Realtime spectrum visualization through LED The device picks up audio via the builtin pickup, analyzes its spectrum, and displays the result on the LED indicator in real time. This lets you see frequency content and dynamics as you play, helping you understand and adjust your tone and technique quickly. Adjustable pickup sensitivity The pickup sensitivity can be adjusted to suit different instruments and playing styles. This ensures accurate, stable spectrum visualization across a wide range of input levels and helps prevent signal clipping or weak displays. Integrated allinone design The system combines the pickup, amplifier stage, MCU, and LED components into a compact, selfcontained unit. This simplifies installation, reduces setup time, and provides consistent performance with a straightforward signal path. Key attributes and performance Function: realtime spectrum analysis and LED visualization of the audio signal. Compatibility: designed to operate with standard pickup signals and typical audio chains. Size: compact, integrated module suitable for easy mounting or integration. Performance: realtime processing, adjustable sensitivity, clear LED spectrum display. Use scenarios Practice room analysis: while playing, observe the spectrum to understand tonal balance across frequencies and strings, guiding technique and tone adjustments. Studio or recording: monitor energy distribution across bands during takes to inform equalization and tonal shaping decisions. Educational demonstrations: visualize frequency content for teaching sound spectrum concepts in classrooms or demonstrations.
