When synthesizing audio from the short-time Fourier transform (STFT) sometimes you have unknown or noisy phase, and there’s an algorithm called Griffey-Lim that’s pretty common for finding the corresponding time-domain signal. 重采样算法用于实现采样率转换的场景，源于硬件和算法两方面的需求，硬件方面主要是codec，存储，计算和传输等限制，在算法层次，云端ASR，AEC，编码解码中都有可能用到采样率转换，除此以外，在非同源时钟多通道场景，如AEC，beamforming也会用到重采样算法。 The Short-time Fourier transform (STFT), is a Fourier-related transform used to determine the sinusoidal frequency and phase content of local sections of a signal as it changes over time. The output of the function is: 1) a matrix with the complex STFT coefficients with time across the columns and frequency across the rows; 2) a frequency vector; The implementation procedure for the STFT in the discrete domain is carried out by extracting time windows of the original non-stationary signal s(t). With DSP System Toolbox you can design and analyze FIR, IIR, multirate, multistage, and adaptive filters. Eng.
