+class PyTorchaudio(PythonPackage):
+    """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 is 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."""
