eigenTunes vs RetroPlayer

In 2014, a group of science-and-engineering enthusiasts who loved composing founded eigenTunes. The name eigenTunes combines the prefix of the physics term eigenstate with tunes. Eigenstate, also known as a “quantum state,” describes the measurable quantities of any system in the universe. For an object confined in a box, its eigenstates can be visualized as sine wave functions of different frequencies. By merging this concept with the musical staff, we created our logo. What began as a gathering driven purely by passion gradually evolved into a full-time pursuit as our projects multiplied. Yet whether as a hobby group or a full-time team, what we do has never fundamentally changed. We simply aim to express our emotions and feelings through music in the most genuine way possible and share them with the world. That original intention has never changed—and never will. Because our members come from backgrounds in physics, mathematics, and computer science, we have a strong foundation in programming, algorithms, and hardware. Therefore, we not only create our own musical content but also build playback platforms and custom players to achieve the most refined and immersive expression possible.
