espnet2.layers.augmentation.equalization_filtering(waveform, sample_rate: int, center_freq: int = 1000, gain: float = 0.0, Q: float = 0.707)

Equalization filter the input signal.

• Parameters:
  • waveform (torch.Tensor) – audio signal (…, time)
  • sample_rate (int) – sampling rate in Hz
  • center_freq (int) – filter’s center frequency
  • gain (float or torch.Tensor) – desired gain at the boost (or attenuation) in dB
  • Q (float or torch.Tensor) – https://en.wikipedia.org/wiki/Q_factor
• Returns: filtered signal (…, time)
• Return type: ret (torch.Tensor)
