Detection of polyphonic notes using embedded systems is a field that has not been explored. This article describes a polyphonic tracking embedded system that can detect on real time single and multiple musical notes, as well as their time duration. The solution was designed on an embedded system with a Cortex M-7 core as processor. This was achieved with an algorithm using fast Fourier transform iterating on two buffers in coordination with the direct memory access peripheral. The proposed embedded system was able to detect multiple musical notes on real time. Future works could use the results of this design and export them to a real music editing format.ITESO, A. C.
