主要用于对语音信号进行阈值消噪处理，包括软硬阈值消噪-audio signal threshold denoising

Based on the spectrum of the vuvuzela sound, this denoising technique simply computes an antenuation map in the time-frequency domain. Then, the audio signal is restored by computing the inverse STFT. See [1] or [2] for more detail about the algorith
