A Real-Time Note Transcription Technique Using Static and Dynamic Window Sizes

This paper presents a real-time signal processing technique using a hardware interface based on the microcontroller to process audio music signals to standard MIDI data. A technique for transcribing music signals by extracting note parameters is described. Two different approaches using static and dynamic window sizes to convert the voice samples for real-time processing without complex calculations are proposed. The transcribed data generated shows the feasibility of using microcontrollers for real-time MIDI generation hardware interface.
