical journals. Participants couldn't consciously tell the difference between frequencies, but their bodies measured significant improvements.
Yes! While some claim "most people can't hear the difference," our users report feeling calmer, more focused, and less anxious within minutes. The frequency affects your nervous system even if you don't consciously perceive the pitch change. Studies show measurable physiological changes - your body knows the difference even when your mind doesn't.
Absolutely! FLOWAVE transforms audio from ANY source in your Chrome browser - YouTube, Spotify Web Player, Netflix, Zoom calls, podcasts, meditation apps, binaural beats, and thousands of other sites. If it plays audio through Chrome, we can convert it to 432Hz in real-time.
Zero data collection, period. Unlike other apps that track your listening habits for ads, all FLOWAVE processing happens locally in your browser. No audio data, no usage analytics, no behavioral tracking. We don't even know what you're listening to. Your frequency optimization journey stays completely private.
After your trial, you'll choose a plan to continue your frequency optimization journey. The 2 hours are cumulative - use them across multiple sessions to truly experience the stress-reduction and focus benefits. Most users upgrade within their first hour after feeling the difference.
The studies are real and peer-reviewed with measurable physiological effects documented in controlled clinical trials. While skeptics exist, the measurable heart rate reductions, improved sleep scores, and anxiety relief in clinical settings aren't placebo. Even if some benefits were psychological, reduced stress is reduced stress. Your nervous system responds to frequency whether your logical mind "believes" or not.
Perfect for all three! Biohackers use 432Hz for deep meditation sessions, entrepreneurs use it during focused work blocks, and many report better sleep when listening to 432Hz music before bed. The frequency naturally reduces cortisol and promotes alpha brain wave states ideal for relaxation and concentration.
Good question! True 432Hz content is rare - most "432Hz" videos on YouTube are just 440Hz with marketing claims. Plus, you'd miss out on your favorite artists, podcasts, and content. FLOWAVE lets you transform ANY audio to authentic 432Hz, giving you unlimited access to your preferred content in the optimal frequency.
Before the 19th century, there was no universal tuning standard - orchestras used frequencies ranging from 400Hz to 470Hz.
The Industry Push: The standardization to 440Hz was heavily influenced by J.C. Deagan, a musical instrument manufacturer with U.S. Navy connections. While some researchers claim the Rockefeller Foundation funded the American Federation of Musicians around 1910, the AFM actually adopted 440Hz at their 1917 convention in New Haven [Source]. The Rockefeller Foundation was indeed funding acoustic research and radio standardization in this era, particularly for military and propaganda analysis by the 1930s. However, no documented evidence directly links their grants to the 440Hz adoption. Using his wealthy connections, Deagan manufactured instruments in 440Hz and lobbied both in Europe and the US. The American Standards Association officially established 440Hz as standard pitch in 1936.
International Adoption: In May 1939, delegates from France, Germany, Netherlands, Italy, and England met at BBC Broadcasting House in London. They chose 440Hz partly because 439Hz (used by British piano tuners) was a prime number - harder to generate electronically [Wikipedia: A440]. The International Organization for Standardization (ISO) formalized this as ISO 16 in 1955, reaffirmed in 1975 [Gribenski: Tuning the World].
The Controversy: While Joseph Goebbels did attend the 1939 conference representing Germany, the push for 440Hz predated Nazi involvement by decades. French musicians (23,000 polled) preferred 432Hz, but weren't represented at the London conference [Global News]. The standardization was driven more by American manufacturing interests and technical convenience than any conspiracy.
