  <issue>
  multiple definitions of `SoxEffect`.
  `SoxEffect` is defined both in
  
  https://github.com/pytorch/audio/blob/00d38203e401b8d9472a8f8394a10e2c309be02c/torchaudio/torch_sox.h#L50-L54
  
  and
  
  https://github.com/pytorch/audio/blob/00d38203e401b8d9472a8f8394a10e2c309be02c/torchaudio/torch_sox.cpp#L73-L77

  `torch_sox.h` can be included into `torch_sox.cpp` so that `SoxEffect` needs to be defined
  only once in the header.
