      Update forced alignment tutorial (#2544) · c26b38b2
      moto authored 
      Summary:
1. Fix initialization.
Previously, the SOS token score was initialized to 0 across the time axis.
This was biasing the alignment to delay the start.
The proper way to delay the SOS is via blank token.
The new initilization takes the cumulated sum of blank scores.
2. Fill the end of trellis with Inf
Similar to the start, at the end where there remaining time frame is less
than the number of tokens, it is no longer possible to align the text, thus
we fill with Inf for better visualization.
3. Clean up asset management code.

      Enable CTC decoder in Windows (#2587) · 67cb420d
      moto authored 
      Summary:
This commit enables CTC decoder on Windows.

The functionality seems to work fine.
The tests are passing, the decoding tutorial runs fine.

The only difference to the Linux/macOS version is that
loading model in XZ compression format is not supported.

      Replace 'runtime_error' exception with 'TORCH_CHECK' in TorchAudio sox (#2592) · f234e51f
      Javier Cardenete Morales authored 
      Summary:
Pull Request resolved: https://github.com/pytorch/audio/pull/2592

std::runtime_error does not preserve the C++ stack trace, so it is unclear to users what went wrong internally.

PyTorch's TORCH_CHECK macro allows to print C++ stack trace when TORCH_SHOW_CPP_STACKTRACES environment variable is set to 1.

      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.

      Add documents for SourceSeparationBundle (#2559) · 6cee56ab
      Zhaoheng Ni authored 
      Summary:
- Add documentation page for `SourceSeparationBundle` and `CONVTASNET_BASE_LIBRI2MIX`.
- Add citation of Libri2Mix dataset in the bundle documentation.
- url in integration test should use slash instead of `os.path.join` as it will fail on Windows. Change it to f-string.
