      Improve speech enhancement tutorial (#2527) · d6267031
      Zhaoheng Ni authored
      Summary:
      - The "speech + noise" mixture still has a high SNR, which can't show the effectiveness of MVDR beamforming. To make the task more challenging, amplify the noise waveform to reduce the SNR of mixture speech.
      - Show the Si-SNR score of mixture speech when visualizing the mixture spectrogram.
      - FIx the figure in `rtf_power` subsection.
          - The description of enhanced spectrogram by `rtf_power` is wrong. Correct it to `rtf_power`.
      - Print PESQ, STOI, and SDR metric scores.

      Update MVDR beamforming tutorial (#2398) · d01f5891
      Zhaoheng Ni authored
      Summary:
      - Use `download_asset` to download audios.
      - Replace `MVDR` module with new-added `SoudenMVDR` and `RTFMVDR` modules.
      - Benchmark performances of `F.rtf_evd` and `F.rtf_power` for RTF computation.
      - Visualize the spectrograms and masks.
