In response to a fast recovery scheme for musical note transcription of an acoustic guitar, a high-resolution real-time musical note recognition system is developed. A TMS320C50 Digital Signal Processing (DSP) Starter Kit was used to interface an acoustic guitar to an IBM PC. A Fast Fourier Transform Algorithm is written in DSP assembly language for pattern extraction and an algorithm use for resolving different harmonics generated by a musical chord of the acoustic guitar. It involves the signal processing of the analog signal coming from a electronic pick-up device which would be passed thru the DSP starter kit and a SoundBlaster card. Each musical tone have a corresponding frequency and note to be display on screen.
