标题： Real-Time Piano Note Frequency Detection Using FPGA and FFT Core

摘要： 实时频率分析音乐乐器，如钢琴，是电子调音器、音乐可视化和现场声音监测等领域的重要功能。传统方法通常依赖于基于软件的数字信号处理（DSP），这可能会引入延迟并需要大量的计算能力。相比之下，FPGA（现场可编程门阵列）等硬件平台由于其并行处理能力，能够以更高的速度和确定性执行此类分析。该项目的主要目标是使用基于FPGA的实时快速傅里叶变换（FFT）系统分析数字钢琴的模拟音频信号。 显示英文摘要

摘要： Real-time frequency analysis of musical instruments, such as the piano, is an essential feature in areas like electronic tuners, music visualizers, and live sound monitoring. Traditional methods often rely on software-based digital signal processing (DSP), which may introduce latency and require significant computational power. In contrast, hardware platforms such as FPGAs (Field Programmable Gate Arrays) offer the ability to perform such analyses with greater speed and determinism due to their parallel processing capabilities. The primary objective of this project was to analyze analog audio signals from a digital piano using an FPGA-based real-time Fast Fourier Transform (FFT) system.
