Dear fellow audiophile,

Eighty-five years ago, in 1939, musicians worldwide were compelled to conform to tuning their instruments around the A note at the 4th octave, equaling the frequency 440 Hz. While there are many theories about why 440 Hz was chosen, I have not found them particularly important, as nearly all music recorded since then has been tuned and performed live at what is commonly known as “concert pitch.”

The field of sound therapy and healing through music and sound (both audible and ultrasonic) has been extensively researched. Many scientists around the world have demonstrated that various sound frequencies provide healing benefits that enhance overall human performance. Some researchers have even discovered that certain frequencies can kill cancer cells, stop viruses from spreading, cure various diseases, and reverse severe clinical conditions.

While curing acute conditions may require complex medical interventions involving highly specialized instruments, I encountered various sources citing that listening to pure tones and music tuned to ‘Solfeggio Frequencies’ or the popular 432 Hz could be highly beneficial for wellness. These benefits include improving sleep, boosting immunity, and reducing stress and anxiety, among others.

From my conversations with doctors and my readings on the root causes of most chronic medical conditions, I have learned that in 99% of cases, the primary causes of diseases or poor health are attributed to increased levels of stress, anxiety, poor sleep, and compromised immune systems.

When COVID-19 was raging around us, forcing the pandemic to be at the forefront of everyone’s minds, I became determined to learn more about these frequencies and find music already tuned to them. I dove deep into the topic, only to discover that very little music had been retuned or produced to align with these frequencies.

The music I did find on platforms like YouTube and Spotify was mostly meditation music, and there was no reliable way to verify that these tracks were indeed tuned to the claimed frequencies. Furthermore, relying on internet services known for censoring content that challenges their agendas did not seem like a sustainable solution. Not to mention, potential communication blackouts could render these web services useless, leaving users without access.

Since I had a personal library of over 1,000 albums—about 100 GB of music (from my DJ days)—I sought a simple, quick way to retune my existing music for daily listening. I found a few complicated, time-consuming methods to manually retune each song, one by one, using tools like Audacity or DAWs like Ableton. However, I quickly realized these solutions weren’t practical. They required creating new versions of each song for each frequency, significantly increasing storage needs and making my music library unmanageable.

If I had gone down that path, my music player would have ended up with ten versions of every song. Without using shuffle, I could potentially hear the same song ten times in a row, each tuned differently—a highly repetitive and frustrating experience.

I continued searching for a solution—a player that could retune my music in real time. Unfortunately, I found only two apps: one that retuned music to 432 Hz and another for 528 Hz. Both were quite buggy.

Still determined, I decided to leverage my knowledge of building startups and launching products to create my own app.

My goal was simple: I wanted an app that would allow me to infuse the music I already listened to with sound healing benefits by enabling real-time retuning into any Solfeggio frequency or 432 Hz, without altering or converting the original file.
