| 后者的起始频率为前者的中心频率 | The starting frequency of the latter is the center frequency of the former |
| 对此信号分帧、加窗之后，对其进行离散傅里叶变换，即可得到stft矩阵。 | After framing and windowing this signal, a discrete Fourier transform is applied to it to obtain the stft matrix. |
| This matrix represents the signal in the time-frequency domain over short overlapping windows. | 此矩阵在跨越多个短重叠窗口的时频域表示这个信号 |
| 在低频区分布稀疏 | are sparsely distributed in the high frequency region. |
