Integrated audio analysis system comprising the pickup, amplifier, MCU and LED display in a single compact unit. This selfcontained design streamlines setup and delivers synchronized signal processing and visualization. Realtime spectrum visualization. The system captures music through the pickup, analyzes the spectrum with the MCU, and displays the results on the LED indicator. This provides immediate visual insight into frequency content as you play, aiding tone shaping and troubleshooting. Adjustable pickup sensitivity. The sensitivity control lets you tailor the input level to your instrument and playing style. This helps prevent distortion from loud playing, ensures clear signals from quieter passages, and improves overall measurement accuracy. Key benefits Simplified integration: all essential components are built in, reducing wiring and setup time. Realtime feedback: instant spectrum visualization supports informed tonal adjustments and technique refinement. Flexible operation: adjustable sensitivity accommodates different pickups and playing dynamics, increasing versatility. Practical use scenarios Home practice and tone exploration: plug in, play, and use the LED display to observe how different techniques affect the spectrum in real time. Studio or rehearsal room checks: quickly assess frequency balance during setup or before recording to ensure clean captures. Educational demonstrations: illustrate fundamental concepts of frequency content to students or collaborators using a tangible, visual reference. Performance attributes Function: realtime spectrum analysis with LED display driven by integrated pickup, amplifier and MCU. Compatibility: designed as an integrated unit using its own pickup, amplifier, MCU and LED components. Size: compact allinone module for easy placement and minimal cabling. Material: built as a consolidated hardware unit (no separate components required for operation). Reliability: single, cohesive system designed for stable, repeatable performance during practice, recording, and demonstrations.
