An Efficient Real-Time Pitch Correction System via Field-Programmable Gate Array

In this paper, we present an efficient real-time pitch correction system via Field-Programmable Gate Arrays (FPGAs). We first analyze some of the existing methods for both pitch detection and pitch shift. We then propose novel methods, that can run in real-time with fewer hardware resources for both tasks. After examining the experiment results, we integrate both modules and implement the designed system on an FPGA board. Last, we analyze the system's hardware usage and power consumption.
