espnet2.layers.augmentation.bandwidth_limitation(waveform, sample_rate: int, res_type='random')

Apply the bandwidth limitation distortion to the input signal.

• Parameters:
  • waveform (np.ndarray) – a single speech sample (…, Time)
  • sample_rate (int) – input sampling rate in Hz
  • fs_new (int) – effective sampling rate in Hz
  • res_type (str) – resampling method
• Returns: bandwidth-limited speech sample (…, Time)
• Return type: ret (np.ndarray)
