      Make FFmpeg log level configurable (#2439) · 877a88c5
      moto authored 
      Summary:
Undesired logs are one of the loudest UX complains we get.
Yet, loading media files involves uncertainty which is
difficult to debug without debug log.

This commit introduces utility functions to configure logging level
so that we can ask users to enable it when they encounter an issue,
while defaulting to non-verbose option.

      Add assertion checks to multi-channel functions (#2401) · 38e530d7
      Zhaoheng Ni authored 
      Summary:
- The multi-channel functions only support complex-valued tensors for spectrogram and PSD matrices.
- The mask can be real-valued or complex-valued, hence there is no explicit assertion for mask.
- The shape of input Tensors need to be verified before the computation. For example, the shape of PSD matrix must be `(..., freq, channel, channel)`, the shape of the mask must be `(..., freq, time)`, etc.
- The autograd unittest of `apply_beamforming` has wrong dimensions for beamform_weights detected by the assertion check. FIx it in this PR.

      Summary:
The `LibriLightLimited` dataset is created for fine-tuning SSL models, such as Wav2Vec2 and HuBERT. It is a supervised subset of [Libri-Light](https://github.com/facebookresearch/libri-light) dataset. To distinguish the unsupervised subset and the supervised one, it's clearer to put it in a separate dataset class for fine-tuning purpose.
It contains "10 min", "1 hour", "10 hour" splits.

      Add file-like object support to Streaming API (#2400) · a984872d
      moto authored 
      Summary:
This commit adds file-like object support to Streaming API.

## Features
- File-like objects are expected to implement `read(self, n)`.
- Additionally `seek(self, offset, whence)` is used if available.
- Without `seek` method, some formats cannot be decoded properly.
  - To work around this, one can use the existing `decoder` option to tell what decoder it should use.
  - The set of `decoder` and `decoder_option` arguments were added to `add_basic_[audio|video]_stream` method, similar to `add_[audio|video]_stream`.
  - So as to have the arguments common to both audio and video in front of the rest of the arguments, the order of the arguments are changed.
  - Also `dtype` and `format` arguments were changed to make them consistent across audio/video methods.

## Code structure

The approach is very similar to how file-like object is supported in sox-based I/O.
In Streaming API if the input src is string, it is passed to the implementation bound with TorchBind,
if the src has `read` attribute, it is passed to the same implementation bound via PyBind 11.

![Untitled drawing](https://user-images.githubusercontent.com/855818/169098391-6116afee-7b29-460d-b50d-1037bb8a359d.png)

## Refactoring involved
- Extracted to https://github.com/pytorch/audio/issues/2402
  - Some implementation in the original TorchBind surface layer is converted to Wrapper class so that they can be re-used from PyBind11 bindings. The wrapper class serves to simplify the binding.
  - `add_basic_[audio|video]_stream` methods were removed from C++ layer as it was just constructing string and passing it to `add_[audio|video]_stream` method, which is simpler to do in Python.
  - The original core Streamer implementation kept the use of types in `c10` namespace minimum. All the `c10::optional` and `c10::Dict` were converted to the equivalents of `std` at binding layer. But since they work fine with PyBind11, Streamer core methods deal them directly.

## TODO:
- [x] Check if it is possible to stream MP4 (yuv420p) from S3 and directly decode (with/without HW decoding).

      Refactor Streamer implementation (#2402) · eed57534
      moto authored 
      Summary:
* Move the helper wrapping code in TorchBind layer to proper wrapper class for so that it will be re-used in PyBind11.
* Move `add_basic_[audio|video]_stream` methods from C++ to Python, as they are just string manipulation. This will make PyBind11-based binding simpler as it needs not to deal with dtype.
* Move `add_[audio|video]_stream` wrapper signature to Streamer core, so that Streamer directly deals with `c10::optional`.†

† Related to this, there is a slight change in how the empty filter expression is stored. Originally, if an empty filter expression was given to `add_[audio|video]_stream` method, the `StreamReaderOutputStream` was showing it as empty string `""`, even though internally it was using `"anull"` or `"null"`. Now `StreamReaderOutputStream` shows the corresponding filter expression that is actually being used.

      [codemod][usort] apply import merging for fbcode (8 of 11) · d62875cc
      John Reese authored 
      Summary:
Applies new import merging and sorting from µsort v1.0.

When merging imports, µsort will make a best-effort to move associated
comments to match merged elements, but there are known limitations due to
the diynamic nature of Python and developer tooling. These changes should
not produce any dangerous runtime changes, but may require touch-ups to
satisfy linters and other tooling.

Note that µsort uses case-insensitive, lexicographical sorting, which
results in a different ordering compared to isort. This provides a more
consistent sorting order, matching the case-insensitive order used when
sorting import statements by module name, and ensures that "frog", "FROG",
and "Frog" always sort next to each other.

For details on µsort's sorting and merging semantics, see the user guide:
https://usort.readthedocs.io/en/stable/guide.html#sorting

      Move Streamer API out of prototype (#2378) · 72b712a1
      moto authored 
      Summary:
This commit moves the Streaming API out of prototype module.

* The related classes are renamed as following

  - `Streamer` -> `StreamReader`.
  - `SourceStream` -> `StreamReaderSourceStream`
  - `SourceAudioStream` -> `StreamReaderSourceAudioStream`
  - `SourceVideoStream` -> `StreamReaderSourceVideoStream`
  - `OutputStream` -> `StreamReaderOutputStream`

This change is preemptive measurement for the possibility to add
`StreamWriter` API.

* Replace BUILD_FFMPEG build arg with USE_FFMPEG

We are not building FFmpeg, so USE_FFMPEG is more appropriate

After https://github.com/pytorch/audio/issues/2377

Remaining TODOs: (different PRs)
- [ ] Introduce `is_ffmpeg_binding_available` function.
- [ ] Refactor C++ code:
   - Rename `Streamer` to `StreamReader`.
   - Rename `streamer.[h|cpp]` to `stream_reader.[h|cpp]`.
   - Rename `prototype.cpp` to `stream_reader_binding.cpp`.
   - Introduce `stream_reader` directory.

      Use module-level `__getattr__` to implement delayed initialization (#2377) · 9499f642
      moto authored 
      Summary:
This commit updates the lazy module initialization logic for
`torchaudio.prototype.io` and `torchaudio.prototype.ctc_decoder`.

- The modules are importable regarless of optional dependencies.
i.e. `import torchaudio.prototype.io` does not trigger the check for
optional dependencies.

- Optional dependencies are checked when the actual
API is imported for the first time.
i.e. `from torchaudio.prototype.io import Streamer` triggers the check
for optional dependencies.

The downside is that;

- `import torchaudio.prototype.io.Streamer` no longer works.

## Details:

Starting from Python 3.7, modules can bave `__getattr__` function,
which serves as a fallback if the import mechanism cannot find the
attribute.

This can be used to implement lazy import.

```python
def __getattr__(name):
    global pi
    if name == 'pi':
        import math
        pi = math.pi
        return pi
    raise AttributeError(...)
```

Ref: https://twitter.com/raymondh/status/1094686528440168453

The implementation performs lazy import for the APIs that work with
external/optional dependencies. In addition, it also check if the
binding is initialized only once.

## Why is this preferable approach?

Previously, the optional dependencies were checked at the tiem module
is imported;

https://github.com/pytorch/audio/blob/2f4eb4ac2f48a597825d3631a840afd855fe6b39/torchaudio/prototype/io/__init__.py#L1-L5

As long as this module is in `prototype`, which we ask users to import
explictly, users had control whether they want/do not want to install
the optional dependencies.

This approach only works for one optional dependencies per one module.
Say, we add different I/O library as an optional dependency, we need to
put all the APIs in dedicated submodule. This prevents us from having
flat namespace.
i.e. the I/O modules with multiple optional dependencies would look like

```python
# Client code
from torchaudio.io.foo import FooFeature
from torchaudio.io.bar import BarFeature
```

where the new approach would allow

```python
#client code
from torchaudio.io import FooFeature, BarFeature
```

      Fix CollateFn in HuBERT pre-training recipe (#2296) · 09639680
      Zhaoheng Ni authored 
      Summary:
- When cropping the waveform and corresponding label, we use the formula `torch.div(audio_start - kernel_size * sample_rate, stride * sample_rate, rounding_mode="floor")` to align the audio start and label start indices. However, sometimes the value can be negative, which result in an empty label. The training example will hurt the performance after zero-padding (i.e., the labels are all zero for the input waveform).
This PR fixes the bug by checking if `label_start` is negative, and change it to zero if so.
- If `pad` is True, the `length` should be the length of each waveform instead of the max length. Fix it to make the model ignore the padding component in pre-training.

      Move FFmpeg integrity test from conda smoke test to custom smoke test (#2381) · 9877f544
      moto authored 
      Summary:
Conda package build performs simple smoke test, which is different
from smoke_test jobs we define on our CI jobs.

Currently Conda packaging smoke test verifies the imporatability of
`torchaudio.prototype.io`, which requires FFmpeg 4.

1. We list FFmpeg 4 as runtime requirements, but this means that
conda's dependency resolver takes FFmpeg 4 into consideration.
FFmpeg 5 was release this year, and we can expect that user base
will move to FFmpeg gradually. If user environment has some constraint
on FFmpeg, torchaudio will have conflict and it will prevent users
from install torchaudio.

2. In #2377 the way optional dependency is checked/initialized is changed,
so this Conda smoke test will no longer check the integrity with FFmpeg libraries.

To solve the issues above, this commit moves the part that tests integrity with
FFmpeg libraries to the smoke test we define on CircleCI.

Originally, the CI was executing it in the root directory.
This was fine unless the source code is checked out.
When source code is checked out, performing `import torchaudio` in
root directory would import source torchaudio directory, instead of the

This error is difficult to notice, so this commit introduces common script to
