A new parallel bat algorithm for musical note recognition

Music is a universal language that does not require an interpreter, where feelings and sensitivities are united, regardless of the different peoples languages, The proposed system consists two main stages: process extracting important properties using linear discrimination analysis (LDA) This step carried out after initial treatment various procedures to remove musical lines, second stage describes recognition bat algorithm, which one metaheuristic algorithms modifying algorithm obtain better discriminating results. was supported by parallel implementation (Developed Bat Algorithm DBA), increased speed significantly. method applied 1250 images notes. implemented MATLAB R2016a, Work done on Windows10 Processor OS (Intel ® Core TM i5-7200U CPU @ 2.50GHZ 2.70GHZ) computer.
