| Abstract: | This study introduces advanced improvements to previous methods for automated score recognition and soprano recorder performance, addressing limitations in playback speed, accuracy, and sound quality. The score recognition system now employs an enhanced method for identifying and removing staff lines, which improves the distinction of musical symbols. In addition, a refined approach is used to classify notes by their placement on the staff, supporting accurate pitch assignment and musical sequencing. The playback mechanism has also been upgraded by replacing traditional motor-driven finger actuators with a solenoid-based multi-valve system, which optimizes performance speed and reduces mechanical noise. The recorder's pitch control now incorporates a 9-valve configuration, offering more precise air pressure regulation across an extended range from bass to treble, thereby addressing pitch stability and tonal accuracy issues. Further, automated tuning is achieved through advanced fuzzy control, which significantly enhances tuning speed and fidelity. Experimental results confirm that these refinements enable substantial improvements in tonal precision and overall performance quality for automated soprano recorder systems. |
