What is window size in audio?
Window size is the amount of time over which a waveform is sampled, known as time record, expressed in samples. For example, a window size of 128 samples at a sample rate of 48 kHz. Equals a time record of 128 samples x 1/48000 seconds = 0,0027 seconds or 2,7 milliseconds.
What is STFT in librosa?
Short-time Fourier transform (STFT). The STFT represents a signal in the time-frequency domain by computing discrete Fourier transforms (DFT) over short overlapping windows. This function returns a complex-valued matrix D such that. np.abs(D[..., f, t]) is the magnitude of frequency bin f at frame t , and. np.
