description         Data manipulation and transformation for audio \
                    signal processing, powered by PyTorch

long_description    The aim of torchaudio is to apply PyTorch to the \
                    audio domain. By supporting PyTorch, torchaudio \
                    follows the same philosophy of providing strong \
                    GPU acceleration, having a focus on trainable \
                    features through the autograd system, and having \
                    consistent style (tensor names and dimension \
                    names). Therefore, it is primarily a machine \
                    learning library and not a general signal \
                    processing library. The benefits of PyTorch can be \
                    seen in torchaudio through having all the \
                    computations be through PyTorch operations which\
                    makes it easy to use and feel like a natural \
                    extension.
