The Music Genre Classification Using DSP is designed to address a practical problem in the Signal Processing & DSP domain using a combination of sensors, processors, and control logic. It captures real-world inputs through Display for waveforms, processes them with Signal acquisition interface, and produces an automated response that improves efficiency, safety, or user convenience. The project follows a modular hardware and firmware architecture so each subsystem can be developed, tested, and integrated independently, making it an ideal capstone for ECE students in Diploma, B.E., or B.Tech programs.
In many existing solutions, monitoring and control tasks rely on manual intervention, which is slow, error-prone, and unable to provide real-time awareness. Manual operation also increases operational cost and the risk of equipment or data loss when conditions change rapidly. Without an automated, sensor-driven approach using ADC-DAC interface, users cannot react to changing conditions quickly enough, and there is no reliable record of historical behavior for analysis or optimization.
This project proposes an automated system built around Display for waveforms and ADC-DAC interface to continuously sense the environment, process the data using Signal acquisition interface, and trigger the appropriate actuator or alert automatically. The design keeps a clean separation between the sensing stage, the processing core, and the output stage, so the same architecture can be extended to other applications with minimal changes. It provides real-time feedback, stores historical data for analysis, and reduces the need for constant manual supervision.

The system is divided into three blocks: the input block gathers raw physical quantities through Display for waveforms and ADC-DAC interface; the processing block, built around Signal acquisition interface, performs signal conditioning, comparison, and control decisions; and the output block drives Microphone / sensor front-end plus display and alert indicators. A regulated power stage supplies clean voltage to all blocks, and the firmware runs a simple state machine so behaviour is predictable and easy to debug. This layered structure keeps the design testable block by block and makes the project easy to present during viva.
