      Fix for breadcrumbs displaying "Old version (stable)" on Nightly build (#3333) · 3ffd76c8
      Carl Parker authored 
      Summary:
Previously, `breadcrumbs.html` identified a nightly build version by the prefix "Nightly" which would normally be prepended to the version in `conf.py`. However, the version string is coming through without the "Nightly" prefix, so this change causes `breadcrumbs.html` to key on the substring "dev" instead.

The reason we aren't getting "Nightly" is apparently because the environment variable BUILD_VERSION is available, so `conf.py` is using the value of that env var instead of the version string imported from the `torchaudio` module itself, which actually appears to be incorrect; see below.

If I install torchaudio using

    conda install torchaudio -c pytorch-nightly

then `torchaudio.__version__` returns the incorrect version string:

    2.0.0.dev20230309

      Add cuctc decoder (#3096) · 0a1801ed
      Yuekai Zhang authored 
      Summary:
This PR implements a CUDA based ctc prefix beam search decoder.

Attach serveral benchmark results using V100 below:
|decoder type| model |datasets       | decoding time (secs)| beam size | batch size | model unit | subsampling times | vocab size |
|--------------|---------|------|-----------------|------------|-------------|------------|-----------------------|------------|
| cuctc |  conformer nemo    |dev clean        |7.68s | 8           |  32       | bpe         |    4  | 1000|
| cuctc |  conformer nemo   |dev clean  (sort by length)      |1.6s | 8           |  32       | bpe         |    4  | 1000|
| cuctc |  wav2vec2.0 torchaudio |dev clean                                |22s | 10           |  1       | char         |    2  | 29|
| cuctc |   conformer espnet   |aishell1 test                             | 5s | 10           |  24       | char         |    4  | 4233|

Note:
1.  The design is to parallel computation through batch and vocab axis, for loop the frames axis. So it's more friendly with smaller sequence lengths, larger vocab size comparing with CPU implementations.
2. WER is the same as CPU implementations. However, it can't decode with LM now.

      Add AudioEffector (#3163) · a4036248
      moto authored 
      Summary:
This commit adds a new feature AudioEffector, which can be used to
apply various effects and codecs to waveforms in Tensor.

Under the hood it uses StreamWriter and StreamReader to apply
filters and encode/decode.

This is going to replace the deprecated `apply_codec` and
`apply_sox_effect_tensor` functions.

It can also perform online, chunk-by-chunk filtering.

Tutorial to follow.

      Enhance UX on TorchAudio pages to improve awareness of doc versioning (#3167) · 92f2ea89
      Carl Parker authored 
      Summary:
- Boldface the version-selection UX and increase size by three percent.
- Add text to breadcrumbs to indicate version and stability.
- New `breadcrumbs.html` in `_templates` overrides Sphinx version.

I create a new variable in `conf.py`, **version_stable**, which has the version number for the most-recent stable release. I define this variable in the **html_context** dictionary so that it is visible to the templates.

I use this approach because I was not able to find any other way of discerning the current stable release during the build. Note that the `versions.html` file--which identifies the current stable release--appears to be available only in the **gh-pages** branch and so it is not available at build time.

However, this means that someone will need to update `conf.py` whenever the current stable release changes.
