WebOct 13, 2024 · if win_length is shorter than n_fft, it will be zero padded on both sides to match the value of n_fft.When computing stft, only the samples multiplying the non-zero window values are used. In other words, if your win_length and hop_length keep the same, and n_fft is increased, the frequency axis will have higher resolution (be up-sampled). WebIn your example, if you drop your sampling rate to something like 4096 Hz, then you only need a 4096 point FFT to achieve 1 Hz bins *4096 Hz, then you only need a 4096 point FFT to achieve 1hz bins and can still resolve a 2khz signal. This reduces the FFT bin size, but also reduces the bandwidth of the signal. continental offers
