Unverified实时音频和弦检测的难点在于FFT窗口长度的权衡：窗口越长频率分辨率越高但时间延迟越大，窗口越短则频率分辨率不足以区分相邻音高69% similarVerifiedAudio visualization is typically based on Fast Fourier Transform (FFT) for frequency-domain analysis of audio signals.68% similarUnverifiedAt an 11 kHz sample rate and a 1024-sample frame, one FFT bin is about 11 Hz wide, wider than the spacing between adjacent notes below A3, so it cannot be used for harmonic analysis.67% similarUnverifiedOFDM技术通过循环前缀将多径效应转化为可均衡的频率选择性衰落，使每个子载波成为独立的感知维度65% similarUnverifiedThe Fourier transform in signal processing maps time-domain signals to the complex frequency domain, with the core idea being to decompose a signal into a superposition of complex exponentials e^{iωt} at different frequencies.64% similar
