Hilights

TorchAudio v2.1 introduces the new features and backward-incompatible changes;

1. [BETA] A new API to apply filter, effects and codec
   torchaudio.io.AudioEffector can apply filters, effects and encodings to waveforms in online/offline fashion.
   You can use it as a form of augmentation.
   Please refer to https://pytorch.org/audio/2.1/tutorials/effector_tutorial.html for the examples.
2. [BETA] Tools for forced alignment
   New functions and a pre-trained model for forced alignment were added.
   torchaudio.functional.forced_align computes alignment from an emission and torchaudio.pipelines.MMS_FA provides access to the model trained for multilingual forced alignment in MMS: Scaling Speech Technology to 1000+ languages project.
   Please refer to https://pytorch.org/audio/2.1/tutorials/ctc_forced_alignment_api_tutorial.html for the usage of forced_align function, and https://pytorch.org/audio/2.1/tutorials/forced_alignment_for_multilingual_data_tutorial.html for how one can use MMS_FA to align transcript in multiple languages.
3. [BETA] TorchAudio-Squim : Models for reference-free speech assessment
   Model architectures and pre-trained models from the paper TorchAudio-Squim: Reference-less Speech Quality and Intelligibility measures in TorchAudio were added.
   You can use torchaudio.pipelines.SQUIM_SUBJECTIVE and torchaudio.pipelines.SQUIM_OBJECTIVE models to estimate the various speech quality and intelligibility metrics. This is helpful when evaluating the quality of speech generation models, such as TTS.
   Please refer to https://pytorch.org/audio/2.1/tutorials/squim_tutorial.html for the detail.
4. [BETA] CUDA-based CTC decoder
   torchaudio.models.decoder.CUCTCDecoder takes emission stored in CUDA memory and performs CTC beam search on it in CUDA device. The beam search is fast. It eliminates the need to move data from CUDA device to CPU when performing automatic speech recognition. With PyTorch's CUDA support, it is now possible to perform the entire speech recognition pipeline in CUDA.
   Please refer to https://pytorch.org/audio/2.1/tutorials/asr_inference_with_cuda_ctc_decoder_tutorial.html for the detail.
5. [Prototype] Utilities for AI music generation
   We are working to add utilities that are relevant to music AI. Since the last release, the following APIs were added to the prototype.
   Please refer to respective documentation for the usage.
   • torchaudio.prototype.chroma_filterbank
   • torchaudio.prototype.transforms.ChromaScale
   • torchaudio.prototype.transforms.ChromaSpectrogram
   • torchaudio.prototype.pipelines.VGGISH
6. New recipes for training models.
   Recipes for Audio-visual ASR, multi-channel DNN beamforming and TCPGen context-biasing were added.
   Please refer to the recipes
   • https://github.com/pytorch/audio/tree/release/2.1/examples/avsr
   • https://github.com/pytorch/audio/tree/release/2.1/examples/dnn_beamformer
   • https://github.com/pytorch/audio/tree/release/2.1/examples/asr/librispeech_conformer_rnnt_biasing
7. Update to FFmpeg support
   The version of supported FFmpeg libraries was updated.
   TorchAudio v2.1 works with FFmpeg 6, 5 and 4.4. The support for 4.3, 4.2 and 4.1 are dropped.
   Please refer to https://pytorch.org/audio/2.1/installation.html#optional-dependencies for the detail of the new FFmpeg integration mechanism.
8. Update to libsox integration
   TorchAudio now depends on libsox installed separately from torchaudio. Sox I/O backend no longer supports file-like object. (This is supported by FFmpeg backend and soundfile)
   Please refer to https://pytorch.org/audio/2.1/installation.html#optional-dependencies for the detail.

Backward-incompatible changes

Third-party libraries

In this release, the following third party libraries are removed from TorchAudio binary distributions. TorchAudio now search and link these libraries at runtime. Please install them to use the corresponding APIs.

SoX

libsox is used for various audio I/O, filtering operations.

Pre-built binaries are avaialble via package managers, such as conda, apt and brew. Please refer to the respective documetation.

The APIs affected include;

• torchaudio.load ("sox" backend)
• torchaudio.info ("sox" backend)
• torchaudio.save ("sox" backend)
• torchaudio.sox_effects.apply_effects_tensor
• torchaudio.sox_effects.apply_effects_file
• torchaudio.functional.apply_codec (also deprecated, see below)

Changes related to the removal: #​3232, #​3246, #​3497, #​3035

Flashlight Text

flashlight-text is the core of CTC decoder.

Pre-built packages are available on PyPI. Please refer to https://github.com/flashlight/text for the detail.

The APIs affected include;

• torchaudio.models.decoder.CTCDecoder

Changes related to the removal: #​3232, #​3246, #​3236, #​3339

Kaldi

A custom built libkaldi was used to implement torchaudio.functional.compute_kaldi_pitch. This function, along with libkaldi integration, is removed in this release. There is no replcement.

Changes related to the removal: #​3368, #​3403

I/O

• Switch to the backend dispatcher (#​3241)

To make I/O operations more flexible, TorchAudio introduced the backend dispatcher in v2.0, and users could opt-in to use the dispatcher.
In this release, the backend dispatcher becomes the default mechanism for selecting the I/O backend.

You can pass backend argument to torchaudio.info, torchaudio.load and torchaudio.save function to select I/O backend library per-call basis. (If it is omitted, an available backend is automatically selected.)

If you want to use the global backend mechanism, you can set the environment variable, TORCHAUDIO_USE_BACKEND_DISPATCHER=0.
Please note, however, that this the global backend mechanism is deprecated and is going to be removed in the next release.

Please see #​2950 for the detail of migration work.

• Remove Tensor binding from StreamReader (#​3093, #​3272)

torchaudio.io.StreamReader accepted a byte-string wrapped in 1D torch.Tensor object. This is no longer supported.
Please wrap the underlying data with io.BytesIO instead.

• Make I/O optional arguments kw-only (#​3208, #​3227)

The optional arguments of add_[audio|video]_stream methods of torchaudio.io.StreamReader and torchaudio.io.StreamWriter are now keyword-only arguments.

• Drop the support of FFmpeg < 4.1 (#​3561, 3557)

Previously TorchAudio supported FFmpeg 4 (>=4.1, <=4.4). In this release, TorchAudio supports FFmpeg 4, 5 and 6 (>=4.4, <7). With this change, support for FFmpeg 4.1, 4.2 and 4.3 are dropped.

Ops

• Use named file in torchaudio.functional.apply_codec (#​3397)

In previous versions, TorchAudio shipped custom built libsox, so that it can perform in-memory decoding and encoding.
Now, in-memory decoding and encoding are handled by FFmpeg binding, and with the switch to dynamic libsox linking, torchaudio.functional.apply_codec no longer process audio in in-memory fashion. Instead it writes to temporary file.
For in-memory processing, please use torchaudio.io.AudioEffector.

• Switch to lstsq when solving InverseMelScale (#​3280)

Previously, torchaudio.transform.InverseMelScale ran SGD optimizer to find the inverse of mel-scale transform. This approach has number of issues as listed in #​2643.

This release switches to use torch.linalg.lstsq.

Models

• Improve RNN-T streaming decoding (#​3295, #​3379)

The infer method of torchaudio.models.RNNTBeamSearch has been updated to accept series of previous hypotheses.

bundle = torchaudio.pipelines.EMFORMER_RNNT_BASE_LIBRISPEECH
decoder: RNNTBeamSearch = bundle.get_decoder()

hypothesis = None
while streaming:
    ...
    hypo, state = decoder.infer(
        features,
        length,
        beam_width,
        state=state,
        hypothesis=hypothesis,
    )
    ...
    hypothesis = hypo

### Previously this had to be hypothesis = hypo[0]

Deprecations

Ops

• Update and deprecate torchaudio.functional.apply_codec function (#​3386)

Due to the removal of custom libsox binding, torchaudio.functional.apply_codec no longer supports in-memory processing. Please migrate to torchaudio.io.AudioEffector.

Please refer to for the detailed usage of torchaudio.io.AudioEffector.
