Dual Bluetooth Audio Switcher — HD Output & Dual-Screen Spectrum

A refined dual-Bluetooth audio switcher built for desktop setups. It connects two Bluetooth sources and switches between them, feeds a high-definition output, and lets you set the output volume digitally — the last value is remembered across power cycles. USB-powered for clean desktop integration, it adds a glowing dual-screen spectrum that reacts to the music, doubling as an ambient visualizer while the switcher does its job. Ideal for upgrading a speaker, amp or display chain without losing flexible input selection.
