espnet2.gan_svs.utils.expand_f0.expand_f0(f0_frame, hop_length, method='interpolation')

Expand f0 to output wave length.

• Parameters:
  • f0_frame (Tensor) – Input tensor (B, 1, frame_len).
  • hop_length (Tensor) – Hop length.
  • method (str) – Method to expand f0. Choose either ‘interpolation’ or ‘repeat’.
• Returns: Output tensor (B, 1, wav_len).
• Return type: Tensor
