======================================
.. py:class:: mindspore.dataset.audio.HighpassBiquad(sample_rate, cutoff_freq, Q=0.707)
给音频波形上施加双二阶高通滤波器。
接口实现方式类似于 `SoX库 <http://sox.sourceforge.net/sox.html>`_
参数:
- **sample_rate** (int) - 波形的采样频率如44100单位Hz不能为零。
- **cutoff_freq** (float) - 中心频率单位Hz
- **Q** (float, 可选) - `品质因子 <https://zh.wikipedia.org/wiki/%E5%93%81%E8%B3%AA%E5%9B%A0%E5%AD%90>`_ ,取值范围为(0, 1]。默认值0.707。
异常:
- **RuntimeError** - 当输入音频的shape不为(..., time)。
