✧༺ 📜📡 Signals, Frequencies, Perception 🧠༻✧ When two different frequencies are mixed, physics calls it the heterodyne effect — a process that generates new sum and difference frequencies. This principle underlies radio tuning, oscillators, and signal processing. But the passage reveals something subtle and easily misunderstood: 🎧 Heterodyned beat frequencies ✔ Electronically produced ✔ Recordable by devices ✔ Detectable with one ear 🧠 Binaural beats ✖ Not electronically mixed ✖ Not directly
